OMAP2 SDRC: add SDRAM timing parameter infrastructure
For a given SDRAM clock rate, SDRAM chips require memory controllers
to use a specific set of timing minimums and maximums to transfer data
reliably. These parameters can be different for different memory chips
and can also potentially vary by board.
This patch adds the infrastructure for board-*.c files to pass this
timing data to the SDRAM controller init function. The timing data is
specified in an 'omap_sdrc_params' structure, in terms of SDRC
controller register values. An array of these structs, one per SDRC
target clock rate, is passed by the board-*.c file to
omap2_init_common_hw().
This patch does not define the values for different memory chips, nor
does it use the values for anything; those will come in subsequent patches.

TWL4030: use *_SIH_CTRL.COR bit to determine whether to read or write ISR to clear
TWL4030 interrupt status register bits can be cleared in one of two ways:
either by reading from the register, or by writing a 1 to the
appropriate bit(s) in the register. This behavior can be altered at any
time by the <twlmodule>_SIH_CTRL.COR register bit ("clear-on-read").
The TWL4030 TRM is deeply confused as to whether COR=1 means that the
registers are cleared on reads, or cleared on writes. Peter De
Schrijver <peter.de-schrijver> confirms that COR=1 means that the registers
are cleared on read.
So, for each TWL4030 SIH, check the value of the *_SIH_CTRL.COR bit, and if
it is 1, use reads to clear the ISRs; if it is 0, use writes.
Also, use WARN_ON() to warn if the read/write failed, and don't skip
the rest of the initialization on failure either.

i2c-omap: close suspected race between omap_i2c_idle() and omap_i2c_isr()
omap_i2c_idle() sets an internal flag, "dev->idle", instructing its
ISR to decline interrupts. It sets this flag before it actually masks
the interrupts on the I2C controller. This is problematic, since an
I2C interrupt could arrive after dev->idle is set, but before the
interrupt source is masked. When this happens, Linux disables the I2C
controller's IRQ, causing all future transactions on the bus to fail.
Symptoms, happening on about 7% of boots:
irq 56: nobody cared (try booting with the "irqpoll" option)

In omap_i2c_idle(), this patch sets dev->idle only after the interrupt
mask write to the I2C controller has left the ARM write buffer.
That's probably the major offender. For additional prophylaxis, in
omap_i2c_unidle(), the patch clears the dev->idle flag before
interrupts are enabled, rather than afterwards.

cpusets, hotplug, scheduler: fix scheduler domain breakage
Commit
f18f982ab ("sched: CPU hotplug events must not destroy scheduler
domains created by the cpusets") introduced a hotplug-related problem as
described below:
Upon CPU_DOWN_PREPARE,
update_sched_domains() -> detach_destroy_domains(&cpu_online_map)
does the following:
/*
* Force a reinitialization of the sched domains hierarchy. The domains
* and groups cannot be updated in place without racing with the balancing
* code, so we temporarily attach all running cpus to the NULL domain
* which will prevent rebalancing while the sched domains are recalculated.
*/
The sched-domains should be rebuilt when a CPU_DOWN ops. has been
completed, effectively either upon CPU_DEAD{_FROZEN} (upon success) or
CPU_DOWN_FAILED{_FROZEN} (upon failure -- restore the things to their
initial state). That's what update_sched_domains() also does but only
for !CPUSETS case.
With
f18f982ab, sched-domains' reinitialization is delegated to
CPUSETS code:
cpuset_handle_cpuhp() -> common_cpu_mem_hotplug_unplug() ->
rebuild_sched_domains()
Being called for CPU_UP_PREPARE and if its callback is called after
update_sched_domains()), it just negates all the work done by
update_sched_domains() -- i.e. a soon-to-be-offline cpu is included in
the sched-domains and that makes it visible for the load-balancer
while the CPU_DOWN ops. is in progress.
__migrate_live_tasks() moves the tasks off a 'dead' cpu (it's already
"offline" when this function is called).
try_to_wake_up() is called for one of these tasks from another CPU ->
the load-balancer (wake_idle()) picks up a "dead" CPU and places the
task on it. Then e.g. BUG_ON(rq->nr_running) detects this a bit later
-> oops.

