This patch adds a mutex to the e1000e driver that would help
catch any collisions of two e1000e threads accessing hardware
at the same time.

e1000e was apparently calling two functions that attempted to reserve
the SWFLAG bit for exclusive (to hardware and firmware) access to
the PHY and NVM (aka eeprom). These accesses could possibly call
msleep to wait for the resource which is not allowed from interrupt

When we initialise a compound page we initialise the page flags and head
page pointer for all base pages spanned by that page. When we initialise
a gigantic page (a page of order greater than or equal to MAX_ORDER) we
have to initialise more than MAX_ORDER_NR_PAGES pages. Currently we
assume that all elements of the mem_map in this page are contigious in
memory. However this is only guarenteed out to MAX_ORDER_NR_PAGES pages,
and with SPARSEMEM enabled they will not be contigious. This leads us to
walk off the end of the first section and scribble on everything which
follows, BAD.
When we reach a MAX_ORDER_NR_PAGES boundary we much locate the next
section of the mem_map. As gigantic pages can only be maximally aligned
we know this will occur at exact multiple of MAX_ORDER_NR_PAGES pages from
the start of the page.
This is a bug fix for the gigantic page support in hugetlbfs.

The previous patch db203d53d4 ("mm:
tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock
ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU
architectures because it was using the expanding truncate to signal ramfs
to allocate a physically contiguous RAM backing the inode (otherwise it is
unusable for "memory mapping" it to userspace).
However do_truncate is what caused the lock ordering error, due to it
taking i_mutex. In this case, we can actually just call ramfs directly to
allocate memory for the mapping, rather than go via truncate.

__test_page_isolated_in_pageblock() in mm/page_isolation.c has a comment
saying that the caller must hold zone->lock. But the only caller of that
function, test_pages_isolated(), does not hold zone->lock and the lock is
also not acquired anywhere before. This patch adds the missing zone->lock
to test_pages_isolated().
We reproducibly run into BUG_ON(!PageBuddy(page)) in __offline_isolated_pages()
during memory hotplug stress test, see trace below. This patch fixes that
problem, it would be good if we could have it in 2.6.27.

Commit 00c5372d37 caused the MPC8544DS
board to hang at boot. The MPC8544DS is unique in that it doesn't use
the PCI slots on the ULI (unlike the MPC8572DS or MPC8610HPCD). So
the dummy read at the end of the address space causes us to hang.
We can detect the situation by comparing the bridge's BARs versus

Checksum items take up a significant portion of the metadata for large files.
It is possible to avoid reading them during truncates by checking the keys in
the higher level nodes.
If a given leaf is followed by another leaf where the lowest key is a checksum
item from the same file, we know we can safely delete the leaf without
reading it.
For a 32GB file on a 6 drive raid0 array, Btrfs needs 8s to delete
the file with a cold cache. It is read bound during the run.
With this change, Btrfs is able to delete the file in 0.5s

This fixes a deadlock that happens between the alloc_mutex and chunk_mutex.
Process A comes in, decides to do a do_chunk_alloc, which takes the
chunk_mutex, and is holding the alloc_mutex because the only way you get to
do_chunk_alloc is by holding the alloc_mutex. btrfs_alloc_chunk does its thing
and goes to insert a new item, which results in a cow of the block.
We get into del_pending_extents from there, where if we need to be rescheduled
we drop the alloc_mutex and schedule. At this point process B comes in to do
an allocation and gets the alloc_mutex, and because process A did not do the
chunk allocation completely it thinks its a good time to do a chunk allocation
as well, and hangs on the chunk_mutex.
Process A wakes up and tries to take the alloc_mutex and cannot. The way to
fix this is do a mutex_trylock() on chunk_mutex. If we return 0 we didn't get
the lock, and if this is just a "hey it may be a good time to allocate a chunk"
then we just exit. If we are trying to force an allocation then we reschedule
and keep trying to acquire the chunk_mutex. If once we acquire it the space is
already full then we can just exit, otherwise we can continue with the chunk
allocation. Thank you,

