There was one small but very significant change in the previous patch:
mprotect's flush_tlb_range fell outside the page_table_lock: as it is in 2.4,
but that doesn't prove it safe in 2.6.
On some architectures flush_tlb_range comes to the same as flush_tlb_mm, which
has always been called from outside page_table_lock in dup_mmap, and is so
proved safe. Others required a deeper audit: I could find no reliance on
page_table_lock in any; but in ia64 and parisc found some code which looks a
bit as if it might want preemption disabled. That won't do any actual harm,
so pending a decision from the maintainers, disable preemption there.
Remove comments on page_table_lock from flush_tlb_mm, flush_tlb_range and
flush_tlb_page entries in cachetlb.txt: they were rather misleading (what
generic code does is different from what usually happens), the rules are now
changing, and it's not yet clear where we'll end up (will the generic
tlb_flush_mmu happen always under lock? never under lock? or sometimes under
and sometimes not?).

Please, please now delete the Atari CONFIG_STRAM_SWAP code. It may be
excellent and ingenious code, but its reference to swap_vfsmnt betrays that it
hasn't been built since 2.5.1 (four years old come December), it's delving
deep into matters which are the preserve of core mm code, its only purpose is
to give the more conscientious mm guys an anxiety attack from time to time;
yet we keep on breaking it more and more.
If you want to use RAM for swap, then if the MTD driver does not already
provide just what you need, I'm sure David could be persuaded to add the
extra. But you'd also like to be able to allocate extents of that swap for
other use: we can give you a core interface for that if you need. But unbuilt
for four years suggests to me that there's no need at all.
I cannot swear the patch below won't break your build, but believe so.

This revised patch (as586b) makes usb-handoff permanently true and no
longer a kernel boot parameter. It also removes the piix3_usb quirk code;
that was nothing more than an early version of the USB handoff code
(written at a time when Intel's PIIX3 was about the only motherboard with
USB support). And it adds identifiers for the three PCI USB controller
classes to pci_ids.h.

Add PEC support to the lm90 driver. Only the ADM1032 chip supports it,
and in a rather tricky way, which is why this patch comes with
documentation reinforcements. At least, this demonstrates that the new
PEC support logic in i2c-core can properly deal with chips with partial
PEC support.
As enabling PEC causes a significant performance drop, it can be
disabled through a sysfs file (unsurprisingly named "pec").

Drop legacy ISA address support from the it87 driver. All supported
chips are Super-I/O chips, so the device ISA address can be safely read
from Super-I/O space rather than blindly assumed.
Two nearby inaccurate documentation statements have been fixed as well:
* The IT8705F doesn't have an SMBus interface.
* The SiS950 doesn't have a distinct prefix.

Implement the I2C block transactions on VIA chips which support them:
VT82C686B, VT8233, VT8233A, VT8235 and VT8237R. This speeds up EEPROM
accesses by a factor 10 or so.

and Andreas Henriksson for their help in testing this new feature.
