* | ARM: 5701/1: ARM: copy_page.S: take into account the size of the cache lineKirill A. Shutemov2009-09-151-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimized version of copy_page() was written with assumption that cache line size is 32 bytes. On Cortex-A8 cache line size is 64 bytes. This patch tries to generalize copy_page() to work with any cache line size if cache line size is multiple of 16 and page size is multiple of two cache line size. After this optimization we've got ~25% speedup on OMAP3(tested in userspace). There is test for kernelspace which trigger copy-on-write after fork(): #include <stdlib.h> #include <string.h> #include <unistd.h> #define BUF_SIZE (10000*4096) #define NFORK 200 int main(int argc, char **argv) { char *buf = malloc(BUF_SIZE); int i; memset(buf, 0, BUF_SIZE); for(i = 0; i < NFORK; i++) { if (fork()) { wait(NULL); } else { int j; for(j = 0; j < BUF_SIZE; j+= 4096) buf[j] = (j & 0xFF) + 1; break; } } free(buf); return 0; } Before optimization this test takes ~66 seconds, after optimization takes ~56 seconds.

(2) A missing return in keyring_gc() meant that under certain circumstances, the keyring semaphore would be unlocked twice. (3) The key serial tree iterator (key_garbage_collector()) part of the garbage collector has been modified to: (a) Complete each scan of the keyrings before setting the new timer. (b) Only set the new timer for keys that have yet to expire. This means that the new timer is now calculated correctly, and the gc doesn't get into a loop continually scanning for keys that have expired, and preventing other things from happening, like RCU cleaning up the old keyring contents. (c) Perform an extra scan if any keys were garbage collected in this one as a key might become garbage during a scan, and (b) could mean we don't set the timer again. (4) Made key_schedule_gc() take the time at which to do a collection run, rather than the time at which the key expires. This means the collection of dead keys (key type unregistered) can happen immediately. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>

This fixes a bug on s390, where we allow both config options HIBERNATION and MEMORY_HOTPLUG, so that we also have a ZONE_MOVABLE here. We only allow hibernation if no memory hotplug operation was performed, so in fact both features can only be used exclusively, but this way we don't need 2 differently configured (distribution) kernels. If we have an unpopulated ZONE_MOVABLE, we allow hibernation but run into a BUG_ON() in memory_bm_test/set/clear_bit() because hibernation code iterates through all zones, not only the populated zones, in several places. For example, swsusp_free() does for_each_zone() and then checks for pfn_valid(), which is true even if the zone is not populated, resulting in a BUG_ON() later because the pfn cannot be found in the memory bitmap. Replacing all occurences of for_each_zone() in hibernation code with for_each_populated_zone() would fix this issue.

The approach here is based on the (experimental) observation that we can't free more page frames than the sum of: * global_page_state(NR_SLAB_RECLAIMABLE) * global_page_state(NR_ACTIVE_ANON) * global_page_state(NR_INACTIVE_ANON) * global_page_state(NR_ACTIVE_FILE) * global_page_state(NR_INACTIVE_FILE) minus * global_page_state(NR_FILE_MAPPED) Namely, if this number is subtracted from the number of saveable pages in the system, we get a good estimate of the minimum reasonable size of a hibernation image.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the hibernation code is now going to use allocations of memory to make enough room for the image, it can also use the page frames allocated at this stage as image page frames. The low-level hibernation code needs to be rearranged for this purpose, but it allows us to avoid freeing a great number of pages and allocating these same pages once again later, so it generally is worth doing.

The callbacks are weak symbols that architecture specific code can override. Allows Runtime PM even though CONFIG_PM_SLEEP=n.

| * | | | | PM: Introduce core framework for run-time PM of I/O devices (rev. 17)Rafael J. Wysocki2009-08-2310-11/+1689

Add device run-time PM fields to 'struct dev_pm_info' and device run-time PM callbacks to 'struct dev_pm_ops'. Introduce a run-time PM workqueue and define some device run-time PM helper functions at the core level. Document all these things. Special thanks to Alan Stern for his help with the design and multiple detailed reviews of the pereceding versions of this patch and to Magnus Damm for testing feedback. Signed-off-by: Rafael J.
