FILE REMOVED

Merge i386 and amd64 version of db_memrw.c.

Use this opportunity to skip calculating the VA of the page. Let the CPU
deal with the invalidation itself through invlpg + destination address to
avoid converting between canonical/non canonical forms.

Use the current destination address to compute PTE, not the address of
origin.

Harmless, except when db_write_text() passes a page boundary.

From Bug Hunting.

XXX has to be pulled up to -5 and -6.

Use pmap_pte_*bits macros to set/clear bits in a PTE. Remove pmap_pte_flush
calls as these operations are synchronously flushed under Xen; they should
not be cached.

XXX the code can be shared between i386 and amd64, but I will merge
them once I figure out why db_write_text() can cause page faults for
certain CPUs in long mode (code looks correct, but single stepping or
adding debug printf's makes the bug magically disappear... sigh)

Bug reported by David Laight on port-amd64@ when attempting to set
breakpoints through ddb(4).

I am not quite sure that __data_start (set through location counter) is
a char... declare it as int, like amd64.

More i386PAE fixes:
- x86_round_page, x86_trunc_page, x86_btop and x86_ptob macros are used with
  physical addresses; cast to paddr_t instead of u_long. Issue pointed out
  by jym@
- machine_to_phys_mapping[] is a long. This is fine as it holds page
  frame numbers (and this fits in a 32bit int as physical addresses are
  only 36bits), but cast to paddr_t before << PAGE_SHIFT
- xen_start_info.store_mfn is a long; cast it to paddr_t before << PAGE_SHIFT.
  should fix issue pointed out by cegger@

Merge the bouyer-xeni386 branch to head, at tag bouyer-xeni386-merge1 (the
branch is still active and will see i386PAE support developement).
Sumary of changes:
- switch xeni386 to the x86/x86/pmap.c, and the xen/x86/x86_xpmap.c
  pmap bootstrap.
- merge back most of xen/i386/ to i386/i386
- change the build to reduce diffs between i386 and amd64 in file locations
- remove include files that were identical to the i386/amd64 counterparts,
  the build will find them via the xen-ma/machine link.

merge yamt-x86pmap branch.

- reduce differences between amd64 and i386.  notably, share pmap.c
  between them.  it makes several i386 pmap improvements available to
  amd64, including tlb shootdown reduction and bug fixes from Stephan Uphoff.
- implement deferred pmap switching for amd64.
- remove LARGEPAGES option.  always use large pages if available.
  also, make it work on amd64.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

interrupt stuff. This is mostly comprised of changes to the pmap modules to
work on multiprocessor systems without kernel_lock, and changes to speed up
tlb shootdowns.
