This is what a lot of drivers will actually want to use to insert individual pages into a user VMA. It doesn't have the old PageReserved restrictions of remap_pfn_range(), and it doesn't complain about partial remappings. The page you insert needs to be a nice clean kernel allocation, so you can't insert arbitrary page mappings with this, but that's not what people want.

This fixes a NULL pointer reference in DRM. The SiS driver tries to allocate a big chunk of memory, but the return value is never checked. Reported in Novell bugzilla #132271: https://bugzilla.novell.com/show_bug.cgi?id=132271Signed-off-by:

Rename the EHCI "reset" routine so it better matches what it does (setup); and move the one-time data structure setup earlier, before doing anything that implicitly relies on it having been completed already.

This patch closes the IRQ race and makes various other OHCI & EHCI code path safer vs. suspend/resume. I've been able to (finally !) successfully suspend and resume various Mac models, with or without USB mouse plugged, or plugging while asleep, or unplugging while asleep etc... all without a crash. Alan, please verify the UHCI bit I did, I only verified that it builds. It's very simple so I wouldn't expect any issue there. If you aren't confident, then just drop the hunks that change uhci-hcd.c I also made the patch a little bit more "safer" by making sure the store to the interrupt register that disables interrupts is not posted before I set the flag and drop the spinlock. Without this patch, you cannot reliably sleep/wakeup any recent Mac, and I suspect PCs have some more sneaky issues too (they don't frankly crash with machine checks because x86 tend to silently swallow PCI errors but that won't last afaik, at least PCI Express will blow up in those situations, but the USB code may still misbehave).

Setting irq affinity stops working when MSI is enabled. With MSI, move_irq is empty, so we can't change irq affinity. It appears a typo in Ashok's original commit for this issue. X86_64 actually is using move_native_irq. Signed-off-by:

Access to a journaled HFS+ volume is not officially supported under Linux, so mount such a volume read-only, but users can override this behaviour using the "force" mount option. The minimum requirement to relax this check is to at least check that the journal is empty and so nothing needs to be replayed to make sure the volume is consistent. Signed-off-by:

If an external device is used for a journal, by default it will use the entire device. The reiserfs journal code allocates structures per journal block when it mounts the file system. If the journal device is too large, and memory cannot be allocated for the structures, it will continue and ultimately panic when it can't pull one off the free list. This patch handles the allocation failure gracefully and prints an error message at mount time. Changes: Updated error message to be more descriptive to the user. Discussed and approved on ReiserFS Mailing List, Nov 28. Signed-off-by:

I recently discovered a bug on PPC which causes the floating point registers to get corrupted when CONFIG_PREEMPT=y. The problem occurred while running a multi threaded Java application that does floating point. The problem could be reproduced in anywhere from 2 to 6 hours. With the patch I have included below it ran for over a week without failure. Signed-off-by:

set_page_dirty() will not cope with being handed a page * which is part of a compound page, but not the master page in that compound page. This case can occur via access_process_vm() if you attemp to write to another process's hugepage memory area using ptrace() (causing an oops or hang). This patch fixes the bug by only calling set_page_dirty() from access_process_vm() if the page is not a compound page. We already use a similar fix in bio_set_pages_dirty() for the case of direct io to hugepages. Signed-off-by:

The uid_t and gid_t fields appear to present a 32/64-bit userspace/kernel problem for some archs. This patch addresses the problem by fixing the size to the largest size for uid_t/gid_t used in the kernel. This preserves the total size of the event structure while ensuring that the layouts of the ID change event match in 32 and 64-bit kernels and applications. Signed-off-by:

This fixes a bug noticed by Paolo Galtieri and fixed for ARCH=ppc in the previous commit (ppc: fix floating point register corruption). This fixes the arch/powerpc code by adding preempt_disable/enable, and also cleans it up a bit by pulling out the code that discards any lazily-switched CPU register state into a new function, rather than having that code repeated in three places.

the patch below marks various variables const in net/; the goal is to move them to the .rodata section so that they can't false-share cachelines with things that get written to, as well as potentially helping gcc a bit with optimisations. (these were found using a gcc patch to warn about such variables) Signed-off-by:

atm_dev_deregister() removes device from atm_dev list immediately to prevent operations on a phantom device. Decision to free device based only on ->refcnt now. Remove shutdown_atm_dev() use atm_dev_deregister() instead. atm_dev_deregister() also asynchronously releases all vccs related to device. Signed-off-by:
