2007-10-10drivers/block/umem: minor cleanupsJeff Garzik
* tab-align DRIVER_*, pci_driver entries * reduced wasted memory by killing unused struct cardinfo members * move free_irq() call above resource unmap, to fix tiny window where irq handler may access recently-unmapped memory * propagate pci_enable_device() return value * use pci_request_regions, pci_release_regions() for resource reservation * call pci_disable_device() in pci_driver::remove() Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-10-10drivers/block/umem: use dev_printk()Jeff Garzik
dev_printk() gives us a consistent prefix (driver name + PCI bus id), which allows us to eliminate the hand-rolled one. Also allows us to eliminate card->card_number, which was used solely in printk() calls. Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-10-10drivers/block/umem: move private include away from include/linuxJeff Garzik
Move include/linux/umem.h to drivers/block, as umem.c is the only user, and its not an exported header. Move the PCI_{VENDOR,DEVICE}_ID_* constants to include/linux/pci_ids.h. Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-10-10Sysace: Move structure allocation from bus binding into common codeGrant Likely

2007-10-10Drop 'size' argument from bio_endio and bi_end_ioNeilBrown
As bi_end_io is only called once when the reqeust is complete, the 'size' argument is now redundant. Remove it. Now there is no need for bio_endio to subtract the size completed from bi_size. So don't do that either. While we are at it, change bi_end_io to return void. Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-10Stop exporting blk_rq_bio_prepNeilBrown
blk_rq_bio_prep is exported for use in exactly one place. That place can benefit from using the new blk_rq_append_bio instead. So - change dm-emc to call blk_rq_append_bio - stop exporting blk_rq_bio_prep, and - initialise rq_disk in blk_rq_bio_prep, as dm-emc needs it.

2007-10-10New function blk_req_append_bioNeilBrown
ll_back_merge_fn is currently exported to SCSI where is it used, together with blk_rq_bio_prep, in exactly the same way these functions are used in __blk_rq_map_user. So move the common code into a new function (blk_rq_append_bio), and don't export ll_back_merge_fn any longer.

2007-10-10Fix various abuse of bio fields in umem.cNeilBrown
umem.c: advances bi_idx and bi_sector to track where it is up to. But it is only ever doing this on one bio, so the updated fields can easily be kept elsewhere (current_*). updates bi_size, but never uses the updated values, so this isn't needed. reuses bi_phys_segments to count how many iovecs have been completely. As the completion happens sequentiually, we can store this information outside the bio too.

2007-10-10Introduce rq_for_each_segment replacing rq_for_each_bioNeilBrown
Every usage of rq_for_each_bio wraps a usage of bio_for_each_segment, so these can be combined into rq_for_each_segment. We define "struct req_iterator" to hold the 'bio' and 'index' that are needed for the double iteration. Signed-off-by: Neil Brown <neilb@suse.de> Various compile fixes by me...

2007-10-09sata_mv: correct S/G table limitsJeff Garzik
The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg().

2007-10-08Correct Makefile rule for generating custom keymapMaarten Bressers
When building a custom keymap, after setting GENERATE_KEYMAP := 1 in drivers/char/Makefile, the kernel build fails like this: CC drivers/char/vt.o make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'. Stop. make[1]: *** [drivers/char] Error 2 make: *** [drivers] Error 2 This was caused by commit af8b128719f5248e542036ea994610a29d0642a6, which deleted a necessary colon from the Makefile rule that generates the keymap, since that rule contains both a target and a target-pattern.

2007-10-07VT_WAITACTIVE: Avoid returning EINTR when not necessaryLinus Torvalds
We should generally prefer to return ERESTARTNOHAND rather than EINTR, so that processes with unhandled signals that get ignored don't return EINTR. This can help with X startup issues: Fatal server error: xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call although the real fix is having the X server always retry EINTR regardless (since EINTR does happen for signals that have handlers installed). Keithp has a patch for that. Regardless, ERESTARTNOHAND is the correct thing to use. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-10-06Fix non-terminated PCI match table in PowerMac IDEBenjamin Herrenschmidt
The PCI device table in the powermac IDE driver isn't properly terminated. Depending on how your kernel is linked and other random factors, you can end up with this driver matched against any other PCI device in your system, possibly crashing at boot. Thanks to Heikki for tracking this down with me, the bug have been there for some time, though it rarely hurts due to luck. In this case, the switch from .22 to .23-rc9 is causing it to show up due to differences in the resulting layout of .data I suppose.

2007-10-01[TCP]: secure_tcp_sequence_number() should not use a too fast clockEric Dumazet
TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock. In order to follow network speed increase, we can use a faster clock, but we should limit this clock so that the delay between two rollovers is greater than MSL (TCP Maximum Segment Lifetime : 2 minutes) Choosing a 64 nsec clock should be OK, since the rollovers occur every 274 seconds.

The new behaviour of CFS exposes a race which occurs if a switch is requested when vt_mode.mode is VT_PROCESS. The process with vc->vt_pid is signaled before vc->vt_newvt is set. This causes the switch to fail when triggered by the monitoing process because the target is still -1.
