2005-09-12[PATCH] USB: add apple usb touchpad driverStelian Pop
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. Credits go to Johannes Berg for reverse-engineering the touchpad protocol, Frank Arnold for further improvements, and Alex Harper for some additional information about the inner workings of the touchpad sensors.

2005-09-12[PATCH] USB: sisusb[vga] updateThomas Winischhofer
here is a new and extended version of the sisusbvga (previously: sisusb) driver. The patch is against 2.6.13 and updates the driver to version 0.0.8. 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. Heavily tested, as usual. Please apply. 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 respective core changes before or after 2.6.14.

2005-09-12[PATCH] i386: add memory clobbers to syscall macrosAndi Kleen
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. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Increase TLB flush array sizeAndi Kleen
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. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-09-12[PATCH] x86-64: Make remote TLB flush more scalableAndi Kleen
Instead of using a global spinlock to protect the state of the remote TLB flush use a lock and state for each sending CPU. To tell the receiver where to look for the state use 8 different call vectors. Each CPU uses a specific vector to trigger flushes on other CPUs. Depending on the received vector the target CPUs look into the right per cpu variable for the flush data. When the system has more than 8 CPUs they are hashed to the 8 available vectors. The limited global vector space forces us to this right now. In future when interrupts are split into per CPU domains this could be fixed, at the cost of needing more IPIs in flat mode. Also some minor cleanup in the smp flush code and remove some outdated debug code. Requires patch to move cpu_possible_map setup earlier.
