find_next_system_ram() is used to find available memory resource at onlining
newly added memory. This patch fixes following problem.
find_next_system_ram() cannot catch this case.
Resource: (start)-------------(end)

find_next_system_ram() returns valid memory range which meets requested area,
only used by memory-hot-add.
This function always rewrite requested resource even if returned area is not
fully fit in requested one. And sometimes the returnd resource is larger than
requested area. This annoyes the caller. This patch changes the returned
value to fit in requested area.

ioresouce handling code in memory hotplug allows not-aligned memory hot add.
But when memmap and other memory structures are initialized, parameters should
be aligned. (if not aligned, initialization of mem_map will do wrong, it
assumes parameters are aligned.) This patch fix it.
And this patch allows ioresource collision check to handle -EEXIST.

In bugzilla #6941, Jens Kilian reported:
"The function befs_utf2nls (in fs/befs/linuxvfs.c) writes a 0 byte past the
end of a block of memory allocated via kmalloc(), leading to memory
corruption. This happens only for filenames which are pure ASCII and a
multiple of 4 bytes in length. [...]
Without DEBUG_SLAB, this leads to further corruption and hard lockups; I
believe this is the bug which has made kernels later than 2.6.8 unusable
for me. (This must be due to changes in memory management, the bug has
been in the BeFS driver since the time it was introduced (AFAICT).)
Steps to reproduce:
Create a directory (in BeOS, naturally :-) with files named, e.g.,
"1", "22", "333", "4444", ... Mount it in Linux and do an "ls" or "find""
This patch implements the suggested fix. Credits to Jens Kilian for
debugging the problem and finding the right fix.

At least Maxtor OneTouch III require a "start stop unit" command after auto
spin-down before the next access can proceed. This patch activates the
responsible code in scsi_mod for all Maxtor SBP-2 disks.
https://bugzilla.novell.com/show_bug.cgi?id=183011
Maybe that should be done for all SBP-2 disks, but better be cautious.

While helping someone to submit a patch to the stable branch, I noticed
that the stable branch is not listed in the MAINTAINERS file. This was
after I went there to look for the email addresses for the stable branch
list (stable@kernel.org).
This patch adds the stable branch to the maintainers file so that people
can find where to send patches when they have a fix for the stable team.

A set of tty line discipline cleanup patches were introduced before the
dawn of time, in kernel version 2.4.21. This patch performs that cleanup
for the hvsi driver.
The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was
originally written by Hollis Blanchard, who has delegated maintainership to
me. So this my first and maybe only patch in this official new role,
because this driver is otherwise bug-free :-)

cache
If we don't find the item we are lookng for, we allocate a new one, and
then grab the lock again and search to see if it has been added while we
did the alloc. If it had been added we need to 'cache_put' the newly
created item that we are never going to use. But as it hasn't been
initialised properly, putting it can cause an oops.
So move the ->init call earlier to that it will always be fully initilised
if we have to put it.

The POSIX_FADV_NOREUSE hint means "the application will use this range of the
file a single time". It seems to be intended that the implementation will use
this hint to perform drop-behind of that part of the file when the application
gets around to reading or writing it.
However for reasons which aren't obvious (or sane?) I mapped
POSIX_FADV_NOREUSE onto POSIX_FADV_WILLNEED. ie: it does readahead.
That's daft. So for now, make POSIX_FADV_NOREUSE a no-op.
This is a non-back-compatible change. If someone was using POSIX_FADV_NOREUSE
to perform readahead, they lose. The likelihood is low.
If/when we later implement POSIX_FADV_NOREUSE things will get interesting - to
do it fully we'll need to maintain file offset/length ranges and peform all
sorts of complex tricks, and managing the lifetime of those ranges' data
structures will be interesting..
A sensible implementation would probably ignore the file range and would
simply mark the entire file as needing some form of drop-behind treatment.

