2011-10-21crypto: talitos - handle descriptor not found in error pathKim Phillips
The CDPR (Current Descriptor Pointer Register) can be unreliable when trying to locate an offending descriptor. Handle that case by (a) not OOPSing, and (b) reverting to the machine internal copy of the descriptor header in order to report the correct execution unit error. Note: printing all execution units' ISRs is not effective because it results in an internal time out (ITO) error and the EU resetting its ISR value (at least when specifying an invalid key length on an SEC 2.2/MPC8313E).

2011-10-21ALSA: hda/realtek - Fix DAC assignments of multiple speakersTakashi Iwai
When a device has multiple speakers and still has the auto-mute support, the driver copies line_outs[] to speaker_outs[]. And then it tries to assign DACs for both. This ended up with the assignment only to the primary DAC to all speakers. This patch fixes the situation by checking the duplicated LO/SPK case appropriately.

2011-10-21perf symbols: Increase symbol KSYM_NAME_LEN sizeRicardo Ribalda Delgado
Fglrx propietary driver has symbol names over 128 chars (:S). This breaks the function kallsyms__parse. This fix increases the size of KSYM_NAME_LEN, so kallsyms__parse can work on such kernels. The only counterparty, is that such function requires 128 more bytes to work.

With per-bus iommu_ops the iommu_found function needs to work on a bus_type too. This patch adds a bus_type parameter to that function and converts all call-places. The function is also renamed to iommu_present because the function now checks if an iommu is present for a given bus and does not check for a global iommu anymore.

2011-10-21crypto: blowfish-x86_64 - improve x86_64 blowfish 4-way performanceJussi Kivilinna
This patch adds improved F-macro for 4-way parallel functions. With new F-macro for 4-way parallel functions, blowfish sees ~15% improvement in speed tests on AMD Phenom II (~5% on Intel Xeon E7330). However when used in 1-way blowfish function new macro would be ~10% slower than original, so old F-macro is kept for 1-way functions. Patch cleans up old F-macro as it is no longer needed in 4-way part. Patch also does register macro renaming to reduce stack usage.

2011-10-21GFS2: rewrite fallocate code to write blocks directlyBenjamin Marzinski
GFS2's fallocate code currently goes through the page cache. Since it's only writing to the end of the file or to holes in it, it doesn't need to, and it was causing issues on low memory environments. This patch pulls in some of Steve's block allocation work, and uses it to simply allocate the blocks for the file, and zero them out at allocation time. It provides a slight performance increase, and it dramatically simplifies the code. Signed-off-by: Benjamin Marzinski <bmarzins@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2011-10-21GFS2: speed up delete/unlink performance for large filesBob Peterson
This patch improves the performance of delete/unlink operations in a GFS2 file system where the files are large by adding a layer of metadata read-ahead for indirect blocks.

2011-10-21GFS2: Fix off-by-one in gfs2_blk2rgrpdSteven Whitehouse
Bob reported: I found an off-by-one problem with how I coded this section: It should be: + else if (blk >= cur->rd_data0 + cur->rd_data) In fact, cur->rd_data0 + cur->rd_data is the start of the next rgrp (the next ri_addr), so without the "=" check it can land on the wrong rgrp. In all normal cases, this won't be a problem: you're searching for a block _within_ the rgrp, which will pass the test properly. Where it gets into trouble is if you search the rgrps for the block exactly equal to ri_addr. I don't think anything in the kernel does this, but I found a place in gfs2-utils gfs2_edit where it does. So I definitely need to fix it in libgfs2. I'd like to suggest we fix it in the kernel as well for the sake of keeping the functions similar. So this patch fixes the above mentioned off by one error as well as removing the unused parent pointer.
