This fixes a race in the FRV arch's semaphore implementation. The same type of fixes were applied to the rw-semaphore implementations to fix the same races there. The race involved the on-stack record linked into the semaphore's queue by the down() executed by a process now sleeping on the semaphore going away and the sleeping task going away before the process that woke it up during up() processing had finished with those structures.

This makes switch_to() on the FRV pass through and return the previous task pointer rather than trusting to luck that it'll be left in the correct register/variable. Signed-Off-By:

One user hit problems on SMP that are caused by long standing mxser violations of the tty rules. Another report including problems with request_irq being called with locks held (legal in 2.4 but not 2.6 due to procfs). This fixes both of them Signed-off-by:

When a zone (usually DMA) has no active pages, pages_scanned (which triggers all_unreclaimable) is only incremented when scanning the active list. Make sure it's incremented for scanned cache entries too. Tested-by:

From: Steffen Thoss <thoss@de.ibm.com> From: Frank Pavlic <pavlic@de.ibm.com> qeth network driver changes: - Improve performance by omitting svs. - Use function callback mechanism to set layer 2 parameters when getting a reply for a Layer 2 command. - dev->hard_header must not be NULL when fake_ll is no set since IPv6 and Layer2 needs the default function set by network stack. - ping6 works now when running in layer 2 mode. - Save original dev->hard_header to restore it when the user doesn't want to use fake_ll anymore. - Fake ethernet header in outgoing packets. This currently works only if qeth is compiled without ipv6 support. - Add more debug information in case of failures in qeth_set_offline. - Using fake_ll with HiperSockets devices results in misaligned ip packets and thus no traffic over HiperSockets. - Start qeth_remove_device only after the qeth recovery completed.

- Diagnose 8 needs a response buffer below 2GB real storage. As the caller cannot always allocate the buffer with GFP_DMA the best solution is to rewrite cpcmd to use a bounce buffer if necessary. The old function was renamed to __cpcmd and can be called if appropriate. The early boot code does not provide kmalloc but need cpcmd functionality. These places have been converted to use __cpcmd, as the init code and data are below 2GB. - In case of an 31 bit system, cpcmd is defined as __cpcmd. - EXPORT_SYMBOL(cpcmd) moved into cpcmd.c - some whitespace fixes in cpcmd.[c/h] Signed-off-by:

This patch fixes 2 SMP deadlocks. The first is that mv64x60_read() was returning before the unlock. The second was mv64x60_modify() locks the spin lock and calls mv64x60_read() and mv64x60_write() which also lock the same spin lock. Signed-Off-By:

Since acpi_cpufreq_resume and speedstep_resume appear to return 0 upon success, it seems like the attached patch is what the desired behavior would be. Otherwise, cpufreq_resume() always prints an error and exits early if using a cpufreq_driver that supports resume. Signed-off-by:

Fix some bugs in device-mapper handling of 64-bit values, replacing dm_div_up() and dm_round_up() inlines with macros and removing some avoidable divisions of 64-bit numbers. The mirror region size is the granularity used to manage and monitor the data copying, typically 512KB, so 32 bits (of sectors) should be plenty to hold this. Taken together with the two earlier patches: "fix TB stripe data corruption" (a missing cast) and "stripe_width should be sector_t", I've now had 3 independent reports that this fixes device-mapper for devices with large stripes. Still awaiting test results for dm-crypt and dm-raid1. Signed-Off-By:
