This bug causes the IECSR register clear failure. In this case, the RETE
(retry error threshold exceeded) interrupt will be generated and cannot be
cleared. So the related ISR may be called persistently.
The RETE bit in IECSR is cleared by writing a 1 to it.

have irq.
The previous rtc-s3c had two issues related with its IRQ.
1. Users cannot open rtc multiple times because an open operation
calls request_irq on the same IRQ. (e.g., two user processes wants to
open and read RTC time from rtc-s3c at the same time)
2. If alarm is set and no one has the rtc opened with filesystem
(either the alarm is set by kernel/boot-loader or user set an alarm and
closed rtc dev file), the pending bit is not cleared and no further
interrupt is invoked. When the alarm is used by the system itself such
as a resume from suspend-to-RAM or other Low-power modes/idle, this is
a critical issue.
This patch mitigates these issues by calling request_irq at probe and
free_irq at remove.

Commit 79dfdaccd1d5 ("memcg: make oom_lock 0 and 1 based rather than
counter") tried to oom lock the hierarchy and roll back upon
encountering an already locked memcg.
The code is confused when it comes to detecting a locked memcg, though,
so it would fail and rollback after locking one memcg and encountering
an unlocked second one.
The result is that oom-locking hierarchies fails unconditionally and
that every oom killer invocation simply goes to sleep on the oom
waitqueue forever. The tasks practically hang forever without anyone
intervening, possibly holding locks that trip up unrelated tasks, too.

Replace/remove use of RIO v.1.2 registers/bits that are not
forward-compatible with newer versions of RapidIO specification.
RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR,
Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR.
Use of removed (since RIO v.1.3) register bits affects users of
currently available 1.3 and 2.x compliant devices who may use not so
recent kernel versions.
Removing checks for unsupported bits makes corresponding routines
compatible with all versions of RapidIO specification. Therefore,
backporting makes stable kernel versions compliant with RIO v.1.3 and
later as well.

ZONE_CONGESTED is only cleared in kswapd, but pages can be freed in any
task. It's possible ZONE_CONGESTED isn't cleared in some cases:
1. the zone is already balanced just entering balance_pgdat() for
order-0 because concurrent tasks free memory. In this case, later
check will skip the zone as it's balanced so the flag isn't cleared.
2. high order balance fallbacks to order-0. quote from Mel: At the
end of balance_pgdat(), kswapd uses the following logic;
If reclaiming at high order {
for each zone {
if all_unreclaimable
skip
if watermark is not met
order = 0
loop again
/* watermark is met */
clear congested
}
}
i.e. it clears ZONE_CONGESTED if it the zone is balanced. if not,
it restarts balancing at order-0. However, if the higher zones are
balanced for order-0, kswapd will miss clearing ZONE_CONGESTED as
that only happens after a zone is shrunk. This can mean that
wait_iff_congested() stalls unnecessarily.
This patch makes kswapd clear ZONE_CONGESTED during its initial
highmem->dma scan for zones that are already balanced.

It seems that 7bf693951a8e ("console: allow to retain boot console via
boot option keep_bootcon") doesn't always achieve what it aims, as when
printk_late_init() runs it unconditionally turns off all boot consoles.
With this patch, I am able to see more messages on the boot console in
KVM guests than I can without, when keep_bootcon is specified.
I think it is appropriate for the relevant -stable trees. However, it's
more of an annoyance than a serious bug (ideally you don't need to keep
the boot console around as console handover should be working -- I was
encountering a situation where the console handover wasn't working and
not having the boot console available meant I couldn't see why).

Commit d1a05b6973c7 ("memcg do not try to drain per-cpu caches without
pages") added a drain_local_stock() call to a preemptible section.
The draining task looks up the cpu-local stock twice to set the
draining-flag, then to drain the stock and clear the flag again. If the
task is migrated to a different CPU in between, noone will clear the
flag on the first stock and it will be forever undrainable. Its charge
can not be recovered and the cgroup can not be deleted anymore.
Properly pin the task to the executing CPU while draining stocks.

