Add linux/cacheflush.h
Many architectures do not include asm-generic/cacheflush.h, so turn
the includes on their head and add linux/cacheflush.h which includes
asm/cacheflush.h.
Move the flush_dcache_folio() declaration from asm-generic/cacheflush.h
to linux/cacheflush.h and change linux/highmem.h to include
linux/cacheflush.h instead of asm/cacheflush.h so that all necessary
places will see flush_dcache_folio().
More functions should have their default implementations moved in the
future, but those are for follow-on patches. This fixes csky, sparc and
sparc64 which were missed in the commit which added flush_dcache_folio().

Staging driver update for 5.16-rc1
Here is the big set of staging driver updates and cleanups for 5.16-rc1.
Overall we ended up removing a lot of code this time, a bit over 20,000
lines are now gone thanks to a lot of cleanup work by many developers.
Nothing huge in here functionality wise, just loads of cleanups:
- r8188eu driver major cleanups and removal of unused and dead
code
- wlan-ng minor cleanups
- fbtft driver cleanups
- most driver cleanups
- rtl8* drivers cleanups
- rts5208 driver cleanups
- vt6655 driver cleanups
- vc04_services drivers cleanups
- wfx cleanups on the way to almost getting this merged out of
staging (it's close!)
- tiny mips changes needed for the mt7621 drivers, they have
been acked by the respective subsystem maintainers to go
through this tree.
All of these have been in linux-next for a while with no reported
issues.

mips: cm: Convert to bitfield API to fix out-of-bounds access
mips_cm_error_report() extracts the cause and other cause from the error
register using shifts. This works fine for the former, as it is stored
in the top bits, and the shift will thus remove all non-related bits.
However, the latter is stored in the bottom bits, hence thus needs masking
to get rid of non-related bits. Without such masking, using it as an
index into the cm2_causes[] array will lead to an out-of-bounds access,
probably causing a crash.
Fix this by using FIELD_GET() instead. Bite the bullet and convert all
MIPS CM handling to the bitfield API, to improve readability and safety.

Scheduler updates:
- Revert the printk format based wchan() symbol resolution as it can leak
the raw value in case that the symbol is not resolvable.
- Make wchan() more robust and work with all kind of unwinders by
enforcing that the task stays blocked while unwinding is in progress.
- Prevent sched_fork() from accessing an invalid sched_task_group
- Improve asymmetric packing logic
- Extend scheduler statistics to RT and DL scheduling classes and add
statistics for bandwith burst to the SCHED_FAIR class.
- Properly account SCHED_IDLE entities
- Prevent a potential deadlock when initial priority is assigned to a
newly created kthread. A recent change to plug a race between cpuset and
__sched_setscheduler() introduced a new lock dependency which is now
triggered. Break the lock dependency chain by moving the priority
assignment to the thread function.
- Fix the idle time reporting in /proc/uptime for NOHZ enabled systems.
- Improve idle balancing in general and especially for NOHZ enabled
systems.
- Provide proper interfaces for live patching so it does not have to
fiddle with scheduler internals.
- Add cluster aware scheduling support.
- A small set of tweaks for RT (irqwork, wait_task_inactive(), various
scheduler options and delaying mmdrop)
- The usual small tweaks and improvements all over the place

Memory folios

This should be enough infrastructure to support filesystems converting from pages to folios. The point of all this churn is to allow filesystems and the page cache to manage memory in larger chunks than PAGE_SIZE. The original plan was to use compound pages like THP does, but I ran into problems with some functions expecting only a head page while others expect the precise page containing a particular byte. The folio type allows a function to declare that it's expecting only a head page. Almost incidentally, this allows us to remove various calls to VM_BUG_ON(PageTail(page)) and compound_head(). This converts just parts of the core MM and the page cache. For 5.17, we intend to convert various filesystems (XFS and AFS are ready; other filesystems may make it) and also convert more of the MM and page cache to folios. For 5.18, multi-page folios should be ready. The multi-page folios offer some improvement to some workloads. The 80% win is real, but appears to be an artificial benchmark (postgres startup, which isn't a serious workload). Real workloads (eg building the kernel, running postgres in a steady state, etc) seem to benefit between 0-10%. I haven't heard of any performance losses as a result of this series. Nobody has done any serious performance tuning; I imagine that tweaking the readahead algorithm could provide some more interesting wins. There are also other places where we could choose to create large folios and currently do not, such as writes that are larger than PAGE_SIZE.

