With the code cleanup in 7a6b2896f261894dde287d3faefa4b432cddca53 is the first bad commit commit 7a6b2896f261894dde287d3faefa4b432cddca53 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 2 15:02:15 2010 +0100 drm_mm: extract check_free_mm_node I've botched up the range-restriction checks. The result is usually an X server dying with SIGBUS in libpixman (software fallback rendering). Change the code to adjust the start and end for range restricted allocations.

2010-08-26amd64_edac: Do not report error overflow as a separate errorBorislav Petkov
When the Overflow MCi_STATUS bit is set, EDAC reports the lost error with a "no information available" message which often puzzles users parsing the dmesg. This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous. Now it looks like this: [ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error [ 1501.666887] Northbridge Error, node 2 Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>

Fix DSM/TRIM commands in sata_mv (v2). These need to be issued using old-school "BM DMA", rather than via the EDMA host queue. Since the chips don't have proper BM DMA status, we need to be more careful with setting the ATA_DMA_INTR bit, since DSM/TRIM often has a long delay between "DMA complete" and "command complete". GEN_I chips don't have BM DMA, so no TRIM for them. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Cc: stable@kernel.org

2010-08-25hwmon: (k8temp) Differentiate between AM2 and ASB1Andreas Herrmann
Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix temperature reporting for ASB1 processor revisions) fixed temperature reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f) were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit leads to wrong temperature reporting for AM2 CPU parts. The solution is to determine the package type for models 0x6b, 0x6f, 0x7f. This is done using BrandId from CPUID Fn8000_0001_EBX[15:0].

2010-08-24xen: handle events as edge-triggeredJeremy Fitzhardinge
Xen events are logically edge triggered, as Xen only calls the event upcall when an event is newly set, but not continuously as it remains set. As a result, use handle_edge_irq rather than handle_level_irq. This has the important side-effect of fixing a long-standing bug of events getting lost if: - an event's interrupt handler is running - the event is migrated to a different vcpu - the event is re-triggered The most noticable symptom of these lost events is occasional lockups of blkfront. Many thanks to Tom Kopec and Daniel Stodden in tracking this down.

2010-08-24xen: use percpu interrupts for IPIs and VIRQsJeremy Fitzhardinge
IPIs and VIRQs are inherently per-cpu event types, so treat them as such: - use a specific percpu irq_chip implementation, and - handle them with handle_percpu_irq This makes the path for delivering these interrupts more efficient (no masking/unmasking, no locks), and it avoid problems with attempts to migrate them.

This patch fixes a isoc transfer bug reported by Sander Eikelenboom. When ep->skip is set, endpoint ring dequeue pointer should be updated when processed every missed td. Although ring dequeue pointer will also be updated when ep->skip is clear, leave it intact during missed tds processing may cause two issues: 1). If the very next valid transfer following missed tds is a short transfer, its actual_length will be miscalculated; 2). If there are too many missed tds during transfer, new inserted tds may found the transfer ring full and urb enqueue fails.

The code to increment the TRB pointer has a slight ambiguity that could lead to a bug on different compilers. The ANSI C specification does not specify the precedence of the assignment operator over the postfix operator. gcc 4.4 produced the correct code (increment the pointer and assign the value), but a MIPS compiler that one of John's clients used assigned the old (unincremented) value.
