Via irq routing has a funky PIRQD location.  I checked my datasheets
and, yep, this is correct all the way back to via686a.
This bug existed for _ages_.  I wonder if I created it, even...

follow by splitting it into two functions: one that calculates
the position, and the other that actually reads the inode
block off the disk.

uses it for now, but I needed it for some tuning tests,
and it is potentially useful for others.

This patch fixes a bad declaration of jiffies in timer_tsc.c and
timer_cyclone.c, replacing it with the proper usage of jiffies.h.

This patch corrects a trivial thinko in the manual resource api.

This patch updates the resource manager so that it actually assigns
disabled resources when they are requested by the device.

Some devices will allow for individual resources to be disabled,
even when the device as a whole is active.  The current PnP
resource manager is not handling this situation properly.  This
patch corrects the issue by detecting disabled resources and then
flagging them. The pnp layer will now skip over any disabled 
resources.  Interface updates have also been included so that we
can properly display resource tables when a resource is disabled.

Also note that a new flag "IORESOURCE_DISABLED" has been added to
linux/ioports.h.

Fixes the sysfs binary file bug.

 - Fix a couple of bugs in sysfs's handling of binary files (my fault).
 - Implement pci config space reads and writes in sysfs

Make pcibios_fixup_peer_bridges() use raw_pci_ops directly instead of
faking pci_bus and pci_dev.

Use pci_find_bus rather than relying on the return value of pci_scan_bus.

Convert all callers of pci_bus_exists() to call pci_find_bus() instead.
Since all callers of pci_find_bus() are __init or __devinit, mark it as
__devinit too.

Give pci_find_bus a domain argument and move its declaration to <linux/pci.h>

pci_sanity_check() is only called from functions marked __init, so it
can be __init too.

Fix some grammar problems
Add a note about Fast Back to Back support
Change the slot_name recommendation to pci_name().

used to work due to some random magic indirect include, but broke lately.

Do the obvious fix.

This moves the ksoftirqd pointers out of the irq_stat struct, and uses a
normal per-cpu variable.  It's not that time critical, nor referenced in
assembler.  This moves us closer to making irq_stat a per-cpu variable.

Because some archs have hardcoded asm references to offsets in this
structure, I haven't touched non-x86.  The __ksoftirqd_task field is
unused in other archs, too.

Noone seems to use __syscall_count.  Remove the field from i386
irq_cpustat_t struct, and the generic accessor macros.

Because some archs have hardcoded asm references to offsets in this
structure, I haven't touched non-x86, but doing so is usually
trivial.

Rather trivial conversion.  Tested on SMP.

The function cpu_raise_softirq() takes a softirq number, and a cpu number,
but cannot be used with cpu != smp_processor_id(), because there's no
locking around the pending softirq lists.  Since noone does this, remove
that arg.

As per Linus' suggestion, names changed:
	raise_softirq(int nr)
	cpu_raise_softirq(int cpu, int nr) -> raise_softirq_irqoff(int nr)
	__cpu_raise_softirq(int cpu, int nr) -> __raise_softirq_irqoff(int nr)

I though Scott had recently merged this but it seems not.  We'll be
needing this patch if you merge Manfred's page unmapping debug patch.

Attached patch adds a range check to LOG_BUF_SHIFT and clarifies the
configuration somewhat.  I managed to build a non-booting kernel because I
thought 64 was a nice power of two, which lead to the kernel blocking when
it tried to actually use or allocate a 2^64 buffer.

		CPU0				CPU1

	journal_get_write_access(bh)
	 (Add buffer to t_reserved_list)

					journal_get_write_access(bh)
					 (It's already on t_reserved_list:
					  nothing to do)

	 (We decide we don't want to
	  journal the buffer after all)
	journal_release_buffer()
	 (It gets pulled off the transaction)


					journal_dirty_metadata()
					 (The buffer isn't on the reserved
					  list!  The kernel explodes)


Simple fix: just leave the buffer on t_reserved_list in
journal_release_buffer().  If nobody ends up claiming the buffer then it will
get thrown away at start of transaction commit.

If load_elf_binary() (and the other binary handlers) fail after
flush_old_exec() (for example, in setup_arg_pages()) then do_execve() will go
through and do mmdrop(bprm.mm).

But bprm.mm is now current->mm.  We've just freed the current process's mm.
The kernel dies in a most ghastly manner.

Fix that up by nulling out bprm.mm in flush_old_exec(), at the point where we
consumed the mm.  Handle the null pointer in the do_execve() error path.

Also: don't open-code free_arg_pages() in do_execve(): call it instead.

ext2's inode allocator will call find_group_orlov(), which will return a
suitable blockgroup in which the inode should be allocated.  But by the time
we actually try to allocate an inode in the blockgroup, other CPUs could have
used them all up.

ext2 will bogusly fail with "ext2_new_inode: Free inodes count corrupted in
group NN".


To fix this we just advance onto the next blockgroup if the rare race
happens.  If we've scanned all blockgroups then return -ENOSPC.


(This is a bit inaccurate: after we've scanned all blockgroups, there may
still be available inodes due to inode freeing activity in other blockgroups.
 This cannot be fixed without fs-wide locking.  The effect is a slightly
early ENOSPC in a nearly-full filesystem).

This patch against 2.5.73 replaces vm_enough_memory with a security hook
per Alan Cox's suggestion so that security modules can completely replace
the logic if desired.

Note that the patch changes the interface to follow the convention of the
other security hooks, i.e.  return 0 if ok or -errno on failure (-ENOMEM in
this case) rather than returning a boolean.  It also exports various
variables and functions required for the vm_enough_memory logic.

This patch allows architectures to micro-optimize lowmem_page_address() at
their whims.  Roman Zippel originally wrote and/or suggested this back when
dependencies on page->virtual existing were being shaken out.  That's
long-settled, so it's fine to do this now.

From: john stultz <johnstul@us.ibm.com>

This patch catches a corner case in the lost-tick compensation code.

There is a check to see if we overflowed between reads of the two time
sources, however should the high res time source be slightly slower then
what we calibrated, its possible to trigger this code when no ticks have
been lost.

This patch adds an extra check to insure we have seen more then one tick
before we check for this overflow.  This seems to resolve the remaining
"time doubling" issues that I've seen reported.
