2008-04-29Taint kernel after WARN_ON(condition)Nur Hussein
The kernel is sent to tainted within the warn_on_slowpath() function, and whenever a warning occurs the new taint flag 'W' is set. This is useful to know if a warning occurred before a BUG by preserving the warning as a flag in the taint state. This does not work on architectures where WARN_ON has its own definition. These archs are: 1. s390 2. superh 3. avr32 4. parisc The maintainers of these architectures have been added in the Cc: list in this email to alert them to the situation. The documentation in oops-tracing.txt has been updated to include the new flag.

2008-04-29Avoid divides in BITS_TO_LONGSEric Dumazet
BITS_PER_LONG is a signed value (32 or 64) DIV_ROUND_UP(nr, BITS_PER_LONG) performs signed arithmetic if "nr" is signed too. Converting BITS_TO_LONGS(nr) to DIV_ROUND_UP(nr, BITS_PER_BYTE * sizeof(long)) makes sure compiler can perform a right shift, even if "nr" is a signed value, instead of an expensive integer divide. Applying this patch saves 141 bytes on x86 when CONFIG_CC_OPTIMIZE_FOR_SIZE=y and speedup bitmap operations.

2008-04-29mm: fix misleading __GFP_REPEAT related commentsNishanth Aravamudan
The definition and use of __GFP_REPEAT, __GFP_NOFAIL and __GFP_NORETRY in the core VM have somewhat differing comments as to their actual semantics. Annoyingly, the flags definition has inline and header comments, which might be interpreted as not being equivalent. Just add references to the header comments in the inline ones so they don't go out of sync in the future. In their use in __alloc_pages() clarify that the current implementation treats low-order allocations and __GFP_REPEAT allocations as distinct cases. To clarify, the flags' semantics are: __GFP_NORETRY means try no harder than one run through __alloc_pages __GFP_REPEAT means __GFP_NOFAIL __GFP_NOFAIL means repeat forever order <= PAGE_ALLOC_COSTLY_ORDER means __GFP_NOFAIL Signed-off-by: Nishanth Aravamudan <nacc@us.ibm.com> Acked-by: Mel Gorman <mel@csn.ul.ie> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-04-29block: Skip I/O merges when disabledAlan D. Brunelle
The block I/O + elevator + I/O scheduler code spend a lot of time trying to merge I/Os -- rightfully so under "normal" circumstances. However, if one were to know that the incoming I/O stream was /very/ random in nature, the cycles are wasted. This patch adds a per-request_queue tunable that (when set) disables merge attempts (beyond the simple one-hit cache check), thus freeing up a non-trivial amount of CPU cycles. Signed-off-by: Alan D.

2008-04-29block: add large command supportFUJITA Tomonori
This patch changes rq->cmd from the static array to a pointer to support large commands. We rarely handle large commands. So for optimization, a struct request still has a static array for a command. rq_init sets rq->cmd pointer to the static array.

2008-04-29block: rename and export rq_init()FUJITA Tomonori
This rename rq_init() blk_rq_init() and export it. Any path that hands the request to the block layer needs to call it to initialize the request. This is a preparation for large command support, which needs to initialize the request in a proper way (that is, just doing a memset() will not work).

2008-04-29[RAPIDIO] Add RapidIO multi mport supportZhang Wei
The original RapidIO driver suppose there is only one mpc85xx RIO controller in system. So, some data structures are defined as mpc85xx_rio global, such as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's private members. And you can define multi RIO OF-nodes in dts file for multi RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in Freescale's silicon. And the mport operation function declaration should be changed to know which RapidIO controller is target.

2008-04-29block: add dma alignment and padding support to blk_rq_map_kernFUJITA Tomonori
This patch adds bio_copy_kern similar to bio_copy_user. blk_rq_map_kern uses bio_copy_kern instead of bio_map_kern if necessary. bio_copy_kern uses temporary pages and the bi_end_io callback frees these pages. bio_copy_kern saves the original kernel buffer at bio->bi_private it doesn't use something like struct bio_map_data to store the information about the caller.

It's possible that there are out-of-tree drivers that use these interfaces. They should be changed to either (1) use PNP quirks to work around broken hardware or firmware, or (2) use the sysfs interfaces to control resource usage from userspace.

Add pnp_init_resources(struct pnp_dev *) to replace pnp_init_resource_table(), which takes a pointer to the pnp_resource_table itself. Passing only the pnp_dev * reduces the possibility for error in the caller and removes the pnp_resource_table implementation detail from the interface. Even though pnp_init_resource_table() is exported, I did not export pnp_init_resources() because it is used only by the PNP core.
