2010-01-28cdc_ether: Partially revert "usbnet: Set link down initially ..."Ben Hutchings
Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down initially for drivers that update link state") changed the initial link state in cdc_ether and other drivers based on the understanding that the devices they support generate link change interrupts. However, this is optional in the CDC Ethernet protocol, and two users have reported in <http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state for their devices remains down. Therefore, revert the change in cdc_ether. Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Tested-by: Avi Rozen <avi.rozen@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-01-28Btrfs: check total number of devices when removing missingJosef Bacik
If you have a disk failure in RAID1 and then add a new disk to the array, and then try to remove the missing volume, it will fail. The reason is the sanity check only looks at the total number of rw devices, which is just 2 because we have 2 good disks and 1 bad one. Instead check the total number of devices in the array to make sure we can actually remove the device. Tested this with a failed disk setup and with this test we can now run btrfs-vol -r missing /mount/point and it works fine.

2010-01-28Btrfs: check return value of open_bdev_exclusive properlyJosef Bacik
Hit this problem while testing RAID1 failure stuff. open_bdev_exclusive returns ERR_PTR(), not NULL. So change the return value properly. This is important if you accidently specify a device that doesn't exist when trying to add a new device to an array, you will panic the box dereferencing bdev.

2010-01-28Btrfs: do not mark the chunk as readonly if in degraded modeJosef Bacik
If a RAID setup has chunks that span multiple disks, and one of those disks has failed, btrfs_chunk_readonly will return 1 since one of the disks in that chunk's stripes is dead and therefore not writeable. So instead if we are in degraded mode, return 0 so we can go ahead and allocate stuff. Without this patch all of the block groups in a RAID1 setup will end up read-only, which will mean we can't add new disks to the array since we won't be able to make allocations.

2010-01-28Btrfs: run orphan cleanup on default fs rootJosef Bacik
This patch revert's commit 6c090a11e1c403b727a6a8eff0b97d5fb9e95cb5 Since it introduces this problem where we can run orphan cleanup on a volume that can have orphan entries re-added. Instead of my original fix, Yan Zheng pointed out that we can just revert my original fix and then run the orphan cleanup in open_ctree after we look up the fs_root.

2010-01-28Btrfs: Add mount -o compress-forceChris Mason
The default btrfs mount -o compress mode will quickly back off compressing a file if it notices that compression does not reduce the size of the data being written. This can save considerable CPU because all future writes to the file go through uncompressed. But some files are both very large and have mixed data stored in them. In that case, we want to add the ability to always try compressing data before writing it. This commit adds mount -o compress-force. A later commit will add a new inode flag that does the same thing.

We have to properly decrease bi_size in order to merge_bvec_fn return right result. Otherwise this result in false merge rejects for two absolutely valid bio_vecs. This may cause significant performance penalty for example fs_block_size == 1k and block device is raid0 with small chunk_size = 8k.

2010-01-28hw_breakpoints: Release the bp slot if arch_validate_hwbkpt_settings() fails.Mahesh Salgaonkar
On a given architecture, when hardware breakpoint registration fails due to un-supported access type (read/write/execute), we lose the bp slot since register_perf_hw_breakpoint() does not release the bp slot on failure. Hence, any subsequent hardware breakpoint registration starts failing with 'no space left on device' error. This patch introduces error handling in register_perf_hw_breakpoint() function and releases bp slot on error.

2010-01-28MIPS: PowerTV: Fix support for timer interrupts with > 64 external IRQsDavid VomLehn
The MIPS processor is limited to 64 external interrupt sources. Using a greater number without IRQ sharing requires reading platform-specific registers. On such platforms, reading the IntCtl register to determine which interrupt corresponds to a timer interrupt will not work. On MIPSR2 systems there is a solution - the TI bit in the Cause register, specifically indicates that a timer interrupt has occured. This patch uses that bit to detect interrupts for MIPSR2 processors, which may be expected to work regardless of how the timer interrupt may be routed in the hardware.

POSIX requires $((<expression>)) arithmetic in sh only to have long arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit. I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is 0xffffffff94100000, and for an example 4MiB kernel VMLINUZ_LOAD_ADDRESS is made out to be: ---- alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' ffffffff94500000 alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))' 80000000003fffff ---- The former is obviously correct whilst the later breaks things royally. Fortunately working with only the lower 32bit's works for both bash and dash: ---- $ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 $ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))' 94500000 ---- So, we can split the original 64bit string to two parts, and only calculate the low 32bit part, which is big enough (1GiB kernel sizes anyone?) for a normal Linux kernel image file, now, we calculate the VMLINUZ_LOAD_ADDRESS like this: 1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix 2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE This patch fixes vmlinuz kernel builds on systems where only a 32bit-only math shell is available. Patch Changelog: Version 2 - simplified method by using 'expr' for 'substr' and making it work with dash once again Version 1 - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error of "make clean" - Consider more cases of the VMLINUX_LOAD_ADDRESS Version 0 - initial release Signed-off-by: Alexander Clouter <alex@digriz.org.uk> Acked-by: Wu Zhangjin <wuzhangjin@gmail.com> Patchwork: http://patchwork.linux-mips.org/patch/861/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2010-01-27drm/i915: Selectively enable self-reclaimChris Wilson
Having missed the ENOMEM return via i915_gem_fault(), there are probably other paths that I also missed. By not enabling NORETRY by default these paths can run the shrinker and take memory from the system (but not from our own inactive lists because our shrinker can not run whilst we hold the struct mutex) and this may allow the system to survive a little longer whilst our drivers consume all available memory.
