Jeff Garzik baf14aa14e sata_mv: correct S/G table limits
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().

Maarten Bressers e2a57a8159 Correct Makefile rule for generating custom keymap
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 af8b128719, which
deleted a necessary colon from the Makefile rule that generates the keymap,
since that rule contains both a target and a target-pattern.  The following
patch puts the colon back:

Linus Torvalds 70cb97935b VT_WAITACTIVE: Avoid returning EINTR when not necessary
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.

Benjamin Herrenschmidt 71e4eda8ce Fix non-terminated PCI match table in PowerMac IDE
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.

Eric Dumazet 9b42c336d0 [TCP]: secure_tcp_sequence_number() should not use a too fast clock
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.

Benjamin Herrenschmidt 1bef7dc00c Fix bogus PCI quirk for e100
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.

Linus Torvalds 5309809129 Add explicit zeroing to "envp" array in device 'show' method
As Stephen Hemminger says, this is a "belt and suspenders" patch that
zeroes the envp array at allocation time, even though all the users
should NULL-terminate it anyway (and we've hopefully fixed everybody
that doesn't do that).

And we'll apparently clean the whole envp thing up for 2.6.24 anyway.

But let's just be robust, and do both this *and* make sure that all
users are doing the right thing.
