2007-07-27[SCSI] advansys: lindent and other large, uninteresting changesMatthew Wilcox
- Run Lindent - Move advansys_detect and advansys_release to the end of the file - Split advansys_board_found out of advansys_detect - Rename a few variables, such as shp to shost and pci_devp to pdev - Turn STATIC into static Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-07-27[SCSI] aic79xx, aic7xxx: Fix incorrect width settingJames Bottomley
Wide transfers are required for every setting of PPR apart from QAS. It seems the DV code starts at the minimum, which turns on DT and Wide regardless of the setting of max_width. Redo the PPR and period setting routines to respect max_width (i.e. start at period = 10 if it is zero).

2007-07-27[SCSI] qla2xxx: fix to honor ignored parameters in sysfs attributesSeokmann Ju
This is a patch to fix 'segmentation fault' issue which was initiated by Richard Lary <rlary@us.ibm.com>. Thanks again Richard. - on following sysfs attritute function, changes have made so that both count and offset input parameters are honored by the functions. = qla2x00_sysfs_read_nvram() = qla2x00_sysfs_read_vpd() - made changes so that NVRAM data to be cached to minimize H/W accesses during agent querying of the driver's.

2007-07-27[SCSI] aacraid: draw line in sand, sundry cleanup and version updateSalyzyn, Mark

2007-07-27[SCSI] iscsi_tcp: Turn off bounce buffersMike Christie
It was found by LSI that on setups with large amounts of memory we were bouncing buffers when we did not need to. If the iscsi tcp code touches the data buffer (or a helper does), it will kmap the buffer. iscsi_tcp also does not interact with hardware, so it does not have any hw dma restrictions. This patch sets the bounce buffer settings for our device queue so buffers should not be bounced because of a driver limit.

2007-07-229p: Don't use binary sysctl numbers.Eric W. Biederman
The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that supposedly only moved files also introduced a new 9p sysctl interface that did not properly register it's sysctl binary numbers. And since it was only for debugging clearly did not need a binary fast path in any case. So this patch just remove the binary numbers. See Documentation/sysctl/ctl_unnumbered.txt for more details. While I was at it I cleaned up the sysctl initializers a little as well so there is less to read.

2007-07-22x86: Replace NSC/Cyrix specific chipset access macros by inlined functions.Juergen Beisert
Due to index register access ordering problems, when using macros a line like this fails (and does nothing): setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88); With inlined functions this line will work as expected. Note about a side effect: Seems on Geode GX1 based systems the "suspend on halt power saving feature" was never enabled due to this wrong macro expansion. With inlined functions it will be enabled, but this will stop the TSC when the CPU runs into a HLT instruction. Kernel output something like this: Clocksource tsc unstable (delta = -472746897 ns) This is the 3rd version of this patch. - Adding missed arch/i386/kernel/cpu/mtrr/state.c Thanks to Andres Salomon - Adding some big fat comments into the new header file Suggested by Andi Kleen AK: fixed x86-64 compilation Signed-off-by: Juergen Beisert <juergen@kreuzholzen.de> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
