This patch for the dummy_hcd driver prevents it from rejecting SET-ADDRESS requests when the address is already set. The USB 2.0 spec states that if a device is in the ADDRESS state, it should accept and start using the new address. Behavior in the CONFIGURED state is undefined, but since dummy_hcd doesn't keep track of the difference between the two states we might as well accept the new address in any case. Signed-off-by:

This is a fix for when we encounter an alias during insert. When that happens we move the request to dispatch, but it may happen that this request is also the ->last_merge hint. So we may attempt to merge with this later, when it's either in progress or already freed. Rearrange the logic a bit so we clear the merge hint there as well. It looks more complex than it is, the only real code change is the addition of a cfq_remove_merge_hints() in cfq_dispatch_sort(). Signed-off-by:Linus Torvalds <torvalds@osdl.org>

This cset adds the code to handle the hardware vector floating point unit found on some ARM926 and later CPUs. The hardware provides an implementation for the common cases, and bounces exceptions for other cases, which have to be handled in software, and signalling SIGFPE as appropriate.

Remove unused queued_signals global accounting. Signed-off-by:

Chris Wright authored
Add a user_struct pointer to the sigqueue structure. Charge sigqueue allocation and destruction to the user_struct rather than a global pool. This per user rlimit accounting obsoletes the global queued_signals accouting. The patch as charges the sigqueue struct allocation to the queue that it's pending on (the receiver of the signal). So the owner of the queue is charged for whoever writes to it (much like quota for a 777 file). The patch started out charging the task which allocated the sigqueue struct. In most cases, these are always the same user (permission for sending a signal), so those cases are moot. In the cases where it isn't the same user, it's a privileged user sending a signal to another user. It seems wrong to charge the allocation to the privleged user, when the other user could block receipt as long as it feels. The flipside is, someone else can fill your queue (expectation is that someone else is privileged). I think it's right the way it is. The change to revert is very small. Signed-off-by:

Distros have started to ship kernels with this patch, as it seems that some unnamed binary module authors are already abusing this function (as well as some open source modules, like the openib code.) I could not find any valid reason why this symbol should be exported, so here's a patch against 2.6.7 that removes it. Signed-off-by:

Hit a bug check when unmap a hugetlb vma in PAE mode on i386 (and x86-64). Bad page state at free_hot_cold_page (in process 'a.out', page c165cc40) flags:0x20000000 mapping:f75e1d00 mapped:0 count:0 Backtrace: Call Trace: [<c0133e0d>] bad_page+0x79/0x9e [<c0134550>] free_hot_cold_page+0x71/0xfa [<c0115d60>] unmap_hugepage_range+0xa3/0xbf [<c013d375>] unmap_vmas+0xac/0x252 [<c0117691>] default_wake_function+0x0/0xc [<c0140bea>] unmap_region+0xd8/0x145 [<c0140f2d>] do_munmap+0xfc/0x14d [<c01b8a56>] sys_shmdt+0xa5/0x126 [<c010a2ad>] sys_ipc+0x23c/0x27f [<c014a85e>] sys_write+0x38/0x59 [<c0103e1b>] syscall_call+0x7/0xb It turns out there is a bug in hugetlb_prefault(): with 3 level page table, huge_pte_alloc() might return a pmd that points to a PTE page. It happens if the virtual address for hugetlb mmap is recycled from previously used normal page mmap. free_pgtables() might not scrub the pmd entry on munmap and hugetlb_prefault skips on any pmd presence regardless what type it is.

This patch fixes some problems with handling of channel detection in the driver. Some systems that are IPMI 1.5 do not implement the channel query command. Also, the interface has to be fully up before the command is ready. This patch also adds a polling interface; this is required for situations where interrupts are not running, but the system must still issue IPMI commands, like when taking a crash dump. It also updates the driver version to v32. Signed-off-by:

This patch regenerates the SELinux module headers to reflect new class and access vectors definitions. The size of the diff is misleading; much of it is simply a change in the ordering of the automatically generated definitions. The corresponding generation script has been changed to ensure a stable order in the future. Please apply. Author: Stephen Smalley <sds@epoch.ncsc.mil> Cc: David S.

asiliantfb seems to have only been partially merged (the fbmem.c bits in particular seem to have been missed entirely). This adds them back in, though they do seem to be present in the fbdev tree, at least they were the last time I looked. These are the last bit of outstanding changes I have in the LinuxSH tree for asiliantfb, so it would be nice to get this out of the way. Signed-off-by:

1. pass info->monspecs.modedb and info->monspecs.modedb_len to fb_find_mode() instead of NULL, 0 since its contents are specific to the attached display. Anyway, if info->monspecs.modedb == NULL, fb_find_mode() will use the default database. 2. Added best fit algo to fb_find_mode(). 3. Use snprintf instead of sprintf. Signed-off-by:

The patch updates rivafb to the following: 1. Fixed cursor corruption and simplified cursor code. 2. Maximized var->yres_virtual on initial mode setting. Scrolling, therefore, defaults to y-panning which is significantly faster. 3. Restricted var->xres_virtual and var->yres_virtual to 0x7fff (hardware limitation?). Otherwise, var->yres_virtual > 0x7fff + panning will hang the GPU. 4. Added I2C/DDC support. This feature enables independent mode setup to rivafb. 'stty rows n cols n' should now work correctly. This is a configurable option. 5. Various/minor fixes to drawing code. Signed-off-by:

Baseline patch to make framebuffer/fbcon interaction more sane by basing the fbcon heuristics on capabilities advertized by underlying framebuffer via the fb_info.flags field. This patch updates fbcon, fb.h, and skeletonfb.c. It does *not* yet update the drivers themselves. They should compile and work, but their hinting is not correct yet, meaning most fb drivers will be slow until I set the flags to the right hinting driver-by-driver Signed-off-by:

The fsx-linux hole fill failure problem was caused by generic_file_aio_write_nolock() not handling the partial DIO write correctly. Here's a patch lets DIO do the partial write, and the fallback to buffered is done (correctly) for what is left. This fixes the hole filling without retrying the entire i/o. This patch also applies to 2.6.7-rc3 with some offset. I tested this (on ext3) with fsx-linux -l 500000 -r 4096 -t 4096 -w 4096 -Z -N 10000 junk -R -W Signed-off-by:

The SetPageUptodate function is called for pages that are already up to date. The arch_set_page_uptodate function of s390 may not clear the dirty bit in that case otherwise a dirty bit which is set between the start of an i/o for a writeback and a following call to SetPageUptodate is lost.
