2010-03-01Debugging options for the DMA engine subsystemLinus Walleij
This adds Kconfig options for DEBUG and VERBOSE_DEBUG to the DMA engine subsystem, I got tired of editing the Makefile manually each time I want to debug things in here, modelled this on the debug switches for other subsystems and works like a charm when working on our DMA engines.

2010-02-28iop-adma: redundant/wrong tests in iop_*_count()?Roel Kluin
When we reach the loop, len is at least 1, we only stay in the loop when len is at least MAX_BYTE_COUNT + 1, MAX_BYTE_COUNT is subtracted in each iteration. So when we leave the loop, or didn't take it, len is at least 1. Testing whether len is non-zero appears redundant.

2010-02-28dmatest: fix handling of an even number of xor_sourcesDan Williams

2010-02-28dmatest: correct raid6 PQ testAnatolij Gustschin
The number of PQ sources specified by module parameter "pq_sources" is always forced odd to fit into dmatest's destination verificaton scheme. But number of PQ sources and coefficients as passed to the driver's prep_dma_pq() is not adjusted accordingly. Fix it now to get correct PQ testing results in the case passed "pq_sources" parameter is even.

2010-02-02fsldma: major cleanups and fixesIra Snyder
Fix locking. Use two queues in the driver, one for pending transacions, and one for transactions which are actually running on the hardware. Call dma_run_dependencies() on descriptor cleanup so that the async_tx API works correctly. There are a number of places throughout the code where lists of descriptors are freed in a loop.

2010-02-02fsldma: simplify IRQ probing and handlingIra Snyder
The IRQ probing is needlessly complex. All off the 83xx device trees in arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the controller, and one for each channel. These interrupts are all attached to the same IRQ line. This causes an interesting situation if two channels interrupt at the same time. The per-controller handler will handle the first channel, and the per-channel handler will handle the remaining channels. Instead of this mess, we fix the bug in the per-controller handler, and make it handle all channels that generated an interrupt. When a per-controller handler is specified in the device tree, we prefer to use the shared handler instead of the per-channel handler. The 85xx/86xx controllers do not have a per-controller interrupt, and instead use a per-channel interrupt. This behavior has not been changed. Signed-off-by: Ira W.

2010-01-29mm: fix migratetype bug which slowed swappingHugh Dickins
After memory pressure has forced it to dip into the reserves, 2.6.32's 5f8dcc21211a3d4e3a7a5ca366b469fb88117f61 "page-allocator: split per-cpu list into one-list-per-migrate-type" has been returning MIGRATE_RESERVE pages to the MIGRATE_MOVABLE free_list: in some sense depleting reserves. Fix that in the most straightforward way (which, considering the overheads of alternative approaches, is Mel's preference): the right migratetype is already in page_private(page), but free_pcppages_bulk() wasn't using it. How did this bug show up? As a 20% slowdown in my tmpfs loop kbuild swapping tests, on PowerMac G5 with SLUB allocator. Bisecting to that commit was easy, but explaining the magnitude of the slowdown not easy. The same effect appears, but much less markedly, with SLAB, and even less markedly on other machines (the PowerMac divides into fewer zones than x86, I think that may be a factor). We guess that lumpy reclaim of short-lived high-order pages is implicated in some way, and probably this bug has been tickling a poor decision somewhere in page reclaim. But instrumentation hasn't told me much, I've run out of time and imagination to determine exactly what's going on, and shouldn't hold up the fix any longer: it's valid, and might even fix other misbehaviours.

2010-01-29Split 'flush_old_exec' into two functionsLinus Torvalds
'flush_old_exec()' is the point of no return when doing an execve(), and it is pretty badly misnamed. It doesn't just flush the old executable environment, it also starts up the new one. Which is very inconvenient for things like setting up the new personality, because we want the new personality to affect the starting of the new environment, but at the same time we do _not_ want the new personality to take effect if flushing the old one fails. As a result, the x86-64 '32-bit' personality is actually done using this insane "I'm going to change the ABI, but I haven't done it yet" bit (TIF_ABI_PENDING), with SET_PERSONALITY() not actually setting the personality, but just the "pending" bit, so that "flush_thread()" can do the actual personality magic. This patch in no way changes any of that insanity, but it does split the 'flush_old_exec()' function up into a preparatory part that can fail (still called flush_old_exec()), and a new part that will actually set up the new exec environment (setup_new_exec()). All callers are changed to trivially comply with the new world order. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

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

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: 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.

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.

2010-01-28MIPS: Fix vmlinuz build for 32bit-only math shellsAlexander Clouter
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.
