      erofs: avoid refcounting short-lived pages · 1001042e
      Gao Xiang authored
      LZ4 always reuses the decompressed buffer as its LZ77 sliding window
      (dynamic dictionary) for optimal performance.  However, in specific
      cases, the output buffer may not fully contain valid page cache pages,
      resulting in the use of short-lived pages for temporary purposes.
      
      Due to the limited sliding window size, LZ4 shortlived bounce pages can
      also be reused in a sliding manner, so each bounce page can be vmapped
      multiple times in different relative positions by design.  In order to
      avoiding double frees, currently, reuse counts are recorded via page
      refcount, but it will no longer be used as-is in the future world of
      Memdescs.
      
      Just maintain a lookup table to check if a shortlived page is reused.

      Pull clk fixes from Stephen Boyd:
       "A set of clk fixes for the Qualcomm, Mediatek, and Allwinner drivers:
      
         - Fix the Qualcomm Stromer Plus PLL set_rate() clk_op to explicitly
           set the alpha enable bit and not set bits that don't exist
      
         - Mark Qualcomm IPQ9574 crypto clks as voted to avoid stuck clk
           warnings
      
         - Fix the parent of some PLLs on Qualcomm sm6530 so their rate is
           correct
      
         - Fix the min/max rate clamping logic in the Allwinner driver that
           got broken in v6.9
      
         - Limit runtime PM enabling in the Mediatek driver to only
           mt8183-mfgcfg so that system wide resume doesn't break on other
           Mediatek SoCs"

      selftests/powerpc: Fix build with USERCFLAGS set · 8b7f59de
      Michael Ellerman authored
      Currently building the powerpc selftests with USERCFLAGS set to anything
      causes the build to break:
      
        $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
        ...
        gcc -Wno-error    cache_shape.c ...
        cache_shape.c:18:10: fatal error: utils.h: No such file or directory
           18 | #include "utils.h"
              |          ^~~~~~~~~
        compilation terminated.
      
      This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which
      causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at
      all, resulting in none of the usual CFLAGS being passed. That can
      be seen in the output above, the only flag passed to the compiler is
      -Wno-error.
      
      Fix it by dropping the conditional setting of CFLAGS in flags.mk.
      Instead always set CFLAGS, but also append USERCFLAGS if they are set.
      
      Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
      is included by multiple Makefiles (to support partial builds), causing
      CFLAGS to be appended to multiple times. Additionally that would place
      the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
      couldn't override the standard flags. Being able to override the
      standard flags is desirable, for example for adding -Wno-error.
      
      With the fix in place, the CFLAGS are set correctly, including the
      USERCFLAGS:
      
        $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
        ...
        gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"'
        -I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error
        cache_shape.c ...
      
      Fixes: 5553a793 ("selftests/powerpc: Add flags.mk to support pmu buildable")
