this callback is called during suspend/resume and also via iw command.
it configures parameters like sifs, slottime, acktimeout in
ath9k_hw_init_global_settings where few REG_READ, REG_RMW are also done
and hence the need for PS wrappers

If is_main_vif(ar, vif) reports that we have to fall back
to software encryption, we goto err_softw; before locking ar->mutex.
As a result, we have unprotected call to carl9170_set_operating_mode
and unmatched mutex_unlock.
The patch fix the issue by adding mutex_lock before goto.

The tracing code used sched_clock() to get tracing timestamps, which
ends up calling xen_clocksource_read(). xen_clocksource_read() must
disable preemption, but if preemption tracing is enabled, this results
in infinite recursion.
I've only noticed this when boot-time tracing tests are enabled, but it
seems like a generic bug. It looks like it would also affect
kvm_clocksource_read().

The main purpose for PSW restart will be kdump. Therefore customers will
issue "system restart" for creating a dump. If kdump is not enabled,
currently "PSW restart" will reboot the system and then no dump can
be created any more. In order to still allow a manual stand-alone dump in
the case a user issues "PSW restart" on a system that has not enabled
kdump we now stop the system.

When IPL'ing from a block device and an NSS should be created we must
make sure that the kernel image and the initrd are in different 1MB
segments. Otherwise creating the NSS will fail.
So we make sure the initrd is 4MB behind the end of the kernel image
like we do already when IPL via the VM reader is performed.

Cleaning up the code a little bit. attempt_plug_merge() traverses the plug
list anyway, we can do the request counting there, so stack size is reduced
a little bit.
The motivation here is I suspect if we should count the requests for each
queue (task could handle multiple disks in the meantime), but my test doesn't
show it's worthy doing. If somebody proves we should do it, below change
will make that more easier.

Board file support for Ventana is not yet mainlined, and probably won't
ever be given the move to Device-Tree. Consequently, the Ventana entry
is being removed from arch/arm/tools/mach-types in the next merge window,
since it was registered over a year ago.
This will also remove function machine_is_ventana(), which is used by
the ASoC Tegra WM8903 machine driver. This will cause compilation
failures. Drop Ventana support to resolve this.
Hopefully, in the not-too-distant future, tegra_wm8903.c will be able to
configure itself from Device-Tree, and hence we'll be able to re-instate
Ventana support just by creating a .dts file for the board.
Also note that Aebl support is in a similar boat. However, that board
isn't scheduled for deprecation for at least another 5 months, and
perhaps we will have completely removed non-Device-Tree support from
tegra_wm8903.c by then and/or adjusted mach-types policy.

It seems that an entry for the SP805 watchdog in the table of clocks was
missing. This results in the sp805_wdt driver rejecting the device with
the following errors:
sp805-wdt mb:wdt: Clock not found
sp805-wdt mb:wdt: Probe Failed!!!
sp805-wdt: probe of mb:wdt failed with error -2
While not obviously stated in the hardware docs, the onboard SP810's
"REFCLK" is connected to a 32.768KHz crystal, and this drives the
watchdog. Add a struct clk and corresponding lookup entry for it.

Hardware allows both an outstanding number commands and a timeout value
(whichever occurs first) as a gate to the next interrupt generation. This
scheme at completion time looks at the remaining number of outstanding tasks
and sets the timeout to maximize small transaction operation. If transactions
are large (take more than a few 10s of microseconds to complete) then
performance is not interrupt processing bound, so the small timeouts this
scheme generates are overridden by the time it takes for a completion to
arrive.

Need the following workaround in the driver for interoperability with
the older Intel SSD drives and any other SATA drive that may exhibit the
same behavior. This is a corner case where SCU speed is limited to
either 3G or 1.5G and the drive has a period of DC idle when it switches
speed during SATA speed negotiation. Workaround :change PHYTOV[31:24]
from 0x36 to 0x3B.

The unsolicited frame control infrastructure requires a table of dma
addresses for the hardware to lookup the frame buffer location by an
index. The hardware expects the elements of this table to be 64-bit
quantities, so we cannot reference these elements as dma_addr_t. All
unsolicited frame protocols are affected, particularly SATA-PIO and SMP
which prevented direct-attached SATA drives and expander-attached drives
to not be discovered.

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
x86-32, vdso: On system call restart after SYSENTER, use int $0x80
x86, UV: Remove UV delay in starting slave cpus
x86, olpc: Wait for last byte of EC command to be accepted
|
|
When we enter a 32-bit system call via SYSENTER or SYSCALL, we shuffle
the arguments to match the int $0x80 calling convention. This was
probably a design mistake, but it's what it is now. This causes
errors if the system call as to be restarted.
For SYSENTER, we have to invoke the instruction from the vdso as the
return address is hardcoded. Accordingly, we can simply replace the
jump in the vdso with an int $0x80 instruction and use the slower
entry point for a post-restart.

zcache_put_page() was modified to pass page_address(page) instead of the
actual page structure. In combination with the function signature changes
to tmem_put() and zcache_pampd_create(), zcache_pampd_create() tries to
(re)derive the page structure from the virtual address. However, if the
original page is a high memory page (or any unmapped page), this
virt_to_page() fails because the page_address() in zcache_put_page()
returned NULL.
This patch changes zcache_put_page() and zcache_get_page() to pass
the page structure instead of the page's virtual address, which
may or may not exist.

wl1271_sdio_power_on checks if the return value of pm_runtime_get_sync
is non-zero, and if so bails out.
However, pm_runtime_get_sync can return a positive number which does not
suggest an error has occurred. This is problematic for two reasons:
1. The function will needlessly bail out without decrementing back the
runtime PM reference counter.
2. wl1271_power_on only checks if wl1271_power_on return value is
negative. This means that wl1271_power_on will continue even if
wl1271_sdio_power_on bailed out. As a result, sdio transactions will
be initiated without properly enabling the sdio function and claiming
the host. This could even lead to a kernel panic.
Fix this by only checking that the return value of pm_runtime_get_sync
is non-negative.

The testmode NVS push command is no longer in use. In addition, it has
several implementation issues that prevent it from working correctly:
1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However,
since the device was not necessarily booted by the time the function
is called, wl->chip.id will be initialized to 0.
2. The NVS file is fetched by calling request_firmware() before it is
possible to push an NVS file.
3. The maximum allowed size of nl binary payloads is not sufficient for
pushing NVS files.
4. Pushing 128x NVS files will always fail due to a bug in the
validation code.
5. In case the pushed NVS file is found invalid, the mutex will be kept
locked and the nvs member will become a dangling pointer.
Since this feature is not being used, remove it completely instead of
fixing it.
