Cache related issues with DMA rings and performance issues related to
caching are being caused by not properly setting the "dma-coherent" flag
in the device tree entries. Adding it here to correct the issue.

If kernel image extends across alignment boundary, existing
code increases the KASLR offset by size of kernel image. The
offset is masked after resizing. There are cases, where after
masking, we may still have kernel image extending across
boundary. This eventually results in only 2MB block getting
mapped while creating the page tables. This results in data aborts
while accessing unmapped regions during second relocation (with
kaslr offset) in __primary_switch. To fix this problem, round up the
kernel image size, by swapper block size, before adding it for
correction.
For example consider below case, where kernel image still crosses
1GB alignment boundary, after masking the offset, which is fixed
by rounding up kernel image size.
SWAPPER_TABLE_SHIFT = 30
Swapper using section maps with section size 2MB.
CONFIG_PGTABLE_LEVELS = 3
VA_BITS = 39
_text : 0xffffff8008080000
_end : 0xffffff800aa1b000
offset : 0x1f35600000
mask = ((1UL << (VA_BITS - 2)) - 1) & ~(SZ_2M - 1)
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7c
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
offset after existing correction (before mask) = 0x1f37f9b000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
offset (after mask) = 0x1f37e00000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7c
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
new offset w/ rounding up = 0x1f38000000
(_text + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d
(_end + offset) >> SWAPPER_TABLE_SHIFT = 0x3fffffe7d

If one thread mmaps a perf event while another thread in the same mm
is in some context where active_mm != mm (which can happen in the
scheduler, for example), refresh_pce() would write the wrong value
to CR4.PCE. This broke some PAPI tests.

As of commit 438cc81a41e8 ("powerpc/pseries: Automatically resize HPT
for memory hot add/remove"), when running on the pseries platform, we
always attempt to use the PAPR extension to resize the hashed page
table (HPT) when we add or remove memory.
This is fine, but when the extension is not available we'll give a
harmless, but scary warning. Instead check if the firmware supports HPT
resizing before populating the mmu_hash_ops.resize_hpt pointer.

The previously submitted patch did not resolve the random segmentation
faults observed on the phantom buildd system. There are still
unresolved problems with the Debian 4.8 and 4.9 kernels on C8000.
The attached patch removes the flush of the offset map pages and does a
whole data cache flush for large ranges. No other arch flushes the
offset map in these routines as far as I can tell.
I have not observed any random segmentation faults on rp3440 in two

The rdtgroup_kn_unlock waits for the last user to release and put its
node. But it's calling kernfs_put on the node which calls the
rdtgroup_kn_unlock, which might not be the group's directory node, but
another group's file node.
This race could be easily reproduced by running 2 instances
of following script:
mount -t resctrl resctrl /sys/fs/resctrl/
pushd /sys/fs/resctrl/
mkdir krava
echo "krava" > krava/schemata
rmdir krava
popd
umount /sys/fs/resctrl
It triggers the slub debug error message with following command
line config: slub_debug=,kernfs_node_cache.
Call kernfs_put on the group's node to fix it.

Pavel Machek reported the following warning on x86-32:
WARNING: kernel stack frame pointer at f50cdf98 in swapper/2:0 has bad value (null)
The warning is caused by the unwinder not realizing that it reached the
end of the stack, due to an unusual prologue which gcc sometimes
generates for aligned stacks. The prologue is based on a gcc feature
called the Dynamic Realign Argument Pointer (DRAP). It's almost always
enabled for aligned stacks when -maccumulate-outgoing-args isn't set.
This issue is similar to the one fixed by the following commit:
8023e0e2a48d ("x86/unwind: Adjust last frame check for aligned function stacks")
... but that fix was specific to x86-64.
Make the fix more generic to cover x86-32 as well, and also ensure that
the return address referred to by the frame pointer is a copy of the
original return address.

We still get a build error in random configurations, after this has been
modified a few times:
In file included from include/linux/mm.h:68:0,
from include/linux/suspend.h:8,
from arch/x86/kernel/asm-offsets.c:12:
arch/x86/include/asm/pgtable.h:66:26: error: redefinition of 'native_pud_clear'
#define pud_clear(pud) native_pud_clear(pud)
My interpretation is that the build error comes from a typo in __PAGETABLE_PUD_FOLDED,
so fix that typo now, and remove the incorrect #ifdef around the native_pud_clear
definition.

On some DDR controllers, compatible with the sama5d3 one,
the sequence to enter/exit/re-enter the self-refresh mode adds
more constrains than what is currently written in the at91_idle
driver. An actual access to the DDR chip is needed between exit
and re-enter of this mode which is somehow difficult to implement.
This sequence can completely hang the SoC. It is particularly
experienced on parts which embed a L2 cache if the code run
between IDLE calls fits in it...
Moreover, as the intention is to enter and exit pretty rapidly
from IDLE, the power-down mode is a good candidate.
So now we use power-down instead of self-refresh. As we can
simplify the code for sama5d3 compatible DDR controllers,
we instantiate a new sama5d3_ddr_standby() function.

The kernel doesn't boot with both PROFILE_ANNOTATED_BRANCHES=y and KASAN=y
options selected. With branch profiling enabled we end up calling
ftrace_likely_update() before kasan_early_init(). ftrace_likely_update() is
built with KASAN instrumentation, so calling it before kasan has been
initialized leads to crash.
Use DISABLE_BRANCH_PROFILING define to make sure that we don't call
ftrace_likely_update() from early code before kasan_early_init().

Remove the WARNING message associated with multiple NMI handlers as
there are at least two that are legitimate. These are the KGDB and the
UV handlers and both want to be called if the NMI has not been claimed
by any other NMI handler.
Use of the UNKNOWN NMI call chain dramatically lowers the NMI call rate
when high frequency NMI tools are in use, notably the perf tools. It is
required on systems that cannot sustain a high NMI call rate without
adversely affecting the system operation.

Subhransu reported that convert_art_to_tsc() isn't working for him.
The ART to TSC relation is only set up for systems which use the refined
TSC calibration. Systems with known TSC frequency (available via CPUID 15)
are not using the refined calibration and therefor the ART to TSC relation
is never established.
Add the setup to the known frequency init path which skips ART
calibration. The init code needs to be duplicated as for systems which use
refined calibration the ART setup must be delayed until calibration has
been done.
The problem has been there since the ART support was introdduced, but only
detected now because Subhransu tested the first time on hardware which has
TSC frequency enumerated via CPUID 15.
Note for stable: The conditional has changed from TSC_RELIABLE to
TSC_KNOWN_FREQUENCY.
