2007-10-11mmc: don't use weight32()Nicolas Pitre
Using weight32() to determine if a value is a power of 2 is a rather heavi weight solution. The classic idiom is (x & (x - 1)) == 0, but the kernel already provide a is_power_of_2 function for it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-10-10pxamci: support arbitrary block sizeNicolas Pitre
The PXA has two transmit FIFOes, each32 byte deep. when one FIFO is full and the other one has been transmitted, they are automatically swapped and DMA is triggered for another 32 byte burst. However, when there is less than 32 bytes left to send, the FIFO swap has to be done manually. This is required for some SDIO transfers which are not required to be multiples of 32 bytes. A DMA completion interrupt is set for each descriptor which length isn't a multiple of 32 in order to force the FIFO swap. While at it, the DMA interrupt handler has been made a bit more resilient against errors. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
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.

2007-10-06sdio: make the IRQ thread more resilient in the presence of bad statesNicolas Pitre
Currently we print a message about some bad states wrt function IRQ handlers but return 0 from process_sdio_pending_irqs() nevertheless. This can lead to an infinite loop as nothing might have cleared the condition for the pending card interrupt from the host controller by the time host->ops->enable_sdio_irq(host, 1) is called.

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.

2007-09-28Fix bogus PCI quirk for e100Benjamin Herrenschmidt
Linas reported me that some machines were crashing at boot in quirk_e100_interrupt. It appears that this quirk is doing an ioremap directly on a PCI BAR value, which isn't legal and will cause all sorts of bad things to happen on architectures where PCI BARs don't directly match processor bus addresses. This fixes it by using the proper PCI resources instead which is possible since the quirk has been moved by a previous commit to happen late enough for that.
