    mm, x86: fix native_pud_clear build error · d0f33ac9
    Arnd Bergmann 提交于
    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.
    
    Fixes: 3e761a42 ("mm, x86: fix HIGHMEM64 && PARAVIRT build config for native_pud_clear()")
    Fixes: a00cc7d9 ("mm, x86: add support for PUD-sized transparent hugepages")
