The statistics block DMA on 5708 can be messed up occasionally on the average of about once per hour. If the user is reading the counters within one second after the corruption, the counters will be all messed up. One second later, the counters will be ok again until the next corruption occurs. The workaround is to disable the periodic statistics DMA. Instead, we manually trigger the DMA once a second in bnx2_timer(). This manual trigger of the DMA avoids the problem. As a consequence, we can only allow 0 or 1 second settings for ethtool -C statistics block. Thanks to Jean-Daniel Pauget <jd@disjunkt.com> and CaT <cat@zip.com.au> for reporting this rare problem.

Add missing code to enable DMA on 5709 A1. The bit is a no-op on A0 and therefore can be set on all 5709 chips. Signed-off-by:

For correctness, we need to wait for the MEM_INIT bit to be cleared in the BNX2_CTX_COMMAND register before proceeding. [Added return -EBUSY when the MEM_INIT bit doesn't clear, suggested by Jeff Garzik.] Signed-off-by:

There's a bug in the driver that only initializes half of the context memory on the 5708. Surprisingly, this works most of the time except for some occasional netdev watchdogs when sending a lot of 64-byte packets. The fix is to add the missing code to initialize the 2nd halves of all context memory. Signed-off-by:

This patch should get a few birds. It prevents sigaction calls from clearing TIF_SIGPENDING in other threads, which could leak -ERESTART*. And It fixes ptrace_stop not to clear it, which done at the syscall exit stop could leak -ERESTART*. It probably removes the harm from signalfd, at least assuming it never calls dequeue_signal on kernel threads that might have used block_all_signals. Signed-off-by:

The COFF zImage (for booting oldworld powermacs) wasn't being built correctly because the procedure descriptor in crt0.S for the zImage entry point wasn't declared as .globl, and therefore wasn't getting pulled in from wrapper.a by the linker. This adds the necessary .globl statement. Signed-off-by:Paul Mackerras <paulus@samba.org>

The error path in spufs_fill_dir() is broken. If d_alloc_name() or spufs_new_file() fails, spufs_prune_dir() is getting called. At this time dir->inode is not set and a NULL pointer is dereferenced by mutex_lock(). This bugfix replaces spufs_prune_dir() with a shorter version that does not touch dir->inode but simply removes all children. Signed-off-by:

We had a problem on a system with only dynamically allocated PCI buses (using of_pci_phb_driver) in combination with libata. This setup ended up having no "primary" phb, which means that pci_io_base never got initialized and all IO port numbers are 64 bit numbers, which is larger than the PIO_MASK limit. Signed-off-by:

Fix the race between checking for contexts on the runqueue and actually waking them in spu_deactive and spu_yield. The guts of spu_reschedule are split into a new helper called grab_runnable_context which shows if there is a runnable thread below a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating a specified priority and if yes removes if from the runqueue and uses it. This function is used by the new __spu_deactivate hepler shared by preemption and spu_yield to grab a new context before deactivating the old one. Signed-off-by:

Make sure the mapping_lock also protects access to the various address_space pointers used for tearing down the ptes on a spu context switch. Because unmap_mapping_range can sleep we need to turn mapping_lock from a spinlock into a sleeping mutex. Signed-off-by:

Previously, closing a SPE gang that still has contexts would trigger a WARN_ON, and leak the allocated gang. This change fixes the problem by using the gang's reference counts to destroy the gang instead. The gangs will persist until their last reference (be it context or open file handle) is gone. Also, avoid using statements with side-effects in a WARN_ON(). Signed-off-by:

Several people have reported LITE-ON LTR-48246S detection failed because SETXFER fails. It seems the device raises IRQ too early after SETXFER. This is controller independent. The same problem has been reported for different controllers. So, now we have pata_via where the controller raises IRQ before it's ready after SETXFER and a device which does similar thing. This patch makes libata always execute SETXFER via polling. As this only happens during EH, performance impact is nil. Setting ATA_TFLAG_POLLING is also moved from issue hot path to ata_dev_set_xfermode() - the only place where SETXFER can be issued. Note that ATA_TFLAG_POLLING applies only to drivers which implement SFF TF interface and use libata HSM. More advanced controllers ignore the flag. This doesn't matter for this fix as SFF TF controllers are the problematic ones. Signed-off-by:
