LDO7 regulator beside DSI and HDMI provides power for core blocks in Exynos
5433 SoC. Disabling it causes serious current leak - about 200mA.

This file was only including module.h for exception table related
functions. We've now separated that content out into its own file
"extable.h" so now move over to that and avoid all the extra header
content in module.h that we don't really need to compile this file.

One uses "print_modules" so that prevents us removing module.h in
that case, however.
We also delete a duplicate prototype that doesn't need to exist, as
it duplicates content in extable.h

We start with a delete of a duplicate prototype in asm/exception.h
that no longer needs to exist, as it duplicates content in extable.h
and since that header is so small, there is no point trying to
avoid using it.
Then we make sure anyone using search_exception_tables directly or
via the ia64_done_with_exception macro has included extable.h
In the process, we remove an include of moduleloader.h that was
apparently not really required; it would have been fetching in
module.h and hence the previous location of the exception search
function prototypes, but we need not rely on that anymore.

Move ia64_done_with_exception out of asm/uaccess.h (which is widely
used) and into asm/exception.h (like ARM has) and then ensure the
few callers of it include this new header.
Most of the other C content in asm files is implemented in macro form.
So we do that conversion at the same time as the move.
There are two C exception prototypes that move along with the macro.
One of them will become redundant when we switch over to using the
<linux/extable.h> instead of <linux/module.h> header in a subsequent
commit.
Also relocate a couple of the automated asm --> linux uaccess
conversions to preserve the linux and asm independent grouping, since
we are in the file at that location anyway.

kernelci.org reports tons of build warnings for linux-next:
35 WARNING: "memcpy" [fs/fat/msdos.ko] has no CRC!
35 WARNING: "__copy_user" [fs/fat/fat.ko] has no CRC!
32 WARNING: EXPORT symbol "memset" [vmlinux] version generation failed, symbol will not be versioned.
32 WARNING: EXPORT symbol "copy_page" [vmlinux] version generation failed, symbol will not be versioned.
32 WARNING: EXPORT symbol "clear_page" [vmlinux] version generation failed, symbol will not be versioned.
32 WARNING: EXPORT symbol "__strncpy_from_user_nocheck_asm" [vmlinux] version generation failed, symbol will not be versioned.
The problem here is mainly the missing asm/asm-prototypes.h header file
that is supposed to include the prototypes for each symbol that is exported
from an assembler file.
A second problem is that the asm/uaccess.h header contains some but not
all the necessary declarations for the user access helpers.
Finally, the vdso build is broken once we add asm/asm-prototypes.h, so
we have to fix this at the same time by changing the vdso header. My
approach here is to just not look for exported symbols in the VDSO
assembler files, as the symbols cannot be exported anyway.

The 'mpurate' option, historically used for specifying an initial
MPU rate at boot, no longer has any effect due to the supporting
code being removed as it was 'wrong and dangerous' [1].
This patch removes the remaining dead code associated with the
__setup macros to avoid confusion and reduce bloat.

Commit 7f107887d199 ("ARM: dts: imx: Remove skeleton.dtsi") causes boot
issues when the bootloader does not create a 'chosen' node if such node
is not present in the dtb.
The reason for the boot failure is well explained by Javier Martinez
Canillas: "the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info."
, so pass an empty 'chosen' node to fix the boot problem.
This issue has been seen in the kernelci reports with Barebox as
bootloader.
Also pass the 'memory' node in order to fix boot issues on the SolidRun
iMX6 platforms.

Unfortunately the stack protector support we merged recently only works
on some toolchains. If the toolchain is built without glibc support
everything works fine, but if glibc is built then it leads to a panic

The solution is not rc5 material, so revert the support for now. This

In __eeh_clear_pe_frozen_state(), we should pass the flag's value
instead of its address to eeh_unfreeze_pe(). The isolated flag is
cleared if no error returned from __eeh_clear_pe_frozen_state(). We
never observed the error from the function. So the isolated flag should
have been always cleared, no real issue is caused because of the misused
@flag.
This fixes the code by passing the value of @flag to eeh_unfreeze_pe().

