2010-04-07mb862xxfb: fix acceleration module licenseRandy Dunlap
mb862xxfb_accel built as a separate module, but it does not have a MODULE_LICENSE, so it taints the kernel. Add a MODULE_LICENSE to it (same as mb862xxfb license). mb862xxfb_accel: module license 'unspecified' taints kernel. Or should mb862xxfb_accel be built into the mb862xxfb binary file instead?

2010-04-07mm: revert "vmscan: get_scan_ratio() cleanup"KOSAKI Motohiro
Shaohua Li reported his tmpfs streaming I/O test can lead to make oom. The test uses a 6G tmpfs in a system with 3G memory. In the tmpfs, there are 6 copies of kernel source and the test does kbuild for each copy. His investigation shows the test has a lot of rotated anon pages and quite few file pages, so get_scan_ratio calculates percent[0] (i.e. scanning percent for anon) to be zero. Actually the percent[0] shoule be a big value, but our calculation round it to zero. Although before commit 84b18490 ("vmscan: get_scan_ratio() cleanup") , we have the same problem too. But the old logic can rescue percent[0]==0 case only when priority==0. It had hided the real issue. I didn't think merely streaming io can makes percent[0]==0 && priority==0 situation. but I was wrong. So, definitely we have to fix such tmpfs streaming io issue. but anyway I revert the regression commit at first. This reverts commit 84b18490d1f1bc7ed5095c929f78bc002eb70f26.

2010-04-07devmem: handle class_create() failureAnton Blanchard
I hit this when we had a bug in IDR for a few days. Basically sysfs would fail to create new inodes since it uses an IDR and therefore class_create would fail. While we are unlikely to see this fail we may as well handle it instead of oopsing.

2010-04-07device_attributes: add sysfs_attr_init() for dynamic attributesWolfram Sang
Made necessary by 6992f5334995af474c2b58d010d08bc597f0f2fe ("sysfs: Use one lockdep class per sysfs attribute"). Prevents further "key xxx not in .data" bug-reports. Although some attributes could probably be converted to static ones, this is left for people having hardware to test.

Commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers: move probe to .devinit.text in drivers/video") introduced a huge amount of section mismatch warnings in vesafb code. Rather than converting all of the annotations, do the obvious and revert the __init -> __devinit change, and use the recommended (in that patch) alternative to calling platform_driver_register(): vesafb depends on information obtained from by kernel at boot time, cannot be a module, and no post-boot devices can ever show up.

2010-04-07x86/amd-iommu: enable iommu before attaching devicesChris Wright
Hit another kdump problem as reported by Neil Horman. When initializaing the IOMMU, we attach devices to their domains before the IOMMU is fully (re)initialized. Attaching a device will issue some important invalidations. In the context of the newly kexec'd kdump kernel, the IOMMU may have stale cached data from the original kernel. Because we do the attach too early, the invalidation commands are placed in the new command buffer before the IOMMU is updated w/ that buffer. This leaves the stale entries in the kdump context and can renders device unusable. Simply enable the IOMMU before we do the attach.

When ide taskfile access is being used (for example with hdparm --security commands) and cfq scheduler is selected, the scheduler crashes on BUG in cfq_put_request. The reason is that the cfq scheduler is tracking counts of read and write requests separately; the ide-taskfile subsystem allocates a read request and then flips the flag to make it a write request. The counters in cfq will mismatch. This patch changes ide-taskfile to allocate the READ or WRITE request as required and don't change the flag later.
