2012-04-24USB: EHCI: fix crash during suspend on ASUS computersAlan Stern
This patch (as1545) fixes a problem affecting several ASUS computers: The machine crashes or corrupts memory when going into suspend if the ehci-hcd driver is bound to any controllers. Users have been forced to unbind or unload ehci-hcd before putting their systems to sleep. After extensive testing, it was determined that the machines don't like going into suspend when any EHCI controllers are in the PCI D3 power state. Presumably this is a firmware bug, but there's nothing we can do about it except to avoid putting the controllers in D3 during system sleep. The patch adds a new flag to indicate whether the problem is present, and avoids changing the controller's power state if the flag is set. Runtime suspend is unaffected; this matters only for system suspend. However as a side effect, the controller will not respond to remote wakeup requests while the system is asleep. Hence USB wakeup is not functional -- but of course, this is already true in the current state of affairs. This fixes Bugzilla #42728.

2012-04-24iwlwifi: fix hardware queue programmingJohannes Berg
Newer devices have 20 (5000 series) or 30 (6000 series) hardware queues, rather than the 16 that 4965 had. This was added to the driver a long time ago, but improperly: the queue registers for the higher queues aren't just continuations of the registers for the first 16 queues, they are in other places. Therefore, the hardware would lock up when trying to activate queue 16 or above and the device would have to be restarted. Thanks goes to Emmanuel who identified this and told me how the queue programming should be done. Note that we don't use queues 20 and higher today and doing so needs more work than this.

2012-04-24GFS2: Instruct DLM to avoid queue convert slowdownBob Peterson
This patch instructs DLM to prevent an "in place" conversion, where the lock just stays on the granted queue, and instead forces the conversion to the back of the convert queue. This is done on upward conversions only. This is useful in cases where, for example, a lock is frequently needed in PR on one node, but another node needs it temporarily in EX to update it. This may happen, for example, when the rindex is being updated by gfs2_grow. The gfs2_grow needs to have the lock in EX, but the other nodes need to re-read it to retrieve the updates. The glock is already granted in PR on the non-growing nodes, so this prevents them from continually re-granting the lock in PR, and forces the EX from gfs2_grow to go through.

2012-04-23mm: fix s390 BUG by __set_page_dirty_no_writeback on swapHugh Dickins
Mel reports a BUG_ON(slot == NULL) in radix_tree_tag_set() on s390 3.0.13: called from __set_page_dirty_nobuffers() when page_remove_rmap() tries to transfer dirty flag from s390 storage key to struct page and radix_tree. That would be because of reclaim's shrink_page_list() calling add_to_swap() on this page at the same time: first PageSwapCache is set (causing page_mapping(page) to appear as &swapper_space), then page->private set, then tree_lock taken, then page inserted into radix_tree - so there's an interval before taking the lock when the radix_tree slot is empty. We could fix this by moving __add_to_swap_cache()'s spin_lock_irq up before the SetPageSwapCache. But a better fix is simply to do what's five years overdue: Ken Chen introduced __set_page_dirty_no_writeback() (if !PageDirty TestSetPageDirty) for tmpfs to skip all the radix_tree overhead, and swap is just the same - it ignores the radix_tree tag, and does not participate in dirty page accounting, so should be using __set_page_dirty_no_writeback() too. s390 testing now confirms that this does indeed fix the problem.

2012-04-24md: fix possible corruption of array metadata on shutdown.NeilBrown
commit c744a65c1e2d59acc54333ce8 md: don't set md arrays to readonly on shutdown. removed the possibility of a 'BUG' when data is written to an array that has just been switched to read-only, but also introduced the possibility that the array metadata could be corrupted. If, when md_notify_reboot gets the mddev lock, the array is in a state where it is assembled but hasn't been started (as can happen if the personality module is not available, or in other unusual situations), then incorrect metadata will be written out making it impossible to re-assemble the array. So only call __md_stop_writes() if the array has actually been activated. This patch is needed for any stable kernel which has had the above commit applied.

2012-04-24md: don't call ->add_disk unless there is good reason.NeilBrown
Commit 7bfec5f35c68121e7b18 md/raid5: If there is a spare and a want_replacement device, start replacement. cause md_check_recovery to call ->add_disk much more often. Instead of only when the array is degraded, it is now called whenever md_check_recovery finds anything useful to do, which includes updating the metadata for clean<->dirty transition. This causes unnecessary work, and causes info messages from ->add_disk to be reported much too often. So refine md_check_recovery to only do any actual recovery checking (including ->add_disk) if MD_RECOVERY_NEEDED is set.

2012-04-23asm-generic: Allow overriding clock_t and add attributes to siginfo_tH. Peter Anvin
For the particular issue of x32, which shares code with i386 in the handling of compat_siginfo_t, the use of a 64-bit clock_t bumps the sigchld structure out of alignment, which triggers a messy cascade of padding. This was already handled on the kernel compat side, but it needs handling on the user space side, which uses the generic header. To make that possible: 1. Allow __kernel_clock_t to be overridden in struct siginfo; 2. Allow there to be attributes added to struct siginfo. Reported-by: H.J. Lu <hjl.rools@gmail.com> Cc: Bruce J.

2012-04-23x86, acpi: Call acpi_enter_sleep_state via an asmlinkage C function from ↵Konrad Rzeszutek Wilk
assembler With commit a2ef5c4fd44ce3922435139393b89f2cce47f576 "ACPI: Move module parameter gts and bfs to sleep.c" the wake_sleep_flags is required when calling acpi_enter_sleep_state. The assembler code in wakeup_*.S did not do that. One solution is to call it from assembler and stick the wake_sleep_flags on the stack (for 32-bit) or in %esi (for 64-bit). hpa and rafael both suggested however to create a wrapper function to call acpi_enter_sleep_state and call said wrapper function ("acpi_enter_s3") from assembler. For 32-bit, the acpi_enter_s3 ends up looking as so: push %ebp mov %esp,%ebp sub $0x8,%esp movzbl 0xc1809314,%eax [wake_sleep_flags] movl $0x3,(%esp) mov %eax,0x4(%esp) call 0xc12d1fa0 <acpi_enter_sleep_state> leave ret And 64-bit: movzbl 0x9afde1(%rip),%esi [wake_sleep_flags] push %rbp mov $0x3,%edi mov %rsp,%rbp callq 0xffffffff812e9800 <acpi_enter_sleep_state> leaveq retq Reviewed-by: H.
