57b30ae7 ("workqueue: reimplement cancel_delayed_work() using try_to_grab_pending()") made cancel_delayed_work() always return %true unless someone else is also trying to cancel the work item, which is broken - if the target work item is idle, the return value should be %false. try_to_grab_pending() indicates that the target work item was idle by zero return value. Use it for return. Note that this brings cancel_delayed_work() in line with __cancel_work_timer() in return value handling.

由 John Johansen 提交于
BugLink: http://bugs.launchpad.net/bugs/1056078 Profile replacement can cause long chains of profiles to build up when the profile being replaced is pinned. When the pinned profile is finally freed, it puts the reference to its replacement, which may in turn nest another call to free_profile on the stack. Because this may happen for each profile in the replacedby chain this can result in a recusion that causes the stack to overflow. Break this nesting by directly walking the chain of replacedby profiles (ie. use iteration instead of recursion to free the list). This results in at most 2 levels of free_profile being called, while freeing a replacedby chain.

If none of the elements in scrubrates[] matches, this loop will cause __amd64_set_scrub_rate() to incorrectly use the n+1th element. As the function is designed to use the final scrubrates[] element in the case of no match, we can fix this bug by simply terminating the array search at the n-1th element. Boris: this code is fragile anyway, see here why: http://marc.info/?l=linux-kernel&m=135102834131236&w=2 It will be rewritten more robustly soonish.

The tile tool chain uses the .eh_frame information for backtracing. The vmlinux build drops any .eh_frame sections at link time, but when present in kernel modules, it causes a module load failure due to the presence of unsupported pc-relative relocations. When compiling to use compiler feedback support, the compiler by default omits .eh_frame information, so we don't see this problem. But when not using feedback, we need to explicitly suppress the .eh_frame. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com> Cc: stable@vger.kernel.org

[Originally sent by Ulf as two changes, squashed down into one with a redone changelog, thanks to Russell King for analysis. -- broonie] This reverts commit 688723 (spi/pl022: enable runtime PM) and commit 2fb30d (spi/pl022: fix spi-pl022 pm enable at probe). Commit "spi/pl022: enable runtime PM" introduced runtime PM issues as it interacted badly with the work Russell King had done to move core runtime PM handling into the bus. Due to that commit, "spi/pl022: fix spi-pl022 pm enable at probe" was merged to fix part of those issues. Instead of adding another fix, let's clean up and revert everything back to when it was already fine.

The irqdomain semantics were supposed to be such that a linear domain would be used if the passed first_irq was zero or negative, but I got it wrong so only passing zero as first_irq will work properly.

Since in the DT case, the linear domain path will not allocate descriptors for the IRQs, we need to use irq_create_mapping() for mapping hwirqs to Linux IRQs, so these descriptors get created on-the-fly in this case. ChangeLog v1->v2: - Just use irq_create_mapping() in the .to_irq function since this is called before unmasking or enabling any interrupt lines, so irq_find_mapping() should be sufficient for the IRQ handler function.

In theory, that function could release the lru lock between checking for bo on ddestroy list and a successful reserve if the bo was already reserved, and the function was called with waiting reserves allowed. However, all current reservers of a bo on the ddestroy list would atomically take the bo off the list after a successful reserve so this race should not have been hit, so no need to backport for stable. This patch also fixes a case found by Maarten Lankhorst where ttm_mem_evict_first called with no_wait_gpu would incorrectly spin waiting for bo idle if trying to evict a busy buffer that also sits on the ddestroy list.
