Patch from Ben Dooks Avoid the possiblity that if the board is using a 16.9334 or higher crystal with a high PLL multiplier, then the pll value could overflow the capability of an int.

This introduces a limit parameter to the core bootmem allocator; The new parameter indicates that physical memory allocated by the bootmem allocator should be within the requested limit. We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit, alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit is the only api used for swiotlb. The existing alloc_bootmem_low_pages() api could instead have been changed and made to pass right limit to the core allocator. But that would make the patch more intrusive for 2.6.14, as other arches use alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a cleanup. With this, swiotlb gets memory within 4G for both x86_64 and ia64 arches.

In drivers/acpi/glue.c the address of an integer is cast to the address of an unsigned long. This breaks on systems where a long is larger than an int --- for a start the int can be misaligned; for a second the assignment through the pointer will overwrite part of the next variable.

The PF_NOFREEZE process flag should not be inherited when a thread is forked. This patch (as585) removes the flag from the child. This problem is starting to show up more and more as drivers turn to the kthread API instead of using kernel_thread(). As a result, their kernel threads are now children of the kthread worker instead of modprobe, and they inherit the PF_NOFREEZE flag. This can cause problems during system suspend; the kernel threads are not getting frozen as they ought to be.

由 NeilBrown 提交于
The main problem fixes is that in certain situations stopping md arrays may take longer than you expect, or may require multiple attempts. This would only happen when resync/recovery is happening. This patch fixes three vaguely related bugs. 1/ The recent change to use kthreads got the setting of the process name wrong. This fixes it. 2/ The recent change to use kthreads lost the ability for md threads to be signalled with SIG_KILL. This restores that. 3/ There is a long standing bug in that if: - An array needs recovery (onto a hot-spare) and - The recovery is being blocked because some other array being recovered shares a physical device and - The recovery thread is killed with SIG_KILL Then the recovery will appear to have completed with no IO being done, which can cause data corruption. This patch makes sure that incomplete recovery will be treated as incomplete. Note that any kernel affected by bug 2 will not suffer the problem of bug 3, as the signal can never be delivered. Thus the current 2.6.14-rc kernels are not susceptible to data corruption. Note also that if arrays are shutdown (with "mdadm -S" or "raidstop") then the problem doesn't occur. It only happens if a SIGKILL is independently delivered as done by 'init' when shutting down.

Changes all spinlocks that can be held during an irq handler to disable interrupts while the lock is held. Changes spin_[un]lock_irq to use the irqsave/irqrestore variants for robustness and readability. In raw1394.c:handle_iso_listen(), don't grab host_info_lock at all -- we're not accessing host_info_list or host_count, and holding this lock while trying to tasklet_kill the iso tasklet this can cause an ABBA deadlock if ohci:dma_rcv_tasklet is running and tries to grab host_info_lock in raw1394.c:receive_iso.

hugetlbfs allows truncation of its files (should it?), but hugetlb.c often forgets that: crashes and misaccounting ensue. copy_hugetlb_page_range better grab the src page_table_lock since we don't want to guess what happens if concurrently truncated. unmap_hugepage_range rss accounting must not assume the full range was mapped. follow_hugetlb_page must guard with page_table_lock and be prepared to exit early. Restyle copy_hugetlb_page_range with a for loop like the others there.

由 Roland McGrath 提交于
Oleg Nesterov reported an SMP deadlock. If there is a running timer tracking a different process's CPU time clock when the process owning the timer exits, we deadlock on tasklist_lock in posix_cpu_timer_del via exit_itimers. That code was using tasklist_lock to check for a race with __exit_signal being called on the timer-target task and clearing its ->signal. However, there is actually no such race. __exit_signal will have called posix_cpu_timers_exit and posix_cpu_timers_exit_group before it does that. Those will clear those k_itimer's association with the dying task, so posix_cpu_timer_del will return early and never reach the code in question. In addition, posix_cpu_timer_del called from exit_itimers during execve or directly from timer_delete in the process owning the timer can race with an exiting timer-target task to cause a double put on timer-target task struct. Make sure we always access cpu_timers lists with sighand lock held.

由 Seth, Rohit 提交于
The hugetlb pages are currently pre-faulted. At the time of mmap of hugepages, we populate the new PTEs. It is possible that HW has already cached some of the unused PTEs internally. These stale entries never get a chance to be purged in existing control flow. This patch extends the check in page fault code for hugepages. Check if a faulted address falls with in size for the hugetlb file backing it. We return VM_FAULT_MINOR for these cases (assuming that the arch specific page-faulting code purges the stale entry for the archs that need it).

Reported by: Bob Tracy <rct@gherkin.frus.com> "...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which I'm using the Vesa FB driver. When the machine has been idle for some time and the driver attempts to powerdown the display, rather than the display going blank, it goes gray with several strange lines. When I hit the "shift" key or other-wise wake up the display, the old video state is not fully restored..." vesafb recently added a blank method which has only 2 states, powerup and powerdown. The powerdown state is used for all blanking levels, but in his case, powerdown does not work correctly for higher levels of display powersaving. Thus, for intermediate power levels, use software blanking, and use only hardware blanking for an explicit powerdown.

When interrupt 0 occur: o if CONFIG_CPU_IXP46X is not set, "subs" will set the Z flag and return o if CONFIG_CPU_IXP46X is set, codes in upper interrupt handling will be trigerred. But since this is not supper interrupt, the "cmp" in the upper interrupt handling portion will set the Z flag and return Signed-off-by: NKenneth Tan <chong.yin.tan@intel.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

lock_kiocb() was introduced to serialize retrying and cancellation. In the process of doing so it tried to sleep waiting for KIF_LOCKED while holding the ctx_lock spinlock. Recent fixes have ensured that multiple concurrent retries won't be attempted for a given iocb. Cancel has other problems and has no significant in-tree users that have been complaining about it. So for the immediate future we'll revert sleeping with the lock held and will address proper cancellation and retry serialization in the future.
