Masahiro Yamada 87dfb311b7 treewide: replace #include <asm/sizes.h> with #include <linux/sizes.h>
Since commit dccd2304cc ("ARM: 7430/1: sizes.h: move from asm-generic
to <linux/sizes.h>"), <asm/sizes.h> and <asm-generic/sizes.h> are just
wrappers of <linux/sizes.h>.

This commit replaces all <asm/sizes.h> and <asm-generic/sizes.h> to
prepare for the removal.

Martin Schwidefsky a8874e7e8a mm: make the __PAGETABLE_PxD_FOLDED defines non-empty
Change the currently empty defines for __PAGETABLE_PMD_FOLDED,
__PAGETABLE_PUD_FOLDED and __PAGETABLE_P4D_FOLDED to return 1.
This makes it possible to use __is_defined() to test if the
preprocessor define exists.
