Subject: mm/pgtable-generic.c: fix CONFIG_SWAP=n build
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f95ba941d1bee594d536cdcbf879a0865381b903;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mm/pgtable-generic.c: fix CONFIG_SWAP=n build

mips (and sparc32):

  In file included from arch/mips/include/asm/tlb.h:21,
                   from mm/pgtable-generic.c:9:
  include/asm-generic/tlb.h: In function `tlb_flush_mmu':
  include/asm-generic/tlb.h:76: error: implicit declaration of function `release_pages'
  include/asm-generic/tlb.h: In function `tlb_remove_page':
  include/asm-generic/tlb.h:105: error: implicit declaration of function `page_cache_release'

free_pages_and_swap_cache() and free_page_and_swap_cache() are macros
which call release_pages() and page_cache_release().  The obvious fix is
to include pagemap.h in swap.h, where those macros are defined.  But that
breaks sparc for weird reasons.

So fix it within mm/pgtable-generic.c instead.