make[1]: *** [scripts/Makefile.build:277: mm/highmem.o] Error 1
with code produced from `__cmpxchg64' for MIPS64r2 CPU configurations
using CONFIG_32BIT and CONFIG_PHYS_ADDR_T_64BIT.
This is due to MIPS_ISA_ARCH_LEVEL downgrading the assembly architecture
to `r4000' i.e. MIPS III for MIPS64r2 configurations, while there is a
block of code containing a DINS MIPS64r2 instruction conditionalized on
MIPS_ISA_REV >= 2 within the scope of the downgrade.
The assembly architecture override code pattern has been put there for
LL/SC instructions, so that code compiles for configurations that select
a processor to build for that does not support these instructions while
still providing run-time support for processors that do, dynamically
switched by non-constant `cpu_has_llsc'. It went in with linux-mips.org

MIPS: asm: pci: define arch-specific 'pci_remap_iospace()' dependent on 'CONFIG_PCI_DRIVERS_GENERIC'
Some MIPS defconfigs that don't define 'CONFIG_PCI_DRIVERS_GENERIC' but
define 'CONFIG_PCI_DRIVERS_LEGACY' or none of them, can fail when they are
built since definition for 'pci_remap_iospace' is being done in include
file 'arch/mips/include/asm/pci.h' and the specific function implemented
in 'arch/mips/pci/pci-generic.c'. MIPS PCI drivers that don't use generic
PCI core APIs don't really need 'pci_remap_iospace' to be defined at all.
Hence, change definition for 'pci_remap_iospace' to be dependent on the
preprocessor 'CONFIG_PCI_DRIVERS_GENERIC' definition to avoid possible
build problems.

mips, uasm: Add workaround for Loongson-2F nop CPU errata
This patch implements a workaround for the Loongson-2F nop in generated, code, if the existing option CONFIG_CPU_NOP_WORKAROUND is set. Before, the binutils option -mfix-loongson2f-nop was enabled, but no workaround was done when emitting MIPS code. Now, the nop pseudo instruction is emitted as "or ax,ax,zero" instead of the default "sll zero,zero,0". This is consistent with the workaround implemented by binutils.

MIPS: ralink: don't define PC_IOBASE but increase IO_SPACE_LIMIT
Defining PCI_IOBASE results in pci resource handling working but the
addresses generated for IO accesses are wrong since the ioremap in the pci core
function 'pci_parse_request_of_pci_ranges' tries to remap to a fixed virtual
address (PC_IOBASE) which can't work for KSEG1 addresses. To get it working this
way, we would need to put PCI_IOBASE somewhere into KSEG2 which will result in
creating TLB entries for IO addresses, which most of the time isn't needed on
MIPS because of access via KSEG1. So avoid to define PCI_IOBASE and increase
IO_SPACE_LIMIT resource for ralink MIPS platform instead, to get valid IO
addresses for resources from pci core 'pci_address_to_pio' function.

mm: remove flush_kernel_dcache_page
flush_kernel_dcache_page is a rather confusing interface that implements a
subset of flush_dcache_page by not being able to properly handle page
cache mapped pages.
The only callers left are in the exec code as all other previous callers
were incorrect as they could have dealt with page cache pages. Replace
the calls to flush_kernel_dcache_page with calls to flush_dcache_page,
which for all architectures does either exactly the same thing, can
contains one or more of the following:
1) an optimization to defer the cache flush for page cache pages not
mapped into userspace
2) additional flushing for mapped page cache pages if cache aliases
are possible

