Subject: [PARISC] Delete arch/parisc/mm/kmap.c again

I deleted this file from 2.4 5 years ago.  Unfortunately, that change
never got merged to Linus and so when we switched to 2.5 it came back
and nobody noticed.  It's never been built in 2.5/2.6 as it was never
in the Makefile.

Subject: [PARISC] Unbreak discontigmem mem_init()

The `simple' way of walking and checking PageReserved is broken on
discontigmem, instead we need to check each range explicitly.

(Also rename a few things so they make more sense.)

Subject: [PARISC] Remove sched.h from uaccess.h on parisc

Al Viro did this for x86-64 and reduced the number of dependencies on
sched.h significantly.  We had a couple of files which were relying on
uaccess.h pulling in sched.h, so they need explicit dependencies added.

Subject: [PARISC] Fix show_stack() when we can't kmalloc

show_stack() was calling kzalloc() to allocate a struct pt_regs.
This meant that *really* early stack dumps would cause a null pointer
dereference.  x86_64 allocates its pt_regs on the stack, so do the same.

Kyle actually committed this exact patch to CVS on
Wed Jul 26 14:32:39 2006 UTC, and never moved it across to git.
Bad Kyle.

Subject: [PARISC] Compat signal fixes for 64-bit parisc

In copy_siginfo_from_user32:
Use compat_uptr_t. Use compat_ptr().

In copy_siginfo_to_user32:
Use compat_int_t. Use ptr_to_compat().

The sigevent_t structure has a 64-bit si_ptr field
that when copied to a 32-bit si_ptr will copy the wrong
word. For the compat copy use the si_int field instead.
