This patch makes arch-independent testcases for RODATA. Both x86 and
x86_64 already have testcases for RODATA, But they are arch-specific
because using inline assembly directly.
And cacheflush.h is not a suitable location for rodata-test related
things. Since they were in cacheflush.h, If someone change the state of
CONFIG_DEBUG_RODATA_TEST, It cause overhead of kernel build.
To solve the above issues, write arch-independent testcases and move it
to shared location.

Apart from adding the helper function itself, the rest of the kernel is
converted mechanically using:
git grep -l 'atomic_inc.*mm_users' | xargs sed -i 's/atomic_inc(&\(.*\)->mm_users);/mmget\(\1\);/'
git grep -l 'atomic_inc.*mm_users' | xargs sed -i 's/atomic_inc(&\(.*\)\.mm_users);/mmget\(\&\1\);/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

Fix typos and add the following to the scripts/spelling.txt:
aligment||alignment
I did not touch the "N_BYTE_ALIGMENT" macro in
drivers/net/wireless/realtek/rtlwifi/wifi.h to avoid unpredictable
impact.
I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because
it is surrounded by #if 0 ... #endif. It is surely safe and I
confirmed "_alignment_handler" is correct.
I also fixed the "controler" I found in the same hunk in
arch/openrisc/kernel/head.S.

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the

"userland" etc., so must draw a line somewhere.

Often all is needed is these small helpers, instead of compiler.h or a
full kprobes.h. This is important for asm helpers, in fact even some
asm/kprobes.h make use of these helpers... instead just keep a generic
asm file with helpers useful for asm code with the least amount of
clutter as possible.
Likewise we need now to also address what to do about this file for both
when architectures have CONFIG_HAVE_KPROBES, and when they do not. Then
for when architectures have CONFIG_HAVE_KPROBES but have disabled
CONFIG_KPROBES.
Right now most asm/kprobes.h do not have guards against CONFIG_KPROBES,
this means most architecture code cannot include asm/kprobes.h safely.
Correct this and add guards for architectures missing them.
Additionally provide architectures that not have kprobes support with
the default asm-generic solution. This lets us force asm/kprobes.h on
the header include/linux/kprobes.h always, but most importantly we can
now safely include just asm/kprobes.h on architecture code without
bringing the full kitchen sink of header files.
Two architectures already provided a guard against CONFIG_KPROBES on its
kprobes.h: sh, arch. The rest of the architectures needed gaurds added.
We avoid including any not-needed headers on asm/kprobes.h unless
kprobes have been enabled.
In a subsequent atomic change we can try now to remove compiler.h from
include/linux/kprobes.h.
During this sweep I've also identified a few architectures defining a
common macro needed for both kprobes and ftrace, that of the definition
of the breakput instruction up. Some refer to this as
BREAKPOINT_INSTRUCTION. This must be kept outside of the #ifdef
CONFIG_KPROBES guard.

Pull rdma DMA mapping updates from Doug Ledford:
"Drop IB DMA mapping code and use core DMA code instead.
Bart Van Assche noted that the ib DMA mapping code was significantly
similar enough to the core DMA mapping code that with a few changes it
was possible to remove the IB DMA mapping code entirely and switch the
RDMA stack to use the core DMA mapping code.
This resulted in a nice set of cleanups, but touched the entire tree
and has been kept separate for that reason."

This patch adds a new API to indicate S0ix residency in usec. It utilizes
the PMC Global Control Registers (GCR) to read deep and shallow
S0ix residency.
PMC MMIO resources:
o Lower 4kB: IPC1 (PMC inter-processor communication) interface
o Upper 4kB: GCR (Global Control Registers)
This enables the power management framework to take corrective actions when
the platform fails to enter S0ix after kernel freeze as part of the suspend
to idle flow. (echo freeze > /sys/power/state).
This is expected to be used with a S0ix failsafe framework such as:

shmem_fs.h must then provide the inline stub for shmem_mapping() when
CONFIG_SHMEM is not set, and a few more cfiles now need to #include it.

With this our protnone becomes a present pte with READ/WRITE/EXEC bit

now used to help us identify a protnone pte that as saved write bit.
For such pte, we will clear the _PAGE_PRIVILEGED bit. The pte still
remain non-accessible from both user and kernel.

Most users of this interface just want to use it with the default

called from a different context.
No functional change yet, just passing through the flag to the
underlying alloc_contig_range function.

When a non-cooperative userfaultfd monitor copies pages in the
background, it may encounter regions that were already unmapped.
Addition of UFFD_EVENT_UNMAP allows the uffd monitor to track precisely
changes in the virtual memory layout.
Since there might be different uffd contexts for the affected VMAs, we
first should create a temporary representation for the unmap event for
each uffd context and then notify them one by one to the appropriate
userfault file descriptors.
The event notification occurs after the mmap_sem has been released.

The current transparent hugepage code only supports PMDs. This patch
adds support for transparent use of PUDs with DAX. It does not include
support for anonymous pages. x86 support code also added.
Most of this patch simply parallels the work that was done for huge
PMDs. The only major difference is how the new ->pud_entry method in
mm_walk works. The ->pmd_entry method replaces the ->pte_entry method,
whereas the ->pud_entry method works along with either ->pmd_entry or
->pte_entry. The pagewalk code takes care of locking the PUD before
calling ->pud_walk, so handlers do not need to worry whether the PUD is
stable.

Originally openrisc spec 0 specified that r0 would be wired to ground.
This is no longer the case. r0 is not guaranteed to be 0 at init, so we
need to initialize it to 0 before using it.
Also, if we are clearing r0 we cant use r0 to clear itself. Change the
the CLEAR_GPR macro to use movhi for clearing.

Use execption SR stored in pt_regs for detection, the current SR is not
correct as the handler is running after return from exception.
Also, The code that checks for a delay slot uses a flag bitmask and then
wants to check if the result is not zero. The test it implemented was
wrong.
Correct it by changing the test to check result against non zero.
