[Linux-ia64] kernel update (relative to 2.4.0-test10)

From: David Mosberger <davidm_at_hpl.hp.com>
Date: 2000-11-16 18:59:26
Here is the latest IA-64 kernel update.  It's still relative to
test10.  This patch is rather big as it contains the first batch of
code required for the SGI SN1 machine.  Other than that, the following
changes were made:

 - Asit: added workaround for dbr[] access errata
 - Jonathan Nicklin, Patrick O'Rourke: changed locore code to execute
   in virtual mode; with this change, only the (rare) page table accesses are
   now done in physical mode
 - Stephane: cleanup of sal.h; fix unaligned handler to always send SIGBUS
   (not SIGSEGV)
 - Kanoj: fix for ia64_pall_call_static
 - added send_ipi/inX/outX machvec entries; note: both IPI and inX/outX
   are architected in IA-64 and there shouldn't be any need for these
   machvecs; however, there are unfortunately some machines that don't
   follow the architecture and that's why we had to add them; if you're
   a system designer, please follow the IA-64 architecture and do not
   use these machvec entries
 - DCR is now initialized such that all faults are deferred (as requested
   by Intel)
 - cleaned up PCI code and pgtable.h a bit
 - ptce loop info is now maintained per CPU (mostly for cleanliness)
 - width of region id registers is now determined at boot time via
   a call to PAL
 - fix unwind code so it doesn't hang when removing a kernel module

As usual, the full patch can be found at:

 ftp://ftp.kernel.org/pub/linux/kernel/ports/ia64

The file name is linux-2.4.0-test10-ia64-001115.diff*

Enjoy,

	--david
