[Qemu-devel] [PATCH] linux-user: Add TARGET_MAP_STACK and TARGET_MAP_HUGETLB for all remaining architectures

[Helge Deller <deller@gmx.de>]

Add the missing defines and for TARGET_MAP_STACK and TARGET_MAP_HUGETLB
for alpha, mips, ppc and x86, and fix the mmap_flags translation table
to translate those flags between host and target architecture.