Pull siginfo si_trapno updates from Eric Biederman: "The full set of si_trapno changes was not appropriate as a fix for the newly added SIGTRAP TRAP_PERF, and so I postponed the rest of the related cleanups. This is the rest of the cleanups for si_trapno that reduces it from being a really weird arch special case that is expect to be always present (but isn't) on the architectures that support it to being yet another field in the _sigfault union of struct siginfo. The changes have been reviewed and marinated in linux-next. With the removal of this awkward special case new code (like SIGTRAP TRAP_PERF) that works across architectures should be easier to write and maintain" * 'siginfo-si_trapno-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signal: Rename SIL_PERF_EVENT SIL_FAULT_PERF_EVENT for consistency signal: Verify the alignment and size of siginfo_t signal: Remove the generic __ARCH_SI_TRAPNO support signal/alpha: si_trapno is only used with SIGFPE and SIGTRAP TRAP_UNK signal/sparc: si_trapno is only used with SIGILL ILL_ILLTRP arm64: Add compile-time asserts for siginfo_t offsets arm: Add compile-time asserts for siginfo_t offsets sparc64: Add compile-time asserts for siginfo_t offsets |

sock: allow reading and changing sk_userlocks with setsockopt
SOCK_SNDBUF_LOCK and SOCK_RCVBUF_LOCK flags disable automatic socket
buffers adjustment done by kernel (see tcp_fixup_rcvbuf() and
tcp_sndbuf_expand()). If we've just created a new socket this adjustment
is enabled on it, but if one changes the socket buffer size by
setsockopt(SO_{SND,RCV}BUF*) it becomes disabled.
CRIU needs to call setsockopt(SO_{SND,RCV}BUF*) on each socket on
restore as it first needs to increase buffer sizes for packet queues
restore and second it needs to restore back original buffer sizes. So
after CRIU restore all sockets become non-auto-adjustable, which can
decrease network performance of restored applications significantly.
CRIU need to be able to restore sockets with enabled/disabled adjustment
to the same state it was before dump, so let's add special setsockopt
for it.
Let's also export SOCK_SNDBUF_LOCK and SOCK_RCVBUF_LOCK flags to uAPI so
that using these interface one can reenable automatic socket buffer
adjustment on their sockets.

MIPS: don't include <linux/genhd.h> in <asm/mach-rc32434/rb.h>
There is no need to include genhd.h from a random arch header, and not doing so prevents the possibility for nasty include loops.

signal: Remove the generic __ARCH_SI_TRAPNO support
Now that __ARCH_SI_TRAPNO is no longer set by any architecture remove all of the code it enabled from the kernel. On alpha and sparc a more explict approach of using send_sig_fault_trapno or force_sig_fault_trapno in the very limited circumstances where si_trapno was set to a non-zero value. The generic support that is being removed always set si_trapno on all fault signals. With only SIGILL ILL_ILLTRAP on sparc and SIGFPE and SIGTRAP TRAP_UNK on alpla providing si_trapno values asking all senders of fault signals to provide an si_trapno value does not make sense. Making si_trapno an ordinary extension of the fault siginfo layout has enabled the architecture generic implementation of SIGTRAP TRAP_PERF, and enables other faulting signals to grow architecture generic senders as well. v1: https://lkml.kernel.org/r/m18s4zs7nu.fsf_-_@fess.ebiederm.org v2: https://lkml.kernel.org/r/20210505141101.11519-8-ebiederm@xmission.com Link: https://lkml.kernel.org/r/87bl73xx6x.fsf_-_@disp2133 Signed-off-by: "Eric W.

compat: make linux/compat.h available everywhere
Parts of linux/compat.h are under an #ifdef, but we end up using more of those over time, moving things around bit by bit. To get it over with once and for all, make all of this file uncondititonal now so it can be accessed everywhere. There are only a few types left that are in asm/compat.h but not yet in the asm-generic version, so add those in the process. This requires providing a few more types in asm-generic/compat.h that were not already there. The only tricky one is compat_sigset_t, which needs a little help on 32-bit architectures and for x86.
