f50bf2b Paul Mundt 03 July 2009, 06:45:56 UTC video: sm501fb: Early initialization of mm_lock mutex. Commit 537a1bf059fa312355696fa6db80726e655e7f17 (fbdev: add mutex for fb_mmap locking) introduces a ->mm_lock mutex for protecting smem assignments. Unfortunately in the case of sm501fb these happen quite early in the initialization code, well before the mutex_init() that takes place in register_framebuffer(), leading to: Badness at kernel/mutex.c:207 Pid : 1, Comm: swapper CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273) PC is at __mutex_lock_slowpath+0x72/0x1bc PR is at __mutex_lock_slowpath+0x66/0x1bc ... matroxfb appears to have the same issue and has solved it with an early mutex_init(), so we do the same for sm501fb.

ab0fd1d Tejun Heo 03 July 2009, 10:56:18 UTC block: don't merge requests of different failfast settings Block layer used to merge requests and bios with different failfast settings. This caused regular IOs to fail prematurely when they were merged into failfast requests for readahead. Niel Lambrechts could trigger the problem semi-reliably on ext4 when resuming from STR. ext4 uses readahead when reading inodes and combined with the deterministic extra SATA PHY exception cycle during resume on the specific configuration, non-readahead inode read would fail causing ext4 errors. Please read the following thread for details. http://lkml.org/lkml/2009/5/23/21 This patch makes block layer reject merging if the failfast settings don't match. This is correct but likely to lower IO performance by preventing regular IOs from mingling into surrounding readahead requests. Changes to allow such mixed merges and handle errors correctly will be added later.

b59e64d Hannes Reinecke 02 July 2009, 20:02:06 UTC cciss: Ignore stale commands after reboot When doing an unexpected shutdown like kexec the cciss firmware might still have some commands in flight, which it is trying to complete. The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

cad9bc6 Yong Zhang 01 July 2009, 01:35:39 UTC MIPS: 64-bit: Fix o32 core dump If an o32 process generates a core dump on a 64 bit kernel, the core file will not be correctly recognized. This is because ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS are not correctly defined for o32 and will use the default register set which would be CONFIG_64BIT in asm/elf.h. So we'll switch to use the right register defines in this situation by checking for WANT_COMPAT_REG_H and use the right defines of ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

ea4bbfd matthieu castet 30 June 2009, 21:04:55 UTC MIPS: BC47xx: Fix SSB irq setup The current ssb irq setup in ssb_mipscore_init has the problem that it configures some device on some irq without checking that the irq is not taken by an other device. For example in my case PCI host is on irq 0 and IPSEC on irq 3. The current code: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This causes a problem described in [1]. This patch tries to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0. The previous example becomes: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host: - irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC I also added some code to print the irq configuration after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.

Cavium OCTEON falls into this category. We would still like to use the optimized implementation, so since we have already checked for CONFIG_CPU_MIPSR2, checking for CONFIG_64BIT instead of CONFIG_CPU_MIPS64_R2 is sufficient.

033a666 David Howells 02 July 2009, 13:35:32 UTC NFSD: Don't hold unrefcounted creds over call to nfsd_setuser() nfsd_open() gets an unrefcounted pointer to the current process's effective credentials at the top of the function, then calls nfsd_setuser() via fh_verify() - which may replace and destroy the current process's effective credentials - and then passes the unrefcounted pointer to dentry_open() - but the credentials may have been destroyed by this point. Instead, the value from current_cred() should be passed directly to dentry_open() as one of its arguments, rather than being cached in a variable. Possibly fh_verify() should return the creds to use.

84be31b Grant Grundler 01 June 2009, 00:20:23 UTC parisc: fix "delay!" timer handling Rewrote timer_interrupt() to properly handle the "delayed!" case. If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer. Tested on A500 (550 Mhz PA8600).

If a tree block isn't referenced by its owner tree, full backrefs must be used for the pointers in it. When a tree block loses its owner tree's reference, backrefs for the pointers in it should be updated to full backrefs. Current btrfs_drop_snapshot misses the code that updates backrefs, so it's unsafe for general use. This patch adds backrefs update code to btrfs_drop_snapshot. It isn't a problem in the restricted form btrfs_drop_snapshot is used today, but for general snapshot deletion this update is required.