This patch is a bugfix for how defio handles multiple processes manipulating

Thanks to Bernard Blackham for identifying this bug.
It occurs when two applications mmap the same framebuffer and concurrently
write to the same page. Normally, this doesn't occur since only a single
process mmaps the framebuffer. The symptom of the bug is that the mapping
applications will hang. The cause is that defio incorrectly tries to add the
same page twice to the pagelist. The solution I have is to walk the pagelist
and check for a duplicate before adding. Since I needed to walk the pagelist,
I now also keep the pagelist in sorted order.

drivers/char/pcmcia/ipwireless/hardware.c fix resource leak
Coverity CID: 2172 RESOURCE_LEAK
When pool_allocate() tries to enlarge a packet, if it can not allocate enough
memory, it returns NULL without first freeing the old packet.
This patch just frees the packet first.

[SCSI] bsg: fix oops on remove
If you do a modremove of any sas driver, you run into an oops on
shutdown when the host is removed (coming from the host bsg device).
The root cause seems to be that there's a use after free of the
bsg_class_device: In bsg_kref_release_function, this is used (to do a
put_device(bcg->parent) after bcg->release has been called. In sas (and
possibly many other things) bcd->release frees the queue which contains
the bsg_class_device, so we get a put_device on unreferenced memory.
Fix this by taking a copy of the pointer to the parent before releasing
bsg.

[SCSI] fusion: default MSI to disabled for SPI and FC controllers
There's a fault on the FC controllers that makes them not respond
correctly to MSI. The SPI controllers are fine, but are likely to be
onboard on older motherboards which don't handle MSI correctly, so
default both these cases to disabled. Enable by setting the module
parameter mpt_msi_enable=1.
For the SAS case, enable MSI by default, but it can be disabled by
setting the module parameter mpt_msi_enable=0.

This patch corrects the handling of write operations to the IPMI watchdog

[SCSI] ipr: Fix HDIO_GET_IDENTITY oops for SATA devices
Currently, ipr does not support HDIO_GET_IDENTITY to SATA devices.
An oops occurs if userspace attempts to send the command. Since hald
issues the command, ensure we fail the ioctl in ipr. This is a
temporary solution to the oops. Once the ipr libata EH conversion
is upstream, ipr will fully support HDIO_GET_IDENTITY.

Fix reference counting race on log buffers
When we release the iclog, we do an atomic_dec_and_lock to determine if
we are the last reference and need to trigger update of log headers and
writeout. However, in xlog_state_get_iclog_space() we also need to
check if we have the last reference count there. If we do, we release
the log buffer, otherwise we decrement the reference count.
But the compare and decrement in xlog_state_get_iclog_space() is not
atomic, so both places can see a reference count of 2 and neither will
release the iclog. That leads to a filesystem hang.
Close the race by replacing the atomic_read() and atomic_dec() pair with
atomic_add_unless() to ensure that they are executed atomically.

libata-acpi: filter out DIPM enable
Some BIOSen enable DIPM via _GTF which causes command timeouts under
certain configuration. This didn't occur on 2.6.25 because 2.6.25
defaulted to SRST, so _GTF wasn't executed during boot probe, so ahci
host reset disabled DIPM and as _GTF wasn't executed after SRST, DIPM
wasn't enabled. On 2.6.26, hardreset is used during probe and after
probe _GTF is executed enabling DIPM and thus the failures.
This patch could theoretically disable DIPM on machines which used to
have it enabled on 2.6.25 but AFAIK ahci is currently the only driver
which uses SATA ACPI hierarchy (_SDD) and as the host reset would have
always disabled DIPM, this shouldn't happen.