The bug was accidentally found by the following program:
#include <asm/sysinfo.h>
#include <asm/unistd.h>
#include <sys/syscall.h>
static int setsysinfo(unsigned long op, void *buffer, unsigned long size,
int *start, void *arg, unsigned long flag) {
return syscall(__NR_osf_setsysinfo, op, buffer, size, start, arg, flag);
}
int main(int argc, char **argv) {
short x[10];
unsigned int buf[2] = { SSIN_UACPROC, UAC_SIGBUS, };
setsysinfo(SSI_NVPAIRS, buf, 1, 0, 0, 0);
int *y = (int*) (x+1);
*y = 0;
return 0;
}
The program shoud fail on SIGBUS, but didn't.
The patch is a second part of userspace flag fix (commit 745dd2405e28
"Alpha: Rearrange thread info flags fixing two regressions").
Deleted outdated out-of-sync 'UAC_SHIFT' (the cause of bug) in favour of

Purely in-memory filesystems do not use the inode hash as the dcache
tells us if an entry already exists. As a result, they do not call
unlock_new_inode, and thus directory inodes do not get put into a
different lockdep class for i_sem.
We need the different lockdep classes, because the locking order for
i_mutex is different for directory inodes and regular inodes. Directory
inodes can do "readdir()", which takes i_mutex *before* possibly taking
mm->mmap_sem (due to a page fault while copying the directory entry to
user space).
In contrast, regular inodes can be mmap'ed, which takes mm->mmap_sem
before accessing i_mutex.
The two cases can never happen for the same inode, so no real deadlock
can occur, but without the different lockdep classes, lockdep cannot
understand that. As a result, if CONFIG_DEBUG_LOCK_ALLOC is set, this
can lead to false positives from lockdep like below:
find/645 is trying to acquire lock:
(&mm->mmap_sem){++++++}, at: [<ffffffff81109514>] might_fault+0x5c/0xac
but task is already holding lock:
(&sb->s_type->i_mutex_key#15){+.+.+.}, at: [<ffffffff81149f34>]
vfs_readdir+0x5b/0xb4
which lock already depends on the new lock.
the existing dependency chain (in reverse order) is:

I ran into a couple of programs which broke with the new Linux 3.0
version. Some of those were binary only. I tried to use LD_PRELOAD to
work around it, but it was quite difficult and in one case impossible
because of a mix of 32bit and 64bit executables.
For example, all kind of management software from HP doesnt work, unless
we pretend to run a 2.6 kernel.
$ uname -a
Linux svivoipvnx001 3.0.0-08107-g97cd98f #1062 SMP Fri Aug 12 18:11:45 CEST 2011 i686 i686 i386 GNU/Linux
$ hpacucli ctrl all show
Error: No controllers detected.
$ rpm -qf /usr/sbin/hpacucli
hpacucli-8.75-12.0
Another notable case is that Python now reports "linux3" from
sys.platform(); which in turn can break things that were checking
sys.platform() == "linux2":
https://bugzilla.mozilla.org/show_bug.cgi?id=664564
It seems pretty clear to me though it's a bug in the apps that are using
'==' instead of .startswith(), but this allows us to unbreak broken
programs.
This patch adds a UNAME26 personality that makes the kernel report a
2.6.40+x version number instead. The x is the x in 3.x.
I know this is somewhat ugly, but I didn't find a better workaround, and
compatibility to existing programs is important.
Some programs also read /proc/sys/kernel/osrelease. This can be worked
around in user space with mount --bind (and a mount namespace)
To use:

Calao use on there dev kits a FT2232 where the port 0 is used for the JTAG and
port 1 for the UART
They use the same VID and PID as FTDI Chip but they program the manufacturer
name in the eeprom
So use this information to detect it

Upstream commit d5341942d784134f2997b3ff82cd63cf71d1f932 "PCI: Make the

Commit c03f007a8bf0e092caeb6856a5c8a850df10b974 (OMAP: PM:
omap_device: add system PM methods for PM domain handling) mistakenly
used SET_SYSTEM_SLEEP_PM_OPS() when trying to configure custom methods
for the PM domains noirq methods. Fix that by setting only the
suspend_noirq and resume_noirq methods with custom versions.
Note that all other PM domain methods (including the "normal"
suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS,
which configures them all to the default subsystem (platform_bus)
methods.

Headphones has stopped working for the original reported (a regression
compared to 2.6.38). This is because Speaker and Headphones share the
same DAC, in which case no Headphones volume control was created.
This patch fixes so that both Speaker and Headphones volume
controls are created in such scenario.

This is basically a more generic respin of 23746a6 ("HID: magicmouse: ignore
'ivalid report id' while switching modes") which got reverted later by
c3a492.
It turns out that on some configurations, this is actually still the case
and we are not able to detect in runtime.
The device reponds with 'invalid report id' when feature report switching it
into multitouch mode is sent to it.
This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK
on Sent Reports"), but since this commit, it propagates -EIO from the _raw
callback .
So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's
how the device reacts in normal mode.
Sad, but following reality.
