powerpc/vdso: Fix DOTSYM for 32-bit LE VDSO
Skirmisher reported on IRC that the 32-bit LE VDSO was hanging. This
turned out to be due to a branch to self in eg. __kernel_gettimeofday.
Looking at the disassembly with objdump -dR shows why:
00000528 <__kernel_gettimeofday>:
528: f0 ff 21 94 stwu r1,-16(r1)
52c: a6 02 08 7c mflr r0
530: f0 ff 21 94 stwu r1,-16(r1)
534: 14 00 01 90 stw r0,20(r1)
538: 05 00 9f 42 bcl 20,4*cr7+so,53c <__kernel_gettimeofday+0x14>
53c: a6 02 a8 7c mflr r5
540: ff ff a5 3c addis r5,r5,-1
544: c4 fa a5 38 addi r5,r5,-1340
548: f0 00 a5 38 addi r5,r5,240
54c: 01 00 00 48 bl 54c <__kernel_gettimeofday+0x24>
54c: R_PPC_REL24 .__c_kernel_gettimeofday
Because we don't process relocations for the VDSO, this branch remains
a branch from 0x54c to 0x54c.
With the preceding patch to prohibit R_PPC_REL24 relocations, we
instead get a build failure:
0000054c R_PPC_REL24 .__c_kernel_gettimeofday
00000598 R_PPC_REL24 .__c_kernel_clock_gettime
000005e4 R_PPC_REL24 .__c_kernel_clock_gettime64
00000630 R_PPC_REL24 .__c_kernel_clock_getres
0000067c R_PPC_REL24 .__c_kernel_time
arch/powerpc/kernel/vdso32/vdso32.so.dbg: dynamic relocations are not supported
The root cause is that we're branching to `.__c_kernel_gettimeofday`.
But this is 32-bit LE code, which doesn't use function descriptors, so
there are no dot symbols.
The reason we're trying to branch to a dot symbol is because we're
using the DOTSYM macro, but the ifdefs we use to define the DOTSYM
macro do not currently work for 32-bit LE.
So like previous commits we need to differentiate if the current
compilation unit is 64-bit, rather than the kernel as a whole. ie.
switch from CONFIG_PPC64 to __powerpc64__.
With that fixed 32-bit LE code gets the empty version of DOTSYM, which
just resolves to the original symbol name, leading to a direct branch
and no relocations:
000003f8 <__kernel_gettimeofday>:
3f8: f0 ff 21 94 stwu r1,-16(r1)
3fc: a6 02 08 7c mflr r0
400: f0 ff 21 94 stwu r1,-16(r1)

408: 05 00 9f 42 bcl 20,4*cr7+so,40c <__kernel_gettimeofday+0x14>

powerpc/vdso: Don't pass 64-bit ABI cflags to 32-bit VDSO
When building the 32-bit VDSO, we are building 32-bit code as part of
a 64-bit kernel build. That requires us to tweak the cflags to trick
the compiler into building 32-bit code for us. The main way we do that
is by passing -m32, but there are other options that affect code
generation and ABI selection.
In particular when building vgettimeofday.c, we end up passing
-mcall-aixdesc because it's in KBUILD_CFLAGS, which causes the
compiler to generate function descriptors, and dot symbols, eg:
$ nm arch/powerpc/kernel/vdso32/vgettimeofday.o
000005d0 T .__c_kernel_clock_getres
00000024 D __c_kernel_clock_getres
...
We get away with that at the moment because we also use the DOTSYM
macro, and that is also incorrectly prepending a '.' in 32-bit VDSO
code due to a separate bug.
But we shouldn't be generating function descriptors for this file,
there's no 32-bit ABI that includes function descriptors, so the
resulting object file is some frankenstein and it's surprising that it
even links.
So filter out all the ABI-related options we add to CFLAGS for 64-bit
builds, so that they're not used when building 32-bit code. With that
we only see regular text symbols:
$ nm arch/powerpc/kernel/vdso32/vgettimeofday.o michael@alpine1-p1
000005d0 T __c_kernel_clock_getres
00000000 T __c_kernel_clock_gettime
00000200 T __c_kernel_clock_gettime64
00000410 T __c_kernel_gettimeofday
00000650 T __c_kernel_time

powerpc/vdso: Block R_PPC_REL24 relocations
Add R_PPC_REL24 relocations to the list of relocations we do NOT
support in the VDSO.
These are generated in some cases and we do not support relocating
them at runtime, so if they appear then the VDSO will not work at
runtime, therefore it's preferable to break the build if we see them.

powerpc/smp: Add __init to init_big_cores()
It fixes this link warning:
WARNING: modpost: vmlinux.o(.text.unlikely+0x2d98): Section mismatch in reference from the function init_big_cores.isra.0() to the function .init.text:init_thread_group_cache_map()
The function init_big_cores.isra.0() references
the function __init init_thread_group_cache_map().
This is often because init_big_cores.isra.0 lacks a __init
annotation or the annotation of init_thread_group_cache_map is wrong.

mm, kvm: account kvm_vcpu_mmap to kmemcg
A VCPU of a VM can allocate couple of pages which can be mmap'ed by the user space application. At the moment this memory is not charged to the memcg of the VMM. On a large machine running large number of VMs or small number of VMs having large number of VCPUs, this unaccounted memory can be very significant. So, charge this memory to the memcg of the VMM. Please note that lifetime of these allocations corresponds to the lifetime of the VMM.

- Always initialize kernel stack backchain when entering the kernel, so
that unwinding works properly.
- Fix stack unwinder test case to avoid rare interrupt stack corruption.
- Simplify udelay() and just let it busy loop instead of implementing a
complex logic.
- arch_cpu_idle() cleanup.
- Some other minor improvements.

RISC-V Patches for the 5.11 Merge Window, Part 1
We have a handful of new kernel features for 5.11:
* Support for the contiguous memory allocator.
* Support for IRQ Time Accounting
* Support for stack tracing
* Support for strict /dev/mem
* Support for kernel section protection
I'm being a bit conservative on the cutoff for this round due to the
timing, so this is all the new development I'm going to take for this
cycle (even if some of it probably normally would have been OK). There
are, however, some fixes on the list that I will likely be sending along
either later this week or early next week.
There is one issue in here: one of my test configurations
(PREEMPT{,_DEBUG}=y) fails to boot on QEMU 5.0.0 (from April) as of the
.text.init alignment patch. With any luck we'll sort out the issue, but
given how many bugs get fixed all over the place and how unrelated those
features seem my guess is that we're just running into something that's
been lurking for a while and has already been fixed in the newer QEMU
(though I wouldn't be surprised if it's one of these implicit
assumptions we have in the boot flow). If it was hardware I'd be
strongly inclined to look more closely, but given that users can upgrade
their simulators I'm less worried about it.
There are two merge conflicts, both in build files. They're both a bit
clunky: arch/riscv/Kconfig is out of order (I have a script that's
supposed to keep them in order, I'll fix it) and lib/Makefile is out of
order (though GENERIC_LIB here doesn't mean quite what it does above).

Tracing updates for 5.11
The major update to this release is that there's a new arch config option called: CONFIG_HAVE_DYNAMIC_FTRACE_WITH_ARGS. Currently, only x86_64 enables it. All the ftrace callbacks now take a struct ftrace_regs instead of a struct pt_regs. If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer. This way, if a user (like live kernel patching) only cares about the arguments, then it can avoid using the heavier weight "regs" callback, that puts in enough information in the struct ftrace_regs to simulate a breakpoint exception (needed for kprobes). New config option that audits the timestamps of the ftrace ring buffer at most every event recorded. The "check_buffer()" calls will conflict with mainline, because I purposely added the check without including the fix that it caught, which is in mainline. Running a kernel built from the commit of the added check will trigger it. Ftrace recursion protection has been cleaned up to move the protection to the callback itself (this saves on an extra function call for those callbacks). Perf now handles its own RCU protection and does not depend on ftrace to do it for it (saving on that extra function call). New debug option to add "recursed_functions" file to tracefs that lists all the places that triggered the recursion protection of the function tracer.

If the architecture has HAVE_DYNAMIC_FTRACE_WITH_ARGS enabled, then the ftrace_regs will have enough information to read the arguments of the function being traced, as well as access to the stack pointer.

arm64: Work around broken GCC 4.9 handling of "S" constraint
GCC 4.9 seems to have a problem with the "S" asm constraint
when the symbol lives in the same compilation unit, and pretends
the constraint is impossible:
$ cat x.c
void *foo(void)
{
static int x;
int *addr;
asm("adrp %0, %1" : "=r" (addr) : "S" (&x));
return addr;
}
$ ~/Work/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux/bin/aarch64-linux-gnu-gcc -S -x c -O2 x.c
x.c: In function ‘foo’:
x.c:5:2: error: impossible constraint in ‘asm’
asm("adrp %0, %1" : "=r" (addr) : "S" (&x));
^
Boo. Following revisions of the compiler work just fine, though.
We can fallback to the "i" constraint for GCC version prior to 5.0,
which *seems* to do the right thing. Hopefully we will be able to
remove this at some point, but in the meantime this gets us going.

ARM: SoC updates for OMAP GenPD
These are additional updates for the power domain support on OMAP, moving to an implementation based on device tree information instead of SoC specific code. This is the latest step in the ongoing process for moving code out of arch/arm/mach-omap2. I kept this separate from the other driver changes since it touches code in multiple areas. There is one conflict in the dra7.dts file, which adds another node in a different branch. Watch out for adding the trailing '};' both times.

ARM: SoC drivers for v5.11
There are a couple of subsystems maintained by other people that
merge their drivers through the SoC tree, those changes include:
- The SCMI firmware framework gains support for sensor notifications
and for controlling voltage domains.
- A large update for the Tegra memory controller driver, integrating
it better with the interconnect framework
- The memory controller subsystem gains support for Mediatek MT8192
- The reset controller framework gains support for sharing pulsed
resets
For Soc specific drivers in drivers/soc, the main changes are
- The Allwinner/sunxi MBUS gets a rework for the way it handles
dma_map_ops and offsets between physical and dma address spaces.
- An errata fix plus some cleanups for Freescale Layerscape SoCs
- A cleanup for renesas drivers regarding MMIO accesses.
- New SoC specific drivers for Mediatek MT8192 and MT8183 power domains
- New SoC specific drivers for Aspeed AST2600 LPC bus control
and SoC identification.
- Core Power Domain support for Qualcomm MSM8916, MSM8939, SDM660
and SDX55.
- A rework of the TI AM33xx 'genpd' power domain support to use
information from DT instead of platform data
- Support for TI AM64x SoCs
- Allow building some Amlogic drivers as modules instead of built-in
Finally, there are numerous cleanups and smaller bug fixes for
Mediatek, Tegra, Samsung, Qualcomm, TI OMAP, Amlogic, Rockchips,
Renesas, and Xilinx SoCs.
There is a trivial conflict in the cedrus driver, with two branches
adding the same CEDRUS_CAPABILITY_H265_DEC flag, and another trivial
remove/remove conflict in linux/dma-mapping.h.

