[RFC 15/30] x86/entry/64/compat: Set up full pt_regs for all compat syscalls

This is conceptually simpler. More importantly, it eliminates the PTREGSCALL stubs, which were not compatible with the C ABI. This means that C code can call through the compat syscall table. Signed-off-by: Andy Lutomirski --- arch/x86/entry/entry_64_compat.S | 42
