If userspace supplies an invalid pointer to a read() of an inotify instance, the inotify device's event list mutex is unlocked twice. This causes an unbalance which effectively leaves the data structure unprotected, and we can trigger oopses by accessing the inotify instance from different tasks concurrently.

Move fuse_copy_finish() to before calling fuse_notify_poll_wakeup(). This is not a big issue because fuse_notify_poll_wakeup() should be atomic, but it's cleaner this way, and later uses of notification will need to be able to finish the copying before performing some actions. Signed-off-by:

In the absence of PAT, PAGE_KERNEL_WC ends up mapping to a memory type that gets UC behavior even in the presence of a WC MTRR covering the area in question. By swapping to PAGE_KERNEL_UC_MINUS, we can get the actual behavior the caller wanted (WC if you can manage it, UC otherwise). This recovers the 40% performance improvement of using WC in the DRM to upload vertex data. Signed-off-by:

the RDC and ELAN platforms use slighly different PIT clocks, resulting in a timex.h hack that changes PIT_TICK_RATE during build time. But if a tester enables any of these platform support .config options, the PIT will be miscalibrated on standard PC platforms. So use one frequency - in a subsequent patch we'll add a quirk to allow x86 platforms to define different PIT frequencies. Signed-off-by:

This is due to pgtable_page_ctor() doing the spin_lock_init(&page->ptl) which is overlaid with the {private, mapping} struct. union { struct { unsigned long private; struct address_space *mapping; }; spinlock_t ptl; struct kmem_cache *slab; struct page *first_page; }; Normally the spinlock is small enough to not stomp on page->mapping, but PREEMPT_RT=y has huge 'spin'locks. But lockdep kernels should also be able to trigger this splat, as the lock tracking code grows the spinlock to cover page->mapping. The obvious fix is calling pgtable_page_dtor() like the regular pte free path __pte_free_tlb() does. It seems all architectures except x86 and nm10300 already do this, and nm10300 doesn't seem to use pgtable_page_ctor(), which suggests it doesn't do SMP or simply doesnt do MMU at all or something.

Precreate stop_machine threads in case the machine supports ETR/STP. Otherwise we might deadlock if a time sync operation gets scheduled and the creation of stop_machine threads would cause disk I/O. This is just the minimal fix. The real fix would be to only precreate stop_machine threads if ETR/STP is actually used. But that would be a rather large and complicated patch. Signed-off-by:

On (initial) cpu hotplug the lowcore values for user_timer and system_timer don't get initialized like they would get on each process schedule. On initial start of secondary cpus this leads to the situation where per thread user/system_timer values are larger than the corresponding contents of the lowcore. When later calculating time spent in user/system context the result can be negative. So for cpu hotplug we should manually initialize lowcore values.

When 31 bit user space programs call sigaltstack on a 64 bit Linux OS, the system call returns -1 with errno=EFAULT. The 31 bit pointer passed to the system call is extended to 64 bit, but the high order bits are not set to zero. The kernel detects the invalid user space pointer and returns -EFAULT. To solve the problem, sys32_sigaltstack_wrapper() instead of sys32_sigaltstack() has to be called. The wrapper function sets the high order bits to zero. Signed-off-by:
