linux-user: Handle TARGET_MAP_STACK and TARGET_MAP_HUGETLB
Add the missing defines and for TARGET_MAP_STACK and TARGET_MAP_HUGETLB for alpha, mips, ppc, x86, hppa. Fix the mmap_flags translation table to translate MAP_HUGETLB between host and target architecture, and to drop MAP_STACK. Signed-off-by: Helge Deller <deller@gmx.de> Message-Id: <20170311183016.GA20514@ls3530.fritz.box> [rth: Drop MAP_STACK instead of translating it, since it is ignored in the kernel anyway. Fix tabs to spaces.] Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
