extended config-space addresses when needed.  This avoids
	the fragile SAL version testing.

Currently set_rte() changes RTE without iosapic_lock held. I guess it
assumes to be called only at the boot time. But set_rte() can be
called by PCI driver not only at the boot time. So I think set_rte()
should get iosapic_lock.

A following patch fixes this issue.

Some firmware does not require run-time mapping of the legacy IO port
space.  (It may not need to perform any IO port operations, or it may
do them with translation disabled.)

(efi_get_iobase): Don't require that IO port space be marked RT, since
there's no reason the firmware should require mappings for it.
Thanks to Greg Albrecht for noticing this.

Also, allow attributes in addition to EFI_MEMORY_UC.  I can't
think of another current attribute that makes sense, but the
kernel only depends on being able to use UC.

	mismatch because the external declaration isn't in the arch-
	independent ACPI bits yet.

Here is a new perfmon patch. It is important because it
fixes the problem of the close() when the file descriptor
is shared between two related processes. The good thing
is that it simplifies a lot the cleanup of the sampling
buffer.

Here is the ChangeLog:

- fix bug in pfm_close() when the descriptor is
  shared between related processed. Introduce
  a pfm_flush() called for each invocation of
  close(). pfm_close() only called for the last
  user.

- fix pfm_restore_monitoring() to also reload
  the debug registers. They could be modified
  while monitoring is masked.

- fix pfm_close() to clear ctx_fl_is_sampling.

- fix a bug in pfm_handle_work() which could cause
  the wrong PMD to be reset. 

- converted PROTECT_CTX/UNPROTECT_CTX into
  local_irq_save/restore to keep context protection
  but allow IPI to proceed.

- updated pfm_syswide_force_stop() to use
  local_irq_save/restore now that the context
  is protected from the caller side.

- updated pfm_mck_pmc_check() to check if context is 
  loaded before checking for special IBR/DBR combinations.
  Clearing the debug registers is not needed when the context
  is not yet loaded.

- updated perfmon.h to have to correct prototype definitions
  for the pfm_mod_*() functions.

- got rid of the PFM_CTX_TERMINATED state.

- cleanup the DPRINT() statements to remove
  explicit output of current->pid. This is done
   systematically by the macros.

- added a systctl entry (expert_mode) to bypass
  read/write checks on PMC/PMD. As its name indicates
  this is for experts ONLY. Must be root to toggle
  /proc/sys entry.

- corrected pfm_mod_*() to check against the current task.

- removed pfm_mod_fast_read_pmds(). It is never needed.

- added pfm_mod_write_ibrs() and pfm_mod_write_dbrs().

Requiring CONFIG_HP_SIMSCSI to be either  "y" or "n" breaks
allmodconfig, because simscsi ends up built-in, while scsi itself
is a module.  So allow simscsi to be a module also.

Here's the ia64 part of the ACPI IRQ cleanup I proposed here:

http://www.gelato.unsw.edu.au/linux-ia64/0403/8979.html

After the arch bits are in, I'll post the corresponding ACPI changes.
I removed the "Found IRQ" printk now because when the ACPI
change goes in, dev->irq won't be initialized until *after*
acpi_pci_irq_enable().

sba_iommu was setting up MAX_DMA_ADDRESS way too late to do any
good.  This patch makes it get setup via platform_setup, so it's ready
for paging_init().  All pages should show up in zone DMA now.  Against
latest 2.6.

This fixes a missing include file in arch/ia64/mm/hugetlbpage.c in 2.6.5.
module.h is needed for EXPORT_SYMBOL.

Calling mmap with len == -1 was silently accepted.  The test in the generic
code was fixed in July 2003, but the fix didn't make it into the ia64-
specific code.

We default to "long" (which is what POSIX says), but since
a number of architectures have used "int" for historical
reasons, we need to allow overrides.

At least sparc64 needs this. Possibly others, but so far
architecture maintainers haven't spoken up. ppc64 and x86-64
are known to be ok with the default "long".

When I was updating ppc/boot/simple/relocate.S to work on PPC_PREP systems, I
in advertantly broke 4xx systems.  On classic PPC, the first three
instructions are nops, of which the first two can be overwritten.  This is
not true of 4xx (or 8xx, but that's not working right now anyhow).  The
following is needed to fix this.

The commoncap module calls this.

- Use -march=armv6 where available.
- CFLAGS_BOOT isn't needed - the decompressor uses CFLAGS, remove it.
- PROCESSOR is never used, remove it.
- LDFLAGS_BLOB is never used, remove it.
- Remove MACHINE macro.
- Correct comments for include/asm-arm/.arch target.
- Copy format of include/asm symlink rule.
- Arrange for configuration to be split before making
  include/asm-arm/arch symlink.
- This means that asm-offsets.s no longer depends on
  include/config/MARKER.

diva_os_cancel_soft_isr() may not call tasklet_kill(), because it is
interrupt context.  This will be done correctly in the cleanup function
anyway.

The patch to check "maxcpus=N" early broke by putting maxcpus (a
variable which is only exported by mpparse.c) into
parse_cmdline_early().

The fix is to make it depend on the correct CONFIG_ option. 

In the subarchitectures:

CONFIG_X86_SMP is the one that means "I want standard x86 smp code" and
that's what this should depend on.

This patch from Christoph Hellwig does much welcomes cleanup of
the old mac53c94 and mesh SCSI drivers, removing sillycaps etc...

Andi's libnuma exposed the fact that we don't bring nodes online
properly as we discover them in ia64.  Here's a quick patch to fix
that.  Tested with Andi's numademo program; seems to work fine.

This fixes a problem in sys_swapon that can cause the creation of invalid
swap ptes.  This has its cause in the arch-independent swap entries vs. 
the pte coded swap entries.  The swp_entry_t uses 27 bits for the offset
and 5 bits for the type.  In sys_swapon this definition is used to find how
many swap devices and how many pages on each device there can be.  But the
swap entries encoded in a pte can be subject to additional restrictions due
to the hardware besides the 27/5 division of the bits in the swp_entry_t
type.  This is solved by adding pte_to_swp_entry and swp_entry_to_pte calls
to the calculations for maximum type and offset.

In addition the s390 swap pte division for offset/type is changed from 19/6
bits to 20/5 bits.
