Some places where CLOCK_TICK_RATE may be used incorrectly: arch/arm/mach-mx3/time.c:125: __raw_writel((v / CLOCK_TICK_RATE) - 1, MXC_GPT_GPTPR); drivers/watchdog/davinci_wdt.c:103: timer_margin = (((u64)heartbeat * CLOCK_TICK_RATE) & 0xffffffff); drivers/watchdog/davinci_wdt.c:105: timer_margin = (((u64)heartbeat * CLOCK_TICK_RATE) >> 32); drivers/watchdog/ks8695_wdt.c:64: unsigned long tval = wdt_time * CLOCK_TICK_RATE; I'm not sure whether this definition is used there, but adding parentheses should be good anyway.

Third rendition of FireWire OHCI 1.0 Isochronous Receive support, using a zer-copy method similar to OHCI 1.1 which puts the IR data payload directly into the userspace buffer. The zero-copy implementation eliminates the video artifacts, audio popping, and buffer underrun problems seen with version 1 of this patch, as well as fixing a regression in OHCI 1.1 support introduced by version 2 of this patch. Successfully tested in OHCI 1.1 mode on the following chipsets: - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) - Ti TSB41AB2 (rev 01), OHCI 1.1 (PCI on SB Audigy) - Apple UniNorth 2 (rev 81), OHCI 1.1 (PowerBook G4 onboard) Successfully tested in OHCI 1.0 mode on the following chipsets: - Agere FW323 (rev 06), OHCI 1.0 (Mac Mini onboard) - Agere FW323 (rev 06), OHCI 1.0 (PCI) - Via VT6306 (rev 46), OHCI 1.0 (PCI) - NEC OrangeLink (rev 01), OHCI 1.0 (PCI) - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) The bulk of testing was done in an x86_64 system, but was also successfully sanity-tested on other systems, including a PPC(32) PowerBook G4 and an i686 EPIA M10k. Crude benchmarking (watching top during capture) puts the cpu utilization during capture on the EPIA's 1GHz Via C3 processor around 13%, which is down from 30% with the v1 code. Some implementation details: To maintain the same userspace API as dual-buffer mode, we set up two descriptors for every incoming packet. The first is an INPUT_MORE descriptor, pointing to a buffer large enough to hold just the packet's iso headers, immediately followed by an INPUT_LAST descriptor, pointing to a chunk of the userspace buffer big enough for the packet's data payload. With this setup, each incoming packet fills in these two descriptors in a manner that very closely emulates dual-buffer receive, to the point where the bulk of the handle_ir_* code is now identical between the two (and probably primed for some restructuring to share code between them). The only caveat I have at the moment is that neither of my OHCI 1.0 Via VT6307-based FireWire controllers work particularly well with this code for reasons I have yet to figure out. Signed-off-by:

This reverts commit fd6e7321, which helped up things on MIPS, but was wrong for everything else. As Ralf Baechle puts it: "It seems the whole MIPS resource managment is complicated enough (out of necessity) that only a few people actually grok it. Ioports being actually memory mapped on MIPS only makes the confusion worse, sigh." Requested-by:

PowerMac and CHRP/BriQ platforms have quirks to switch some IDE controllers from legacy mode to fully native mode. Those quirks however will not work properly anymore due to a change to the generic code to better handle legacy IDE resources. This fixes it by moving those quirk to "early" quirks (so they run before resources are probed for the devices) and clearing all BARs after the conversion to force a reallocation of sane values.

The recent I_LOCK->I_SYNC changes mistakenly changed xfs_ichgtime to look at I_SYNC instead of I_LOCK. This was incorrect and prevents newly created inodes from moving to the dirty list. Change this to the correct check which is for I_NEW, not I_LOCK or I_SYNC so that behaviour is correct. SGI-PV: 974225 SGI-Modid: xfs-linux-melb:xfs-kern:30204a Signed-off-by:

The radix tree based inode caches did away with the inode cluster hashes, replacing them with a bunch of masking and gang lookups on the radix tree. This masking got broken when moving the code to per-ag radix trees and indexing by agino # rather than straight inode number. The result is clustered inode writeback does not cluster and things can go extremely slowly when there are lots of inodes to write. Fix it up by comparing the agino # of the inode we just looked up to the index of the cluster we are looking for. Tested-by:

- calculation of 'page_count' was incorrect as it did not consider the offset of 'mem' into the first page. The logic to bump 'page_count' didn't work if 'len' was <= PAGE_CACHE_SIZE (ie offset = 3k, len = 2k). - setting b_buffer_length to 'len' is incorrect if 'offset' is > 0. Set it to the total length of the buffer. - I suspect that passing a non-aligned address into mem_to_page() for the first page may have been causing issues - don't know but just tidy up that code anyway.

- sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]() - remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

Jan Altenberg <jan.altenberg@linutronix.de> reported that building with redirected input like this failed: make O=dir oldconfig bzImage < /dev/null The problem were caused by a make silentoldconfig being run before oldconfig and with a non-recent .config the build failed because silentoldconfig requires non-redirected stdin.

-
Tejun Heo authored
Spurious NCQ completion detection implemented in ahci was incorrect. On AHCI receving and processing FISes and raising interrupts are not interlocked and spurious interrupts are expected. For example, if an interrupt occurs while interrupt handler is running and the running interrupt handler handles the event the new IRQ indicated, after IRQ handler finishes, it will be executed again because IRQ pending bit is set by the new interrupt but there won't be anything to process. Please read the following message for more information. http://article.gmane.org/gmane.linux.ide/26012 This patch... * Removes all spurious IRQ whining from ahci. Spurious NCQ completion detection was completely wrong. Spurious D2H Register FIS taught us that some early drives send spurious D2H Register FIS with I bit set while NCQ commands are in progress but none of recent drives does that and even the ones which show such behavior can do NCQ fine. * Kills all NCQ blacklist entries which were added because of spurious NCQ completions. I tracked down each commit and verified all removed ones are actually added because of spurious completions. WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive not only had spurious NCQ completions but also is slow on sequential data transfers if NCQ is enabled. Maxtor 7V300F0 was added by 0e3dbc01 from Alan Cox. I can only find evidences that the drive only had troubles with spuruious completions by searching the mailing list. This entry needs to be verified and removed if it doesn't have other NCQ related problems. Signed-off-by:
