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). Bug reported by and fix tested by Tomas Janousek <tomi@nomi.cz>.

2008-06-19agp: two-stage page destruction issueJan Beulich
besides it apparently being useful only in 2.6.24 (the changes in 2.6.25 really mean that it could be converted back to a single-stage mechanism), I'm seeing an issue in Xen Dom0 kernels, which is caused by the calling of gart_to_virt() in the second stage invocations of the destroy function. I think that besides this being a real issue with Xen (where unmap_page_from_agp() is not just a page table attribute change), this also is invalid from a theoretical perspective: One should not assume that gart_to_virt() is still valid after unmapping a page. So minimally (keeping the 2-stage mechanism) a patch like the one below would be needed. Jan Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-06-12rtc: make HPET_RTC_IRQ track HPET_EMULATE_RTCDavid Brownell
More Kconfig tweaks related to the legacy PC RTC code: - Describe the legacy PC RTC driver as such ... it's never quite been clear that this driver is for PC RTCs, and now it's fair to call this the "legacy" driver. - Force it to understand about HPET stealing its IRQs ... kernel code does this always when HPET is in use, there should be no option for users to goof up the config. This seems to fix kernel bugzilla #10729.
