One change may improve some S1 or S3 resume cases, and the other
seems mostly to explain some strange state "lsusb" would show.
Two fixes:

  - On resume, don't think about resuming any unpowered port, or
    resetting any port with OWNER set to the OHCI/UHCI companion.
    This will make some S1 and S3 resume scenarios work better.

  - PORT_CSC was not being cleared correctly in ehci_hub_status_data.
    This was visible at least through current versions of "lsusb",
    and might have caused some other hub related strangeness.

    The fix addresses all three write-to-clear bits, using the same
    approach that UHCI happens to use:  a mask of bits that are
    cleared in most writes to that port status register.

[PATCH] USB: add apple usb touchpad driver

This is a driver for the USB touchpad which can be found on post-February 2005
Apple PowerBooks.

This driver is derived from Johannes Berg's appletrackpad driver [1],
but it has been improved in some areas:
    * appletouch is a full kernel driver, no userspace program is necessary
    * appletouch can be interfaced with the synaptics X11 driver[2], in order
      to have touchpad acceleration, scrolling, two/three finger tap, etc.

This driver has been tested by the readers of the 'debian-powerpc' mailing
list for a few weeks now and I believe it is now ready for inclusion into the
mainline kernel.

Frank Arnold for further improvements, and Alex Harper for some additional

Additions include complete VGA/EGA text console support and a build-in
display mode infrastructure for userland applications that don't know
 about the graphics internals.

Fixes include some BE/LE issues and a get/put_dev bug in the previous
version.

Other changes include a change of the module name from "sisusb" to
"sisusbvga". The previous one was too generic IMHO.

Please note that the patch also affects the Makefile in
drivers/video/console as the driver requires the VGA 8x16 font in case
the text console part is selected.

One thing though: I already prepared for removal of the "mode" field and
the changed "name" field in the usb_class_driver structure. This will
perhaps need some refinement depending on whether you/Linus merge the

Andi Kleen [Mon, 12 Sep 2005 16:49:24 +0000 (18:49 +0200)]
[PATCH] i386: add memory clobbers to syscall macros

As noted by matz@suse.de

The problem is, that on i386 the syscallN
macro is defined like so:

  long __res; \
  __asm__ volatile ("int $0x80" \
        : "=a" (__res) \
        : "0" (__NR_##name),"b" ((long)(arg1)),"c" ((long)(arg2)), \
          "d" ((long)(arg3)),"S" ((long)(arg4)),"D" ((long)(arg5))); \

If one of the arguments (in the _llseek syscall it's the arg4) is a pointer
which the syscall is expected to write to (to the memory pointed to by this
ptr), then this side-effect is not captured in the asm.

If anyone uses this macro to define it's own version of the syscall
(sometimes necessary when not using glibc) and it's inlined, then GCC
doesn't know that this asm write to "*dest", when called like so for instance:

  out = 1;
  llseek (fd, bla, blubb, &out, trara)
  use (out);

Here nobody tells GCC that "out" actually is written to (just a pointer to it
is passed to the asm).  Hence GCC might (and in the above bug did)
copy-propagate "1" into the second use of "out".

The easiest solution would be to add a "memory" clobber to the definition
of this syscall macro.  As this is a syscall, it shouldn't inhibit too many
optimizations.

[PATCH] x86-64: Increase TLB flush array size

The generic TLB flush functions kept upto 506 pages per
CPU to avoid too frequent IPIs.

This value was done for the L1 cache of older x86 CPUs,
but with modern CPUs it does not make much sense anymore.
TLB flushing is slow enough that using the L2 cache is fine.

This patch increases the flush array on x86-64 to cache
5350 pages. That is roughly 20MB with 4K pages. It speeds
up large munmaps in multithreaded processes on SMP considerably.

The cost is roughly 42k of memory per CPU, which is reasonable.

I only increased it on x86-64 for now, but it would probably
make sense to increase it everywhere. Embedded architectures
with SMP may keep it smaller to save some memory per CPU.
