Subject: linux-user: Move get_elf_hwcap to {i386,x86_64}/elfload.c
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=39476538942f0ae1eff5e03f08399ef1eeca0cc0;p=thirdparty%2Fqemu.git

linux-user: Move get_elf_hwcap to {i386,x86_64}/elfload.c

Change the return type to abi_ulong, and pass in the cpu.
Duplicate the one line function between i386 and x86_64,
as most other additions to elfload.c won't be common.
