after recent commit 5456ffde ("powerpc/spufs: simplify spufs core

Add a Kconfig dependency to prevent this from happening again.

this is dead code. Move it under the #ifdef with the rest of the

Unlike drivers/base/cacheinfo, powerpc cacheinfo code is not exposing
shared_cpu_list under /sys/devices/system/cpu/cpu<n>/cache/index<m>

Add shared_cpu_list to per cpu per index directory to maintain parity
with x86. Some scripts (example: mmtests
https://github.com/gormanm/mmtests) seem to be looking for
shared_cpu_list instead of shared_cpu_map.

Tejun Heo had modified shared_cpu_map_show() to use scnprintf instead
of cpumap_print during support for *pb[l] format. Refer commit
0c118b7b ("powerpc: use %*pb[l] to print bitmaps including
cpumasks and nodemasks").

cpumap_print_to_pagebuf() is a standard function to print cpumap. With
commit 9cf79d11 ("bitmap: remove explicit newline handling using
scnprintf format string"), there is no need to print explicit newline
and trailing null character. cpumap_print_to_pagebuf() internally uses
scnprintf(). Hence replace scnprintf() with cpumap_print_to_pagebuf().

Note: shared_cpu_map_show() in drivers/base/cacheinfo.c already uses
cpumap_print_to_pagebuf().

An extra count on ebb_state.stats.pmc_count[PMC_INDEX(pmc)] is being per-
formed when count_pmc() is used to reset PMCs on a few selftests. This

With CONFIG_OF_ALL_DTBS=y, as set by eg. allmodconfig, we see lots of
warnings about our dts files, such as:

  Warning (pci_bridge): /plb/pciex@d00000000: node name is not "pci"
  or "pcie"

The node name should not particularly matter, it's just a name, and
AFAICS there's no kernel code that cares whether nodes are *named*
"pciex" or "pcie". So shutup these warnings by converting to the name
dtc wants.

As always there's some risk this could break something obscure that
does rely on the name, in which case we can revert.

With hash translation, the hypervisor can hint the LPAR about 16GB contiguous range
via ibm,expected#pages. The kernel marks the range specified in the device tree
as reserved. Avoid doing this when using radix translation. Radix translation
only supports 1G gigantic hugepage and kernel can do the 1G gigantic hugepage
allocation via early memblock reservation. This can be done because with radix
translation pages are not required to be contiguous on the host.

The iommu_table_ops::xchg_no_kill() callback updates TCE. It is quite
possible that not entire table is allocated if it is huge and multilevel
so xchg may also allocate subtables. If failed, it returns H_HARDWARE
for failed allocation and H_TOO_HARD if it needs it but cannot do because
the alloc parameter is "false" (set when called with MMU=off to force
retry with MMU=on).

The problem is that having separate errors only matters in real mode
(MMU=off) but the only caller with alloc="false" does not check the exact
error code and simply returns H_TOO_HARD; and for every other mode
alloc is "true". Also, the function is also called from the ioctl()
handler of the VFIO SPAPR TCE IOMMU subdriver which does not expect
hypervisor error codes (H_xxx) and will expose them to the userspace.

This converts wrong error codes to -ENOMEM.

blrl is not recommended to use as an indirect function call, as it may
corrupt the link stack predictor.

This is not a performance critical path but this should be fixed for
consistency.

Pull pin control fixes from Linus Walleij:
 "Some early fixes collected during the first week after the merge
  window, all pretty self-evident, with the details below. The revert is
  the crucial thing.

   - Fix a warning on the Qualcomm SPMI GPIO chip being instatiated
     twice without a unique irqchip struct

   - Use the noirq variants of the suspend and resume callbacks in the
     Tegra driver

   - Clean up the errorpath on the MCP23s08 driver

   - Revert the use of devm_of_iomap() in the Freescale driver as it was
     regressing the platform

   - Add some missing pins in the Qualcomm IPQ6018 driver

   - Fix a simple documentation bug in the pinctrl-single driver"

* tag 'pinctrl-v5.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:

Pull Kbuild fixes from Masahiro Yamada:

 - fix -gz=zlib compiler option test for CONFIG_DEBUG_INFO_COMPRESSED

 - improve cc-option in scripts/Kbuild.include to clean up temp files

 - improve cc-option in scripts/Kconfig.include for more reliable
   compile option test

 - do not copy modules.builtin by 'make install' because it would break
   existing systems

 - use 'userprogs' syntax for watch_queue sample

* tag 'kbuild-fixes-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild:

Pull powerpc fixes from Michael Ellerman:

 - One fix for the interrupt rework we did last release which broke
   KVM-PR

 - Three commits fixing some fallout from the READ_ONCE() changes
   interacting badly with our 8xx 16K pages support, which uses a pte_t
   that is a structure of 4 actual PTEs

 - A cleanup of the 8xx pte_update() to use the newly added pmd_off()

 - A fix for a crash when handling an oops if CONFIG_DEBUG_VIRTUAL is
   enabled

 - A minor fix for the SPU syscall generation

Rapoport, Nicholas Piggin.
