move stk17ta8's probe function to .devinit.text
A pointer to stk17ta8_rtc_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an

platform_driver_register plus removing the pointer to the probe function

ataflop: remove buggy/commented-out IRQ disable from do_fd_request()
There is a nice gem in drivers/block/ataflop.c::do_fd_request()
void do_fd_request(struct request_queue * q)
{
unsigned long flags;
DPRINT(("do_fd_request for pid %d\n",current->pid));
while( fdc_busy ) sleep_on( &fdc_wait );
fdc_busy = 1;
stdma_lock(floppy_irq, NULL);
atari_disable_irq( IRQ_MFP_FDC );

local_irq_disable(); * disabled... so must save the IPL for later */
redo_fd_request();
local_irq_restore(flags);
atari_enable_irq( IRQ_MFP_FDC );
}
If you look at the code long enough, you will notioce that the
local_irq_disable() call is actually commented out. This has been
introduced back in 2002 in [1], but as you can see, the same bug has been
there even before, with the sti() call being commented out in the very
same way :)
I am not familiar with the code myself at all, but I guess that the whole
stuff can just be removed. Why do we need save_flags/restore_flags at all,
without actually disabling the local IRQs afterwards? The
redo_fd_request() doesn't seem to do anything that would mess with flags
inconsistently.
[1] http://lkml.org/lkml/2002/12/27/58
Jens:
That does look odd. The comment is correct that the function is entered
with interrupts disabled (and the queue lock held). So I'd say your
patch looks fine, the whole save/restore business looks meaningless.

x86: Make sure get_user_desc() doesn't sign extend.
The current implementation of get_user_desc() sign extends the return
value because of integer promotion rules. For the most part, this
doesn't matter, because the top bit of base2 is usually 0. If, however,
that bit is 1, then the entire value will be 0xffff... which is
probably not what the caller intended.
This patch casts the entire thing to unsigned before returning, which
generates almost the same assembly as the current code but replaces the
final "cltq" (sign extend) with a "mov %eax %eax" (zero-extend). This
fixes booting certain guests under KVM.

a reads a sector s and goes to idle window and wakeup b. b reads sector
s+1, since in current implementation, cfq_should_preempt() thinks a and

Correct nr_processes() when CPUs have been unplugged
nr_processes() returns the sum of the per cpu counter process_counts for
all online CPUs. This counter is incremented for the current CPU on
fork() and decremented for the current CPU on exit(). Since a process
does not necessarily fork and exit on the same CPU the process_count for
an individual CPU can be either positive or negative and effectively has
no meaning in isolation.
Therefore calculating the sum of process_counts over only the online
CPUs omits the processes which were started or stopped on any CPU which
has since been unplugged. Only the sum of process_counts across all
possible CPUs has meaning.
The only caller of nr_processes() is proc_root_getattr() which
calculates the number of links to /proc as
stat->nlink = proc_root.nlink + nr_processes();
You don't have to be all that unlucky for the nr_processes() to return a
negative value leading to a negative number of links (or rather, an
apparently enormous number of links). If this happens then you can get
failures where things like "ls /proc" start to fail because they got an
-EOVERFLOW from some stat() call.
Example with some debugging inserted to show what goes on:
# ps haux|wc -l

nr_processes: CPU1: 1030
nr_processes: CPU2: -900
nr_processes: CPU3: -136

I'm not 100% convinced that the per_cpu regions remain valid for offline
CPUs, although my testing suggests that they do. If not then I think the
correct solution would be to aggregate the process_count for a given CPU
into a global base value in cpu_down().
This bug appears to pre-date the transition to git and it looks like it
may even have been present in linux-2.6.0-test7-bk3 since it looks like
the code Rusty patched in http://lwn.net/Articles/64773/ was already

There are too many retval variables in save_image(). Thus error return
value from snapshot_read_next() may be ignored and only part of the
snapshot (successfully) written.
Remove 'error' variable, invert the condition in the do-while loop
and convert the loop to use only 'ret' variable.
Switch the rest of the function to consider only 'ret'.
Also make sure we end printed line by \n if an error occurs.

PM / Hibernate: Fix blkdev refleaks
While cruising through the swsusp code I found few blkdev reference
leaks of resume_bdev.
swsusp_read: remove blkdev_put altogether. Some fail paths do
not do that.
swsusp_check: make sure we always put a reference on fail paths
software_resume: all fail paths between swsusp_check and swsusp_read
omit swsusp_close. Add it in those cases. And since
swsusp_read doesn't drop the reference anymore, do
it here unconditionally.

PM / yenta: Split resume into early and late parts (rev. 4)
Commit
0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c
(PM / yenta: Fix cardbus suspend/resume regression) caused resume to
fail on systems with two CardBus bridges. While the exact nature
of the failure is not known at the moment, it can be worked around by
splitting the yenta resume into an early part, executed during the
early phase of resume, that will only resume the socket and power it
up if there was a card in it during suspend, and a late part,
executed during "regular" resume, that will carry out all of the
remaining yenta resume operations.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a
listed regression from 2.6.31.

nilfs2: fix irregular checkpoint creation due to data flush
When nilfs flushes out dirty data to reduce memory pressure, creation
of checkpoints is wrongly postponed. This bug causes irregular
checkpoint creation especially in small footprint systems.
To correct this issue, a timer for the checkpoint creation has to be
continued if a log writer does not create a checkpoint.
This will do the correction.
