This patch removes a ton of pointless big endian defines for some
registers on SN2 and cleans up the #include hierachy making it include
some really big header files only when they are really needed.

This patch changes the kernel such that si_isr gets setup for hardware
breakpoints, single-step, and taken-branch traps.  This is useful, e.g., to
determine what kind of hw breakpoint triggered the signal.

Attached is a small cleanup patch for the sn2 header files which removes
some cases of excessive header file inclusion.

      SBA_PROC_FS off by default (it's too much of a scalability bottleneck).

	the #ifdef __KERNEL__ bracket.  Doing so pollutes the user-
	level namespace.  Bug report & proposed fix by GOTO Masanori.

This patch fixes a typo in pfm_write_pmcs() in the test for the default
value. The code was using the lop index instead of the register
index in the PMC_DFL_VAL() macro. This was causing valid values
for some PMCs to be rejected.

Having this print out for every CPU on a large system was a pain, so
protect the printk with EFI_DEBUG.

This code works pretty well now, so we don't need to dump all this stuff
at boot time (esp. on 128 node systems).

This patch coverts a few spots to use cpumask_t instead of unsigned
long.

If you try to compile 2.6.0-test[45] with spinlock debugging on, then
unwind.c won't compile, because it uses a #define magic that hides
the variable in the spinlock debugging code (also called magic).

MINSIGSTKSZ is defined differently for i386 and ia64. This patch improves
compatibility with apps which use sigaltstack(2) with sizes between
MINSIGSTKSZ_IA32 and MINSIGSTKSZ.

For some reason, we had a structure field called 'current'.  This patch
fixes that.

Fix a couple of sn2 files.

Update the SA11x0 serial driver for the removal of system devices
from the driver model.  The driver becomes a platform device driver.
The driver is now known to the driver model and resource subsytems
as "sa11x0-uart".

	away static variables with no compiler-visible use.

This patch eliminates two unused SN2 header files:
include/asm-ia64/sn/klclock.h and include/asm-ia64/sn/ioc3.h.

Without this, if elv_try_last_merge() returns nonzero, we do not
initialise *req.  That results in a subsequent BUG_ON() in
__make_request() because req is NULL (or is just uninitialised).

Last round of changes broke sdla build if not a module.

drivers whose microcode load ioctl's used types with sizes that
overflow the ioctl number. Mark them _IOx_BAD() to document the fact.

This new version works with all compiler versions, and also catches the
case where somebody tries to pass in an array as an argument to the
ioctl macros.  Thus we verify that only proper types are used.

I have checked now that the object code for arch/s390/kernel/compat_ioctl.o
remains identical and that the whole kernel compiles for s390 and i386,
after fixing the broken ioctl numbers.

The kernel invokes "modprobe" on modules which might not exist:
rightfully, modprobe complains by default when this happens.  So the
correct response is to invoke "modprobe -q", which is silent on such
errors (but still reports other errors such as config errors). 

Also, use MODULE_NAME_LEN from module.h instead of inventing our own.

Someone pointed out that -ffunction-sections can cause a function called
"init<something>" to be put in the init section, and discarded.  This
hurts PARISC badly.  Get more fussy with identifying them.

This adds CONFIG_64BIT to allow us to disable non-64-bit safe drivers on
64-bit platforms and converts the I2O driver to use it.

Nothing too exciting, just some minor new features and bug fixes.
The IOMMU code should now not BUG again without CONFIG_IOMMU_DEBUG/iommu=force

 - Compiles now with -funit-at-a-time
 - Fix up ioctl 32bit tables following Andrew's change.
 - Fix __SI_POLL siginfo_t passing to user space
 - Add 32bit emulation for fadvise64_64
 - Remove unneeded sys32_utimes
 - Various merges with i386 (ACPI, APIC etc.)
 - Port cpuid patching infrastructure from i386
 - Use it to provide better copy_*_user/memcpy/memset/clear/copy_page for
   C stepping K8. String instructions are faster now that unrolled loops.
 - Don't try to merge unforced PCI mappings that don't exceed the device's
   DMA mask.
 - Discard .exit.data/.exit.text at runtime like i386
 - Don't use NTI stores for clear_user
 - Convert bitops.h bitmap functions to use unsigned long * pointers instead
   of void *
 - Fix some warnings in kernel headers.
 - Fix PDA comments

Not much to write home about. mostly tidying, some debug, and XIP support.

just keeping arm26 up to date really.

[ "carbonated beverage"? WTF? I think I need a cool handle too ;]

In addition to the MODULE_ALIAS_LDISC patch, the following changes to
generic code are needed to allow ARM to build in Linus' tree.

The first is to add PT_SINGLESTEP to ptrace.h so we do the right thing
when adding/removing breakpoint instructions into processes (see
arch/arm/kernel/{signal.c,ptrace.c} for usage.)

The second is needed because pmd_clear() needs to flush the pmd.
However, we can't include tlbflush.h into pgtable.h without causing
a circular dependency (tlbflush.h needs vm_area_struct and mm_struct
which are in mm.h, which needs pgtable.h.)  swapfile.c seems to be the
only file affected.

here are the next fixes, sorry for the delay, but one of bugs was a really
odd one.

Note:
- here are lot of bugs left, so ISDN is not stable yet but
  I think it's really time to fix it, even if it need some cycles
  to get it right (normally I'm only send patches if it works 100% for
  me).
- I add some additional #warnings to address places which need fixing
  (I hope that some of the other ISDN developer jump in)
