We have the macro _AC() generally available now
so the calculation of PAGE_SIZE can be made
assembler compatible.
Introduce use of _AC() and kill all users of
ASM_PAGE_SIZE.

The bug was that we were comparing __NR_syscalls to be greater or equal
to the syscall number stored in %r20. __NR_syscalls is one greater than
the last syscall though, so we're loading one entry beyond the end of the
syscall table, and trying to jump to it.

Fix this by only checking that we're greater, alternatively, we could
have compared to (__NR_Linux_syscalls - 1)

Amazingly, parisc was the only arch effected by this...
Convert register-sized loads/stores to always be 32-bit for these fields.

The LWS debugging code on parisc is wrongly enabled due to a bug in the
use of the preprocessor directives. This debugging code is not thread
safe and causes problems with a recent glibc on SMP kernels.

More work towards supporing multiple page sizes on 64-bit. Convert
some assumptions that 64bit uses 3 level page tables into testing
PT_NLEVELS. Also some BUG() to BUG_ON() conversions and some cleanups
to assembler.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
