2010-03-06checkpatch: trivial fix for trailing statements checkHidetoshi Seto
In case if the statement and the conditional are in one line, the line appears in the report doubly. And items of this check have no blank line before the next item. This patch fixes these trivial problems, to improve readability of the report.

2010-03-06mmc: at91_mci: enable large data blocksWolfgang Muees
This patch is setting some max_ variables for the IO elevator, so the elevator will put requests for large data blocks to the driver. This is critical for a) speed and b) wear leveling of the flash chip controller: Otherwise the controller will treat the SD card badly with millions of single 4 KByte write commands. This will lead to a shorter life time for the SD cards.

2010-03-06s3cmci: initialize default platform data no_wprotect and no_detect with 1Lars-Peter Clausen
If no platform_data was givin to the device it's going to use it's default platform data struct which has all fields initialized to zero. As a result the driver is going to try to request gpio0 both as write protect and card detect pin. Which of course will fail and makes the driver unusable Previously to the introduction of no_wprotect and no_detect the behavior was to assume that if no platform data was given there is no write protect or card detect pin. This patch restores that behavior.

2010-03-06sdio: introduce API for special power management featuresNicolas Pitre
This patch series provides the core changes needed to allow SDIO cards to remain powered and active while the host system is suspended, and let them wake up the host system when needed. This is used to implement wake-on-lan with SDIO wireless cards at the moment. Patches to add that support to the libertas driver will be posted separately. This patch: Some SDIO cards have the ability to keep on running autonomously when the host system is suspended, and wake it up when needed. This however requires that the host controller preserve power to the card, and configure itself appropriately for wake-up. There is however 4 layers of abstractions involved: the host controller driver, the MMC core code, the SDIO card management code, and the actual SDIO function driver. To make things simple and manageable, host drivers must advertise their PM capabilities with a feature bitmask, then function drivers can query and set those features from their suspend method. Then each layer in the suspend call chain is expected to act upon those bits accordingly.

2010-03-06sdhci: improve sdhci sdhci_set_adma_desc() codeBen Dooks
sdhci_set_adma_desc() is using byte-writes to write data in a specified order into memory. Change to using __le16 for the two byte and __le32 for the four byte cases and use the cpu_to_{le16,le32} to do the conversion before writing. This will reduce the size of the code and the number of writes as we no longer need to chop the data up before writing. As an example on ARM S3C64XX SoC, in little-endian configuration: 000000d4 <sdhci_set_adma_desc>: - d8: e1a0c423 lsr ip, r3, #8 - dc: e1a0ec21 lsr lr, r1, #24 - e0: e1a04821 lsr r4, r1, #16 - e4: e1a05421 lsr r5, r1, #8 - e8: e1a06442 asr r6, r2, #8 - ec: e5c0c001 strb ip, [r0, #1] - f0: e5c0e007 strb lr, [r0, #7] - f4: e5c04006 strb r4, [r0, #6] - f8: e5c05005 strb r5, [r0, #5] - fc: e5c01004 strb r1, [r0, #4] - 100: e5c06003 strb r6, [r0, #3] - 104: e5c02002 strb r2, [r0, #2] - 108: e5c03000 strb r3, [r0] + d4: e5801004 str r1, [r0, #4] + d8: e1c030b0 strh r3, [r0] + dc: e1c020b2 strh r2, [r0, #2] Signed-off-by: Ben Dooks <ben-linux@fluff.org> Cc: Pierre Ossman <pierre@ossman.eu> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-03-06ricoh_mmc: port from driver to pci quirkMaxim Levitsky
This patch solves nasty problem original driver has. Original goal of the ricoh_mmc was to disable this device because then, mmc cards can be read using standard SDHCI controller, thus avoiding writing of yet another driver. However, the act of disablement, makes other pci functions that belong to this controller (xD and memstick) shift up one level, thus pci core has now wrong idea about these devices. To fix this issue, this patch moves the driver into the pci quirk section, thus it is executes before the pci is enumerated, and therefore solving that issue, also same sequence of commands is performed on resume for same reasons. Also regardless of the above, this way is cleaner.

