[IA64] Tighten up unw_unwind_to_user check
Detect user space by the unwind frame with predicate PRED_USER_STACK
set, instead of a user space IP. Tighten up the last ditch check for
running off the top of the kernel stack.
Based on a suggestion by David Mosberger, reworked to fit the current
tree. This survives my stress test which used to break 2.6.9 kernels.
Unlike 2.6.11, the stress test now unwinds to the correct point, so
gdb can get the user space registers.

[PATCH] ia64: force all kernel sections into one and the same segment
Older versions of the linker do not handle cross-segment segment-relative
relocations properly. This becomes a real problem when the linker decides
to put .text and .text.init into different segments (for whatever reasons)
because in that case, broken linkers will produce a broken unwind section,
which can cause nasty Heisenbugs, where, for example, unwinding may or may
not work depending on the exact value of the IP in a function.
[Backport of Keith Owens' 2.6 change]
Thanks!

ia64: fix HUGETLB null pointer dereference
If the mmap fails, do_mmap_pgoff attempts to unmap the vma range it
was mapping. Depending on where it failed during the mmap, some of the
higher level PGD/PMDs may not have been assigned, so referencing them
may cause NULL pointer dereferences.
If you attempt to allocate a LOT more huge pages than are physically
available, the kernel may reference invalid PGDs or PMDs.
Here is the 2.4 backtrace of a failure. If the mmap fails,
do_mmap_pgoff attempts to unmap the vma range it was mapping.
Depending on where it failed during the mmap, some of the higher level
PGD/PMDs may not have been assigned.
The bug (at least in 2.4) exists on all platforms but on our platform
attempts to dereference NULL pointers usually cause MCAs. (If a
platform has zeros in page 0, you may be lucky & the code would appear
to work, but it is still a bug).

<kaos@sgi.com> (04/03/04 1.1318)
ia64: copy SAL records so we don't drop them when events occur fast
Taking a copy of the record ensures that a continuous stream of CPE or
CMC errors will still process some of the records. Using a copy also
saves space. The buffers in mca.c are maximum size and are permanently
allocated. Doing a kmalloc in salinfo_log_wakeup uses smaller records
(actual size rather than maximum) and the records will only exist for
as long as they are required.

ia64: Back-port from libunwind: fix off-by-one error in kernel-unwinder.
There are no known failures due to this bug, but it's clearly a bug and
given the right compiler, it could trigger and lead to bad stack traces etc.
<kaos@sgi.com> (04/03/03 1.1315)
ia64: add OEM data decode for SGI MCA handler
salinfo_decode can call into the kernel to decode oem data, via the
optional and platform specific program called salinfo_decode_oem. SGI
SN platforms decode oemdata by calling from kernel into the prom.

ia64: unwind: Add some UNW_DEBUG stuff and remove KDB bits to follow 2.6.
<kaos@sgi.com> (04/03/03 1.1313)
ia64: update unwind with 2.6 fixes.
The unwind code in 2.4.25 has drifted away from the 2.6.3 version,
including some missing bug fixes. This patch bring 2.4.25 unwind as
close to 2.6.3 as possible. Changes are :-
* Move unw_table_entry from one header to another.
* Add Fenghua Yu's change to pt_regs_off. This is not really in 2.4
yet, even though the comment says it is.
* Comment and white space changes.
* Bug fix to alloc_reg_state().
* Replace struct_offset() with offsetof().
* Export unw_* symbols.
* Avoid deadlock on script->lock.
I am not happy with the kludge that avoids the deadlock on
script->lock, anybody got a better solution? The kludge assumes that
the first field in an ia64 rwsem is a spinlock. I have hit this unwind
deadlock a couple of times during processing of asynchronous MCA
events, so I want it fixed.
After this patch, the main differences between 2.4 and 2.6 are the
handing of the gate page and its DSO data.

ia64: Fix and optimize sys32_rt_sigtimedwait().
Don't pass garbage timespec to sys_rt_sigtimedwait()
when the user supplied NULL, and optimize uinfo slightly.
<kaos@sgi.com> (04/02/18 1.1310)
ia64: Delete redundant ia64_mca_check_errors
salinfo automatically processes all record types on all cpus at boot
time, ia64_mca_check_errors is now redundant. This also removes the
need for a called_from_init flag on ia64_mca_log_sal_error_record.
<kaos@ocs.com.au> (04/02/11 1.1308)
ia64: remove include/asm-ia64/offset.hs in "make mrproper"
Some generated files are not being removed by make clean/mrproper.
include/asm-ia64/offsets.h is built by 'make dep' so must be removed by
'make mrproper', otherwise 'make dep clean' fails.

<bjorn.helgaas@hp.com> (04/02/10 1.1304)
ia64: (desc_abi): Check for Linux ABI # (3) instead of SysV4 ABI # (0).
This and the corresponding change to arch/ia64/kernel/entry.h:
(PT_REGS_SAVES): Add unwabi 3 directive (the official Linux ABI #).
are tied to the pt_regs rearrangement in the "kernel entry exit
optimization" patch from Rohit Seth, Fengua Yu, and Arun Sharma:
The main items covered by this patch are:
1) Support for 16 bytes instructions as per SDM2.1 (CSD/SSD in pt_regs)
2) f10-f11 are added as additional scratch registers for kernel's use.
3) Re-arrange pt_regs to access less cache lines in system call. Reduce
scratch register saving/restoring in system call path.
4) A few instruction reorg in low-level code.
