[PATCH] blk: fix tag shrinking (revive real_max_size)
My patch in commit
fa72b903f75e4f0f0b2c2feed093005167da4023 incorrectly
removed blk_queue_tag->real_max_depth.
The original resize implementation was incorrect in the following
points.
* actual allocation size of tag_index was shorter than real_max_size,
but assumed to be of the same size, possibly causing memory access
beyond the allocated area.
* bits in tag_map between max_deptn and real_max_depth were
initialized to 1's, making the tags permanently reserved.
In an attempt to fix above two bugs, I had removed allocation optimization
in init_tag_map and real_max_size. Tag map/index were allocated and freed
immediately during resize.
Unfortunately, I wasn't considering that tag map/index can be resized
dynamically with tags beyond new_depth active. This led to accessing
freed area after shrinking tags and led to the following bug reporting
thread on linux-scsi.
http://marc.theaimsgroup.com/?l=linux-scsi&m=
112319898111885&w=2
To fix the problem, I've revived real_max_depth without allocation
optimization in init_tag_map, and Andrew Vasquez confirmed that the
problem was fixed. As Jens is not going to be available for a week, he
asked me to make sure that this patch reaches you.

[PATCH] rtc: msleep() cannot be used from interrupt
Since the beginning of July my Opteron box was randomly crashing and
being rebooted by hardware watchdog. Today it finally did it in front
of me, and this patch will hopefully fix it.
The problem is that at the end of June (the 28th, to be exact: commit
47f176fdaf8924bc83fddcf9658f2fd3ef60d573, "[PATCH] Using msleep()
instead of HZ") rtc_get_rtc_time was converted to use msleep() instead
of busy waiting. But rtc_get_rtc_time is used by hpet_rtc_interrupt,
and scheduling is not allowed during interrupt. So I'm reverting this
part of original change, replacing msleep() back with busy loop.
The original code was busy waiting for up to 20ms, but on my hardware in
the worst case update-in-progress bit was asserted for at most 363
passes through loop (on 2GHz dual Opteron), much less than even one
jiffie, not even talking about 20ms. So I changed code to just wait
only as long as necessary. Otherwise when RTC was set to generate
8192Hz timer, it stopped doing anything for 20ms (160 pulses were
skipped!) from time to time, and this is rather suboptimal as far as I
can tell.

We have found what seems to be a small bug in __vm_enough_memory() when

When this bug occurs the systems fails to boot, with /sbin/init whining
about fork() returning ENOMEM.
We hunted down the problem to this:
The deferred update mecanism used in vm_acct_memory(), on a SMP system,
allows the vm_committed_space counter to have a negative value.
This should not be a problem since this counter is known to be inaccurate.
But in __vm_enough_memory() this counter is compared to the `allowed'
variable, which is an unsigned long. This comparison is broken since it
will consider the negative values of vm_committed_space to be huge positive
values, resulting in a memory allocation failure.

[PATCH] PCI: restore BAR values after D3hot->D0 for devices that need it
Some PCI devices (e.g. 3c905B, 3c556B) lose all configuration
(including BARs) when transitioning from D3hot->D0. This leaves such
a device in an inaccessible state. The patch below causes the BARs
to be restored when enabling such a device, so that its driver will
be able to access it.
The patch also adds pci_restore_bars as a new global symbol, and adds a
correpsonding EXPORT_SYMBOL_GPL for that.
Some firmware (e.g. Thinkpad T21) leaves devices in D3hot after a
(re)boot. Most drivers call pci_enable_device very early, so devices
left in D3hot that lose configuration during the D3hot->D0 transition
will be inaccessible to their drivers.
Drivers could be modified to account for this, but it would
be difficult to know which drivers need modification. This is
especially true since often many devices are covered by the same
driver. It likely would be necessary to replicate code across dozens
of drivers.
The patch below should trigger only when transitioning from D3hot->D0
(or at boot), and only for devices that have the "no soft reset" bit
cleared in the PM control register. I believe it is safe to include
this patch as part of the PCI infrastructure.
The cleanest implementation of pci_restore_bars was to call
pci_update_resource. Unfortunately, that does not currently exist
for the sparc64 architecture. The patch below includes a null
implemenation of pci_update_resource for sparc64.
Some have expressed interest in making general use of the the
pci_restore_bars function, so that has been exported to GPL licensed
modules.

(2) request_key() returns ENOKEY rather than EPERM if the key type begins

lookup_user_key() can't do this because internal key types begin with a

(3) Key revocation always returns 0, even if it fails.
(4) Key read can return EAGAIN rather than EACCES under some circumstances.
A key is permitted to by read by a process if it doesn't grant read
access, but it does grant search access and it is in the process's
keyrings. That search returns EAGAIN if it fails, and this needs
translating to EACCES.
(5) request_key() never adds the new key to the destination keyring if one is

shutdown and the suspend() code isn't yet in a good enough shape to be

You also asked me to involve the watchdog maintainer which I tried to
do but didn't hear anything back. There are only a couple of other
drivers which can't stop the watchdog and there seems to be no
consistancy regarding printing an error etc. I decided to print
something since that matches the case for all the other drivers when
NOWAYOUT is turned on.
Also, I changed the device .name to "watchdog" like most of the other
watchdogs. udev uses it as the device name (by default) and spaces etc.

[PATCH] ppc64: POWER 4 fails to boot with NUMA
If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is
because of special processing needed to handle invalid node IDs (0xffff) on
POWER 4. My previous patch to handle memory 'holes' within nodes forgot to
add this special case for POWER 4 in one place.
In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes
much sense. Are there POWER 4 based systems with NUMA characteristics that
are presented by the firmware? But, distros want one kernel for all systems
so NUMA is on by default in their kernels. The patch handles those cases.

[PATCH] Module per-cpu alignment cannot always be met
The module code assumes noone will ever ask for a per-cpu area more than
SMP_CACHE_BYTES aligned. However, as these cases show, gcc asks sometimes
asks for 32-byte alignment for the per-cpu section on a module, and if
CONFIG_X86_L1_CACHE_SHIFT is 4, we hit that BUG_ON(). This is obviously an
unusual combination, as there have been few reports, but better to warn
than die.

[PATCH] sys_set_mempolicy() doesnt check if mode < 0
A kernel BUG() is triggered by a call to set_mempolicy() with a negative
first argument. This is because the mode is declared as an int, and the
validity check doesnt check < 0 values. Alternatively, mode could be
declared as unsigned int or unsigned long.

[PATCH] m32r: Fix local-timer event handling
There was a scheduling problem of the m32r SMP kernel; A process rarely
stopped and gave no responding but the other process have been handled by
the other CPU still lives, then if we did something in the other terminal
or something like that, the stopped process came back to life and continued
its operation... (ex. LMbench: lat_sig)
In the m32r SMP kernel, a local-timer event is delivered by using an
IPI(inter processor interrupts); LOCAL_TIMER_IPI. And a function
smp_send_timer() is prepared to send the LOCAL_TIMER_IPI from the current
CPU to the other CPUs.
The funtion smp_send_timer() was placed and used in do_IRQ() in
former times (before 2.6.10-rc3-mm1 kernel), however, it was
unintentionally removed when arch/m32r/kernel/irq.c was modified to
employ the generic hardirq framework (CONFIG_GENERIC_HARDIRQ) in
my previous patch.
