https://git.0xinfinity.dev/distro/kernel.git/atom?h=linux-2.6.32.y2009-09-22T14:17:41Zmm: ZERO_PAGE without PTE_SPECIAL2009-09-22T14:17:41ZHugh Dickins2009-09-22T00:03:34Zurn:sha1:62eede62dafb4a6633eae7ffbeb34c60dba5e7b1
Reinstate anonymous use of ZERO_PAGE to all architectures, not just to
those which __HAVE_ARCH_PTE_SPECIAL: as suggested by Nick Piggin.
Contrary to how I'd imagined it, there's nothing ugly about this, just a
zero_pfn test built into one or another block of vm_normal_page().
But the MIPS ZERO_PAGE-of-many-colours case demands is_zero_pfn() and
my_zero_pfn() inlines. Reinstate its mremap move_pte() shuffling of
ZERO_PAGEs we did from 2.6.17 to 2.6.19? Not unless someone shouts for
that: it would have to take vm_flags to weed out some cases.
