linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT
Now that we have a new SYSCALL_ALIGN_64BIT define for tracking the 64bit register shift behavior, use it. This allows us to delete duplicated arm/xtensa files, as well as drop a few arch ifdefs from common code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
