2008-07-12drivers/char/pcmcia/ipwireless/hardware.c fix resource leakDarren Jenkins
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.

2008-07-11[PATCH] IPMI: return correct value from ipmi_writeMark Rustad
This patch corrects the handling of write operations to the IPMI watchdog to work as intended by returning the number of characters actually processed. Without this patch, an "echo V >/dev/watchdog" enables the watchdog if IPMI is providing the watchdog function.

2008-07-10rtc: fix reported IRQ rate for when HPET is enabledPaul Gortmaker
The IRQ rate reported back by the RTC is incorrect when HPET is enabled. Newer hardware that has HPET to emulate the legacy RTC device gets this value wrong since after it sets the rate, it returns before setting the variable used to report the IRQ rate back to users of the device -- so the set rate and the reported rate get out of sync.

2008-07-02DRM/i915: only use tiled blits on 965+Jesse Barnes
When scheduled swaps occur, we need to blit between front & back buffers. If the buffers are tiled, we need to set the appropriate XY_SRC_COPY tile bit, but only on 965 chips, since it will cause corruption on pre-965 (e.g. 945).

2008-06-24enable bus mastering on i915 at resume timeJie Luo
On 9xx chips, bus mastering needs to be enabled at resume time for much of the chip to function. With this patch, vblank interrupts will work as expected on resume, along with other chip functions.

2008-06-20Add a bunch of cycle_kernel_lock() callsJonathan Corbet
All of the open() functions which don't need the BKL on their face may still depend on its acquisition to serialize opens against driver initialization. So make those functions acquire then release the BKL to be on the safe side. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
