      MIPS: Select ARCH_KEEP_MEMBLOCK if DEBUG_KERNEL to enable sysfs memblock debug · a8c0f1c6
      Tiezhu Yang 提交于
      In the current code, CONFIG_ARCH_KEEP_MEMBLOCK is not set for MIPS arch,
      memblock_discard() will discard memory and reserved arrays if they were
      allocated, select ARCH_KEEP_MEMBLOCK if DEBUG_KERNEL to give a chance to
      track "memory" and "reserved" memblocks after early boot, with this patch,
      we can see the following two sysfs interfaces under DEBUG_FS.

      mips: lib: uncached: fix non-standard usage of variable 'sp' · 5b058973
      Anders Roxell 提交于
      When building mips tinyconfig with clang the following warning show up:
      
      arch/mips/lib/uncached.c:45:6: warning: variable 'sp' is uninitialized when used here [-Wuninitialized]
              if (sp >= (long)CKSEG0 && sp < (long)CKSEG2)
                  ^~
      arch/mips/lib/uncached.c:40:18: note: initialize the variable 'sp' to silence this warning
              register long sp __asm__("$sp");

                               = 0
      1 warning generated.
      
      Rework to make an explicit inline move, instead of the non-standard use
      of specifying registers for local variables. This is what's written
      from the gcc-10 manual [1] about specifying registers for local
      variables:
      
      "6.47.5.2 Specifying Registers for Local Variables
      .................................................
      [...]
      
      "The only supported use for this feature is to specify registers for
      input and output operands when calling Extended 'asm' (*note Extended
      Asm::).  [...]".