2010-03-06lib: more scalable list_sort()Don Mullis
XFS and UBIFS can pass long lists to list_sort(); this alternative implementation scales better, reaching ~3x performance gain when list length exceeds the L2 cache size. Stand-alone program timings were run on a Core 2 duo L1=32KB L2=4MB, gcc-4.4, with flags extracted from an Ubuntu kernel build. Object size is 581 bytes compared to 455 for Mark J. Roberts' code. Worst case for either implementation is a list length just over a power of two, and to roughly the same degree, so here are timing results for a range of 2^N+1 lengths. List elements were 16 bytes each including malloc overhead; initial order was random. time (msec) Tatham-Roberts | generic-Mullis-v2 loop_count length | | ratio 4000000 2 206 294 1.427 2000000 3 176 227 1.289 1000000 5 199 172 0.864 500000 9 235 178 0.757 250000 17 243 182 0.748 125000 33 261 196 0.750 62500 65 277 209 0.754 31250 129 292 219 0.75 15625 257 317 235 0.741 7812 513 340 252 0.741 3906 1025 362 267 0.737 1953 2049 388 283 0.729 ~ L1 size 976 4097 556 323 0.580 488 8193 678 361 0.532 244 16385 773 395 0.510 122 32769 844 418 0.495 61 65537 917 454 0.495 30 131073 1128 543 0.481 15 262145 2355 869 0.369 ~ L2 size 7 524289 5597 1714 0.306 3 1048577 6218 2022 0.325 Mark's code does not actually implement the usual or generic mergesort, but rather a variant from Simon Tatham described here: http://www.chiark.greenend.org.uk/~sgtatham/algorithms/listsort.html Simon's algorithm performs O(log N) passes over the entire input list, doing merges of sublists that double in size on each pass. The generic algorithm instead merges pairs of equal length lists as early as possible, in recursive order. For either algorithm, the elements that extend the list beyond power-of-two length are a special case, handled as nearly as possible as a "rounding-up" to a full POT. Some intuition for the locality of reference implications of merge order may be gotten by watching this animation: http://www.sorting-algorithms.com/merge-sort Simon's algorithm requires only O(1) extra space rather than the generic algorithm's O(log N), but in my non-recursive implementation the actual O(log N) data is merely a vector of ~20 pointers, which I've put on the stack. Long-running list_sort() calls: If the list passed in may be long, or the client's cmp() callback function is slow, the client's cmp() may periodically invoke cond_resched() to voluntarily yield the CPU. All inner loops of list_sort() call back to cmp(). Stability of the sort: distinct elements that compare equal emerge from the sort in the same order as with Mark's code, for simple test cases. A boot-time test is provided to verify this and other correctness requirements. A kernel that uses drm.ko appears to run normally with this change; I have no suitable hardware to similarly test the use by UBIFS.

2010-03-06scripts/get_maintainer.pl: fix possible infinite loopJoe Perches
If MAINTAINERS section entries are misformatted, it was possible to have an infinite loop. Correct the defect by always moving the index to the end of section + 1 Also, exit check for exclude as soon as possible.

perlcritic is a standard checker for Perl Best Practices. This patch fixes most of the warnings in the get_maintainer script.

2010-03-06scripts/get_maintainer.pl: add --file-emails, find embedded email addressesJoe Perches
Add an imperfect option to search a source file for email addresses. New option: --file-emails or --fe email addresses in files are freeform text and are nearly impossible to parse. Still, might as well try to do a somewhat acceptable job of finding them. This code should find all addresses that are in the form addr@domain.tld The code assumes that up to 3 alphabetic words along with dashes, commas, and periods that preceed the email address are a name. If 3 words are found for the name, and one of the first two words are a single letter and period, or just a single letter then the 3 words are use as name otherwise the last 2 words are used. Some variants that are shown correctly: John Smith <jksmith@domain.org> Random J. Developer <rjd@tld.com> Random J. Developer (rjd@tld.com) J. Random Developer rjd@tld.com Variants that are shown nominally correctly: Written by First Last (funny-addr@somecompany.com) is shown as: First Last <funny-addr@somecompany.com> Variants that are shown incorrectly: Some Really Long Name <srln@foo.bar> MontaVista Software, Inc. <source@mvista.com> are returned as: Long Name <srln@foo.bar> "Software, Inc" <source@mvista.com> --roles and --rolestats show "(in file)" for matches. For instance: Without -file-emails: $ ./scripts/get_maintainer.pl -f -nogit -roles net/core/netpoll.c David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL]) linux-kernel@vger.kernel.org (open list) With -fe: $ ./scripts/get_maintainer.pl -f -fe -nogit -roles net/core/netpoll.c David S. Miller <davem@davemloft.net> (maintainer:NETWORKING [GENERAL]) Matt Mackall <mpm@selenic.com> (in file) Ingo Molnar <mingo@redhat.com> (in file) linux-kernel@vger.kernel.org (open list) netdev@vger.kernel.org (open list:NETWORKING [GENERAL]) The number of email addresses in the file in not limited. Neither is the number of returned email addresses.