Fix the IRQ handling on the MN10300 arch.
This patch makes a number of significant changes:
(1) It separates the irq_chip definition for edge-triggered interrupts from
the one for level-triggered interrupts.
This is necessary because the MN10300 PIC latches the IRQ channel's
interrupt request bit (GxICR_REQUEST), even after the device has ceased to
assert its interrupt line and the interrupt channel has been disabled in
the PIC. So for level-triggered interrupts we need to clear this bit when
we re-enable - which is achieved by setting GxICR_DETECT but not
GxICR_REQUEST when writing to the register.
Not doing this results in spurious interrupts occurring because calling
mask_ack() at the start of handle_level_irq() is insufficient - it fails
to clear the REQUEST latch because the device that caused the interrupt is
still asserting its interrupt line at this point.
(2) IRQ disablement [irq_chip::disable_irq()] shouldn't clear the interrupt
request flag for edge-triggered interrupts lest it lose an interrupt.
(3) IRQ unmasking [irq_chip::unmask_irq()] also shouldn't clear the interrupt
request flag for edge-triggered interrupts lest it lose an interrupt.
(4) The end() operation is now left to the default (no-operation) as
__do_IRQ() is compiled out. This may affect misrouted_irq(), but
according to Thomas Gleixner it's the correct thing to do.
(5) handle_level_irq() is used for edge-triggered interrupts rather than
handle_edge_irq() as the MN10300 PIC latches interrupt events even on
masked IRQ channels, thus rendering IRQ_PENDING unnecessary. It is
sufficient to call mask_ack() at the start and unmask() at the end.
(6) For level-triggered interrupts, ack() is now NULL as it's not used, and
there is no effective ACK function on the PIC. mask_ack() is now the
same as mask() as the latch continues to latch, even when the channel is
masked.
Further, the patch discards the disable() op implementation as its now the same
as the mask() op implementation, which is used instead.
It also discards the enable() op implementations as they're now the same as
the unmask() op implementations, which are used instead.

dm mpath: add missing path switching locking
dm: cope with access beyond end of device in dm_merge_bvec
dm: always allow one page in dm_merge_bvec
Moving the path activation to workqueue along with scsi_dh patches introduced
a race. It is due to the fact that the current_pgpath (in the multipath data
structure) can be modified if changes happen in any of the paths leading to
the lun. If the changes lead to current_pgpath being set to NULL, then it
leads to the invalid access which results in the panic below.
This patch fixes that by storing the pgpath to activate in the multipath data
structure and properly protecting it.
Note that if activate_path is called twice in succession with different pgpath,
with the second one being called before the first one is done, then activate
path will be called twice for the second pgpath, which is fine.

When reading in block groups, a global mask of the available raid policies
should be adjusted based on the types of block groups found on disk. This
global mask is then used to decide which raid policy to use for new
block groups.
The recent allocator changes dropped the call that updated the global
mask, making all the block groups allocated at run time single striped
onto a single drive.
This also fixes the async worker threads to set any thread that uses
the requeue mechanism as busy. This allows us to avoid blocking

This patch fixes a problem where we end up seeking too much when *last_ptr is
valid. This happens because btrfs_lookup_first_block_group only returns a
block group that starts on or after the given search start, so if the
search_start is in the middle of a block group it will return the block group
after the given search_start, which is suboptimal.
This patch fixes that by doing a btrfs_lookup_block_group, which will return
the block group that contains the given search start. If we fail to find a
block group, we fall back on btrfs_lookup_first_block_group so we can find the
next block group, not sure if this is absolutely needed, but better safe than
sorry.
Also if we can't find the block group that we need, or it happens to not be of
the right type, we need to add empty_cluster since *last_ptr could point to a
mismatched block group, which means we need to start over with empty_cluster
added to total needed. Thank you,
