[PATCH 0/2] X32 syscall cleanups

Christoph Hellwig uncovered an issue with how we currently handle X32
syscalls. Currently, we can only use COMPAT_SYS_DEFINEx() for X32
specific syscalls. These changes remove that restriction and allow
native syscalls.

Brian Gerst (2):
x86/x32: Use __x64 prefix for X32 compat syscalls
x86/x32: Convert x32_rt_sigreturn to native syscall
