Re: [PATCH v5 18/32] signal: Consolidate {TS, TLF}_RESTORE_SIGMASK code

In general, there's no need for the "restore sigmask" flag to live in
ti->flags.  alpha, ia64, microblaze, powerpc, sh, sparc (64-bit only),
tile, and x86 use essentially identical alternative implementations,
placing the flag in ti->status.

Replace those optimized implementations with an equally good common
implementation that stores it in a bitfield in struct task_struct
and drop the custom implementations.

Additional architectures can opt in by removing their
TIF_RESTORE_SIGMASK defines.

There is a small typo in the subject, should be "signal: Consolidate
{TS,TIF}_RESTORE_SIGMASK code"
