From: Oleg Nesterov <oleg@xxxxxxxxxx>
commit 66c1b6d74cd7035e85c426f0af4aede19e805c8a upstream.
Move TS_COMPAT back to asm/thread_info.h, close to TS_I386_REGS_POKED.
It was moved to asm/processor.h by b9d989c7218a ("x86/asm: Move the
thread_info::status field to thread_struct"), then later 37a8f7c38339
("x86/asm: Move 'status' from thread_struct to thread_info") moved the
'status' field back but TS_COMPAT was forgotten.
Preparatory patch to fix the COMPAT case for get_nr_restart_syscall()
Fixes: 609c19a385c8 ("x86/ptrace: Stop setting TS_COMPAT in ptrace code")