Add the TSC value to the MCE record only when the MCE being logged is
precise, i.e., it is logged as an exception or an MCE-related interrupt.
So it doesn't look particularly easy to do without touching/changing a
bunch of places. That's why I'm trying tricks first.
For example, the mce-apei.c case I'm addressing by setting ->tsc only
for errors of panic severity. The idea there is, that, panic errors will
have raised an #MC and not polled.
And then instead of propagating a flag to mce_setup(), it seems
easier/less code to set ->tsc depending on the call sites, i.e.,
are we polling or are we preparing an MCE record in an exception
handler/thresholding interrupt.

Currently, we append the MCA_IPID[InstanceId] to the bank name to create
the sysfs filename. The InstanceId field uniquely identifies a bank
instance but it doesn't look very nice for most banks.
Replace the InstanceId with a simpler, ascending (0, 1, ..) value.
Only use this in the sysfs name when there is more than 1 instance.
Otherwise, just use the bank's name as the sysfs name.

We log a fake bank 128 MCE to note that we're handling a CPU thermal
event. However, this confuses people into thinking that their hardware
generates MCEs. Hijacking MCA for logging thermal events is a gross
misuse anyway and it shouldn't have been done in the first place. And
besides we have other means for dealing with thermal events which are
much more suitable.
So let's kill the MCE logging part.

The compacted-format XSAVES area is determined at boot time and
never changed after. The field xsave.header.xcomp_bv indicates
which components are in the fixed XSAVES format.
In fpstate_init() we did not set xcomp_bv to reflect the XSAVES
format since at the time there is no valid data.
However, after we do copy_init_fpstate_to_fpregs() in fpu__clear(),
as in commit:
b22cbe404a9c x86/fpu: Fix invalid FPU ptrace state after execve()
and when __fpu_restore_sig() does fpu__restore() for a COMPAT-mode
app, a #GP occurs. This can be easily triggered by doing valgrind on
a COMPAT-mode "Hello World," as reported by Joakim Tjernlund and
others:
https://bugzilla.kernel.org/show_bug.cgi?id=190061
Fix it by setting xcomp_bv correctly.
This patch also moves the xcomp_bv initialization to the proper
place, which was in copyin_to_xsaves() as of:
4c833368f0bf x86/fpu: Set the xcomp_bv when we fake up a XSAVES area
which fixed the bug too, but it's more efficient and cleaner to
initialize things once per boot, not for every signal handling
operation.

Ensure that if userspace supplies insufficient data to
PTRACE_SETREGSET to fill all the registers, the thread's old
registers are preserved.
convert_vx_to_fp() is adapted to handle only a specified number of
registers rather than unconditionally handling all of them: other
callers of this function are adapted appropriately.
Based on an initial patch by Dave Martin.

prom_init.c calls 'instance-to-package' twice, but the return
is not checked during prom_find_boot_cpu(). The result is then
passed to prom_getprop(), which could be PROM_ERROR. Add a return check
to prevent this.
This was found on a pasemi system, where CFE doesn't have a working
'instance-to package' prom call.
Before Commit 5c0484e25ec0 ('powerpc: Endian safe trampoline') the area
around addr 0 was mostly 0's and this doesn't cause a problem. Once the
macro 'FIXUP_ENDIAN' has been added to head_64.S, the low memory area
now has non-zero values, which cause the prom_getprop() call
to hang.
mpe: Also confirmed that under SLOF if 'instance-to-package' did fail
with PROM_ERROR we would crash in SLOF. So the bug is not specific to
CFE, it's just that other open firmwares don't trigger it because they
have a working 'instance-to-package'.
Fixes: 5c0484e25ec0 ("powerpc: Endian safe trampoline")