This can occur when release_console_sem() is called but the log
buffer still has contents that need to be flushed. The console drivers
are called while the console_may_schedule flag is still true. The
might_sleep() is triggered when fbcon calls console_conditional_schedule().
Fix by setting console_may_schedule to zero earlier, before the call to the
console drivers.

ufs_get_locked_page is called twice in ufs code, one time in ufs_truncate
path(we allocated last block), and another time when fragments are
reallocated. In ideal world in the second case on allocation/free block
layer we should not know that things like `truncate' exists, but now with
such crutch like ufs_get_locked_page we can (or should?) skip truncated
pages.

As discussed earlier:
http://lkml.org/lkml/2006/6/28/136
this patch fixes such issue:
`ufs_get_locked_page' takes page from cache
after that `vmtruncate' takes page and deletes it from cache
`ufs_get_locked_page' locks page, and reports about EIO error.
Also because of find_lock_page always return valid page or NULL, we have no
need to check it if page not NULL.

404: R_390_PC32DBL _spin_lock+0x2
/* use r2 as parameter for spin_lock */
So the code becomes more or less:
if (q->lock_ptr != 0) spin_lock(q->lock_ptr)
instead of
if (lock_ptr != 0) spin_lock(lock_ptr)
Which caused the oops from above.
After adding a barrier gcc creates code without this problem:
[...] (the same)
3ee: e3 c0 b0 28 00 04 lg %r12,40(%r11)
3f4: b9 02 00 cc ltgr %r12,%r12
3f8: b9 04 00 2c lgr %r2,%r12

400: c0 e5 00 00 00 00 brasl %r14,400 <unqueue_me+0x38>
402: R_390_PC32DBL _spin_lock+0x2
As a general note, this code of unqueue_me seems a bit fishy. The retry logic
of unqueue_me only works if we can guarantee, that the original value of
q->lock_ptr is always a spinlock (Otherwise we overwrite kernel memory). We
know that q->lock_ptr can change. I dont know what happens with the original
spinlock, as I am not an expert with the futex code.

It should be possible to suspend, either to RAM or to disk, if there's a
traced process that has just reached a breakpoint. However, this is a
special case, because its parent process might have been frozen already and
then we are unable to deliver the "freeze" signal to the traced process.
If this happens, it's better to cancel the freezing of the traced process.

[IA64] make uncached allocator more node aware
|
|
The uncached allocator has a function, uncached_get_new_chunk(), that needs
to be serialized on a per node basis. It also has a global variable,
allocated_granules, which should be defined on a per node basis and protected
by that serialization. Additionally, all error returns from functions called
(like ia64_pal_mc_drain()) should be handled appropriately.

Skip protocol test altogether in spurious interrupt code. If PIOS is received

When writing the firmware to the NIC, the FIFO is 256-bytes long,
so we use 256-bytes chunks and a read to wait until the previous

Prevent phylib from freeing PHY IRQ twice on closing an eth device:
phy_disconnect() first calls phy_stop_interrupts(), then it calls
phy_stop_machine() which in turn calls phy_stop_interrupts() making the
kernel complain on each bootup...

This patch contains some of the bug fixes and enhancements done to
s2io driver. Following are the brief description of changes
1. code cleanup to handle gso modification better
2. Move repeated code in rx path, to a common function
s2io_chk_rx_buffers()
3. Bug fix in MSI interrupt
4. clear statistics when card is down
5. Avoid linked list traversing in lro aggregation.
6. Use pci_dma_sync_single_for_cpu for buffer0 in case of 2/3
buffer mode.
7. ethtool tso get/set functions to set clear NETIF_F_TSO6
8. Stop LRO aggregation when we receive ECN notification

This patch contains some of the bug fixes and enhancements done to
s2io driver. Following are the brief description of changes
1. Introduced macro "S2IO_PARM_INT" for declaring integer load parameter
2. UDP_RR test failure, memset txdl after Tx completion
3. PXE boot may leave adapter in unknown state so do reset in probe.
4. Add Tx completion code in netpoll
5. In s2io_vpd_read() move array vpd_data[] to pointer, saves stack memory
6. Fix bug in ethtool online test
