x86/entry: Remove do_notify_resume(), syscall_trace_leave(), and their TIF masks
...
They are no longer used. Good riddance!
Deleting the TIF_ macros is really nice. It was never clear why
there were so many variants.

x86/entry: Move C entry and exit code to arch/x86/entry/common.c
...
The entry and exit C helpers were confusingly scattered between
ptrace.c and signal.c, even though they aren't specific to
ptrace or signal handling. Move them together in a new file.
This change just moves code around. It doesn't change anything.

It has no users and it doesn't look useful. I do not know why/when it was
introduced, I can't even find any user in the git history.

Only alpha and sparc are unusual - they have ka_restorer in it.
And nobody needs that exposed to userland.

asm-generic: rename termios.h, signal.h and mman.h

The existing asm-generic versions are incomplete and included
by some architectures. New architectures should be able
to use a generic version, so rename the existing files and
change all users, which lets us add the new files.

x86: Fix ASM_X86__ header guards
...
Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
