most of the functions in there are not used in anything that ends up
including that header...

now we don't mix host and guest signal frame layouts anymore; moreover,
we don't need host's struct sigcontext at all.

For one thing, we always block the same signals (IRQ ones - IO, WINCH, VTALRM),
so there's no need to pass sa_mask elements in arguments. For another, the
flags depend only on whether it's an IRQ signal or not (we add SA_RESTART
for them).

We used to generate those, but we hadn't done that for a long
time. No need to bother blocking them for signal handlers.

only sysdep/sigcontext.h uses it and very few definitions are
actually used. The rest refers to symbols that don't even
exist anymore anyway.

the only users are arch getreg()/putreg() and it's easier to handle
it there instead of playing with macros from hell

Move those to sys-.../asm/checksum.h, kill include/asm/checksum.h

It's a plain include of user_constants.h and all (2) users are
including user_constants.h directly prior to that.

It's not x86, where __get_user() is a single dereference; here it's
a single ptrace(2) call in host, which obviously costs a lot more.
IOW, it's cheaper to do copy_{to,from}_user() once than bother with
fields one by one...
