mm, x86: fix native_pud_clear build error
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: 3e761a42e19c ("mm, x86: fix HIGHMEM64 && PARAVIRT build config for native_pud_clear()") Fixes: a00cc7d9dd93 ("mm, x86: add support for PUD-sized transparent hugepages") Link: http://lkml.kernel.org/r/20170314121330.182155-1-arnd@arndb.de Signed-off-by: Arnd Bergmann <arnd@arndb.de> Ackedy-by: Dave Jiang <dave.jiang@intel.com> Cc: Matthew Wilcox <mawilcox@microsoft.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.
