Fix a bug in udf where it would write uid/gid = 0 to the disk for files
owned by the id given with the uid=/gid= mount options. It also adds 4 new
mount options: uid/gid=forget and uid/gid=ignore. Without any options the
id in core and on disk always match. Giving uid/gid=nnn specifies a
default ID to be used in core when the on disk ID is -1. uid/gid=ignore
forces the in core ID to allways be used no matter what the on disk ID is.
uid/gid=forget forces the on disk ID to always be written out as -1.
The use of these options allows you to override ownerships on a disk or
disable ownwership information from being written, allowing the media to be
used portably between different computers and possibly different users
without permissions issues that would require root to correct.

We're presently getting oopses because Bluetooth (and possibly other) drivers
are calling core functions after things have been shut down.
So rather than oopsing, let's drop a warning then take avoiding action, so the
machine survives. Once all the sub-drivers are fixed up we can remove the
take-avoiding-action part.

Turn on CONFIG_PNPACPI. I recently removed 8250_acpi.c. All devices
previously claimed by 8250_acpi.c should now be claimed by 8250_pnp.c.
This depends on having CONFIG_PNPACPI so ACPI devices show up as PNP
devices.
All other ia64 defconfigs either have CONFIG_PNPACPI already, or
don't have 8250 support turned on at all.

The MCA recovery messages are currently KERN_DEBUG,
so they don't show up in /var/log/messages (by default).
Increase the severity to KERN_ERR, for the initial

KERN_DEBUG, but increase the severity when isolation
fails to KERN_CRIT.

Patch from Catalin Marinas
Chapter B2.7.3 in the latest ARM ARM (with v6 information) states that
the completion of a TLB maintenance operation is only guaranteed by
the execution of a DSB (Data Syncronization Barrier, formerly Data
Write Barrier or Drain Write Buffer).
Note that a DSB is only needed in the flush_tlb_kernel_* functions
since the completion is guaranteed by a mode change (i.e. switching
back to user mode) for the flush_tlb_user_* functions.

Add DMA workaround for chips that do not support full 64-bit DMA
addresses.
5714, 5715, and 5780 chips only support DMA addresses less than 40
bits. On 64-bit systems with IOMMU, set the dma_mask to 40-bit so
that pci_map_xxx() calls will map the DMA address below 40 bits if
necessary. On 64-bit systems without IOMMU, set the dma_mask to
64-bit and check for DMA addresses exceeding the limit in
tg3_start_xmit().
5788 only supports 32-bit DMA so need to set the mask appropriately
also.
Thanks to Chris Elmquist at SGI for reporting and helping to debug
the problem on 5714.

The point of the smaps "shared" is to count the number of pages that are
mapped by more than one process, according to Mauricio Lin. However, smaps
uses page_count for this, so it will return a false positive for every page
that is mapped by just that one process, which is also in pagecache or
swapcache. There are false positive situations for anonymous pages not in
swapcache as well: - page reclaim, migration - get_user_pages (eg.
direct-io, ptrace)
Use page_mapcount instead, to count the number of mappings to the page.
Use vm_normal_page so that weird things like /dev/mem aren't counted either.

ramfs neglects to update the directory mtime and ctime fields when creating
a new symbolic link. Ramfs was modified in 2.6.15 to update these fields
when other types of entries are created. The symlink support is separate
from that other support, so that change did not cover quite all of the
possibilities.
All of the directory content manipulation entry points now seem to be
covered with respect to these time field updates.

Change the format of numa_maps to be more compact and contain additional
information that is useful for managing and troubleshooting memory on a
NUMA system. Numa_maps can now also support huge pages.
Fixes:
1. More compact format. Only display fields if they contain additional
information.
2. Always display information for all vmas. The old numa_maps did not display
vma with no mapped entries. This was a bit confusing because page
migration removes ptes for file backed vmas. After page migration
a part of the vmas vanished.
3. Rename maxref to maxmap. This is the maximum mapcount of all the pages
in a vma and may be used as an indicator as to how many processes
may be using a certain vma.
4. Include the ability to scan over huge page vmas.
New items shown:
dirty
Number of pages in a vma that have either the dirty bit set in the
page_struct or in the pte.
file=<filename>
The file backing the pages if any
stack
Stack area
heap
Heap area
huge
Huge page area. The number of pages shows is the number of huge
pages not the regular sized pages.
swapcache
Number of pages with swap references. Must be >0 in order to
be shown.
active
Number of active pages. Only displayed if different from the number
of pages mapped.
writeback
Number of pages under writeback. Only displayed if >0.
Sample ouput of a process using huge pages:

Also from Thomas Gleixner <tglx@linutronix.de>
Function next_timer_interrupt() got broken with a recent patch
6ba1b91213e81aa92b5cf7539f7d2a94ff54947c as sys_nanosleep() was moved to
hrtimer. This broke things as next_timer_interrupt() did not check hrtimer
tree for next event.
Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ,
VST) implementations, as the system can be in idle when next hrtimer event
was supposed to happen. At least ARM and S390 currently use
next_timer_interrupt().

Just to be safe, we should not trigger a conditional reschedule during
