* uml: deal with host time going backwardsJeff Dike2008-06-061-0/+7
| | | | | | | | | | | | Protection against the host's time going backwards (eg, ntp activity on the host) by keeping track of the time at the last tick and if it's greater than the current time, keep time stopped until the host catches up.

* nommu: fix kobjsize() for SLOB and SLUBPaul Mundt2008-06-061-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kobjsize() has been abusing page->index as a method for sorting out compound order, which blows up both for page cache pages, and SLOB's reuse of the index in struct slob_page. Presently we are not able to accurately size arbitrary pointers that don't come from kmalloc(), so the best we can do is sort out the compound order from the head page if it's a compound page, or default to 0-order if it's impossible to ksize() the object. Obviously this leaves quite a bit to be desired in terms of object sizing accuracy, but the behaviour is unchanged over the existing implementation, while fixing the page->index oopses originally reported here: http://marc.info/?l=linux-mm&m=121127773325245&w=2 Accuracy could also be improved by having SLUB and SLOB both set PG_slab on ksizeable pages, rather than just handling the __GFP_COMP cases irregardless of the PG_slab setting, as made possibly with Pekka's patches: http://marc.info/?l=linux-kernel&m=121139439900534&w=2 http://marc.info/?l=linux-kernel&m=121139440000537&w=2 http://marc.info/?l=linux-kernel&m=121139440000540&w=2 This is primarily a bugfix for nommu systems for 2.6.26, with the aim being to gradually kill off kobjsize() and its particular brand of object abuse entirely.

* eCryptfs: remove unnecessary page decrypt callMichael Halcrow2008-06-062-24/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The page decrypt calls in ecryptfs_write() are both pointless and buggy. Pointless because ecryptfs_get_locked_page() has already brought the page up to date, and buggy because prior mmap writes will just be blown away by the decrypt call. This patch also removes the declaration of a now-nonexistent function ecryptfs_write_zeros(). Thanks to Eric Sandeen and David Kleikamp for helping to track this down. Eric said: fsx w/ mmap dies quickly ( < 100 ops) without this, and survives nicely (to millions of ops+) with it in place.

* md: fix prexor vs sync_request raceDan Williams2008-06-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the initial array synchronization process there is a window between when a prexor operation is scheduled to a specific stripe and when it completes for a sync_request to be scheduled to the same stripe. When this happens the prexor completes and the stripe is unconditionally marked "insync", effectively canceling the sync_request for the stripe. Prior to 2.6.23 this was not a problem because the prexor operation was done under sh->lock. The effect in older kernels being that the prexor would still erroneously mark the stripe "insync", but sync_request would be held off and re-mark the stripe as "!in_sync". Change the write completion logic to not mark the stripe "in_sync" if a prexor was performed. The effect of the change is to sometimes not set STRIPE_INSYNC. The worst this can do is cause the resync to stall waiting for STRIPE_INSYNC to be set. If this were happening, then STRIPE_SYNCING would be set and handle_issuing_new_read_requests would cause all available blocks to eventually be read, at which point prexor would never be used on that stripe any more and STRIPE_INSYNC would eventually be set. echo repair > /sys/block/mdN/md/sync_action will correct arrays that may have lost this race.

| * [ARM] fix AT91 include loopsRussell King2008-06-011-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AT91 has one include loop in its header files: include/asm-arm/io.h <- include/asm-arm/arch-at91/io.h <- include/asm-arm/io.h Circular include dependencies are dangerous since they can result in inconsistent definitions being provided to other code, especially if '#ifndef' constructs are used. Solve this by removing the offending includes. Built tested using my AT91 configuration. Acked-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | Fairly simple. "dev_use" was being allocated as a zero length array because of bad math on 64-bit systems, causing a crash in find_first_zero_bit().

This problem can probably be worked around in other ways as well, i went for the minimal fix. Obviously, the kconfig tool should be fixed, it is not reasonable to expect driver authors to do manual dependency resolution (that kconfig itself already does) and uglify the Kconfig files. The kconfig tool did nothing to warn about this situation and did not prevent this faulty .config from being constructed.
