2011-09-12block: remove support for bio remapping from ->make_requestChristoph Hellwig
There is very little benefit in allowing to let a ->make_request instance update the bios device and sector and loop around it in __generic_make_request when we can archive the same through calling generic_make_request from the driver and letting the loop in generic_make_request handle it. Note that various drivers got the return value from ->make_request and returned non-zero values for errors.

2011-08-07sh: Fix boot crash related to SCIRafael J. Wysocki
Commit d006199e72a9 ("serial: sh-sci: Regtype probing doesn't need to be fatal.") made sci_init_single() return when sci_probe_regmap() succeeds, although it should return when sci_probe_regmap() fails. This causes systems using the serial sh-sci driver to crash during boot. Fix the problem by using the right return condition. Signed-off-by: Rafael J.

2011-08-06net: Compute protocol sequence numbers and fragment IDs using MD5.David S. Miller
Computers have become a lot faster since we compromised on the partial MD4 hash which we use currently for performance reasons. MD5 is a much safer choice, and is inline with both RFC1948 and other ISS generators (OpenBSD, Solaris, etc.) Furthermore, only having 24-bits of the sequence number be truly unpredictable is a very serious limitation. So the periodic regeneration and 8-bit counter have been removed. We compute and use a full 32-bit sequence number. For ipv6, DCCP was found to use a 32-bit truncated initial sequence number (it needs 43-bits) and that is fixed here as well.

2011-08-06savagedb: Fix typo causing regression in savage4 series video chip detectionJohn Stanley
Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES macro was incompletely modified, resulting in a false positive detection of a savage4 card regardless of which savage card is actually present. For non-savage4 series cards, such as a Savage/IX-MV card, this results in garbled video and/or a hard-hang at boot time. Fix this by changing an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.

2011-08-05PM / Runtime: Allow _put_sync() from interrupts-disabled contextKevin Hilman
Currently the use of pm_runtime_put_sync() is not safe from interrupts-disabled context because rpm_idle() will release the spinlock and enable interrupts for the idle callbacks. This enables interrupts during a time where interrupts were expected to be disabled, and can have strange side effects on drivers that expected interrupts to be disabled. This is not a bug since the documentation clearly states that only _put_sync_suspend() is safe in IRQ-safe mode. However, pm_runtime_put_sync() could be made safe when in IRQ-safe mode by releasing the spinlock but not re-enabling interrupts, which is what this patch aims to do. Problem was found when using some buggy drivers that set pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled context.