ARM: device tree updates for 5.11
Across all platforms, there is a continued move towards DT schema for
validating the dts files. As a result there are bug fixes for mistakes
that are found using these schema, in addition to warnings from the
dtc compiler.
As usual, many changes are for adding support for additional on-chip
and on-board components in the machines we already support.
The newly supported SoCs for this release are:
- MStar Infinity2M, a low-end IP camera chip based on a dual-core
Cortex-A7, otherwise similar to the Infinity chip we already support.
This is also known as the SigmaStar SSD202D, and we add support for
the Honestar ssd201htv2 development kit.
- Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller
(BMC), in the same family as the NPCM750. This gets used in the Ampere
Altra based "Fii Kudo" server and the Quanta GSJ, both of which are
added as well.
- Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own
Brahma-B53 CPU. Support is also added for the Asus ROG Rapture
GT-AC5300 high-end WiFi router based on this chip.
- Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores,
meant for faster Chromebooks and tablets. It gets added along with
its reference design.
- Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's
generation, also added along with its reference board. This one is
still based on Cortex-A75/A55.
- Mediatek MT8167 is a version of the already supported MT8516 chip,
both based on Cortex-A35. It gets added along with the "Pumpkin"
single board computer, but is likely to also make its way into low-end
tablets in the future.
For the already supported chips, there are a number of new boards.
Interestingly there are more 32-bit machines added this time than
64-bit. Here is a brief list of the new boards:
- Three new Mikrotik router variants based on Marvell Prestera
98DX3236, a close relative of the more common Armada XP
- A reference board for the Marvell Armada 382
- Three new servers using ASpeed baseboard management controllers,
the actual machines being from Bytedance, Facebook and IBM,
and one machine using the Nuvoton NPCM750 BMC.
- The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412.
- The usual set of 32-bit i.MX industrial/embedded hardware:
* Protonic WD3 (tractor e-cockpit)
* Kamstrup OMNIA Flex Concentrator (smart grid platform)
* Van der Laan LANMCU (food storage)
* Altesco I6P (vehicle inspection stations)
* PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard
- DH electronics STM32MP157C DHCOM, a PicoITX carrier board
for the aleady supported DHCOM module
- Three new Allwinner SoC based single-board computers:
* NanoPi R1 (H3 based)
* FriendlyArm ZeroPi (H3 based)
* Elimo Initium SBC (S3 based)
- Ouya Game Console based on Nvidia Tegra 3
- Version 5 of the already supported Zynq Z-Turn MYIR Board
- LX2162AQDS, a reference platform for NXP Layerscape
LX2162A, which is a repackaged 16-core LX2160A
- A series of Kontron i.MX8M Mini baseboard/SoM versions
- Espressobin Ultra, a new variant of the popular Armada 3700 based board,
- IEI Puzzle-M801, a rackmount network appliance based on
Marvell Armada 8040
- Microsoft Lumia 950 XL, a phone
- HDK855 and HDK865 Hardware development kits for Qualcomm
sm8250 and sm8150, respectively
- Three new board variants of the "Trogdor" Chromebook
(sc7180)
- New board variants of the Renesas based "Kingfisher" and
"HiHope" reference boards
- Kobol Helios64, an open source NAS appliance based on Rockchips
RK3399
- Engicam PX30.Core, a SoM based on Rockchip PX30, along with
a few carrier boards.
There is one conflict in mt6577_auxadc.txt, which got replaced in
another tree and modified here, the modification is already part of
the new file.

ARM: SoC defconfigs for 5.11

"This is the bulk of pin control changes for the v5.11 kernel.
Drivers, drivers and drivers. Not a single core change.
Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot
SoCs.
As part of the modularization attempt, I applied one patch affecting
the firmware subsystem as a functional (not syntactic/semantic)
dependency and then it blew up in our face, so I had to revert it,
bummer. It will come in later, through that subsystem, I guess.

Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL. With that done, we can get rid of JOBCTL_TASK_WORK from task_work and signal.c, and also remove a deadlock work-around in io_uring around knowing that signal based task_work waking is invoked with the sighand wait queue head lock. The motivation for this work is to decouple signal notify based task_work, of which io_uring is a heavy user of, from sighand. The sighand lock becomes a huge contention point, particularly for threaded workloads where it's shared between threads. Even outside of threaded applications it's slower than it needs to be. Roman Gershman <romger@amazon.com> reported that his networked workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all spent hammering on the sighand lock, showing 57% of the CPU time there [1]. There are further cleanups possible on top of this. One example is TIF_PATCH_PENDING, where a patch already exists to use TIF_NOTIFY_SIGNAL instead.

s390/delay: simplify udelay
udelay is implemented by using quite subtle details to make it possible to load an idle psw and waiting for an interrupt even in irq context or when interrupts are disabled. Also handling (or better: no handling) of softirqs is taken into account. All this is done to optimize for something which should in normal circumstances never happen: calling udelay to busy wait. Therefore get rid of the whole complexity and just busy loop like other architectures are doing it also. It could have been possible to use diag 0x44 instead of cpu_relax() in the busy loop, however we have seen too many bad things happen with diag 0x44 that it seems to be better to simply busy loop. Also note that with this new implementation kernel preemption does work when within the udelay loop. This did not work before. To get a feeling what the former code optimizes for: IPL'ing a kernel with 'defconfig' and afterwards compiling a kernel ends with a total of zero udelay calls.
