When I moved sparc64 over to HZ==1000 this added some problems to the udelay() handling. Specifically, with slower cpus we could now get underflows to zero for things like udelay(1) due to the order of multiplies and shifts. Fix this, and move it out to arch/sparc64/lib/delay.c so it is easier to tinker with this in the future and also to optimize away one of the multiplies for the constant delay case just like other platforms do.

chipsets also, a new X 2D + 3D driver are needed to use this but they have been integrated into at least the X.org tree at this point and I think the XFree86 tree. There are probably a few cleanups necessary for this driver. From: Keith Whitwell <keith@tungstengraphics.com> Signed-off-by:Dave Airlie <airlied@linux.ie>

This optimises the drm code to not do put_user() on memory the kernel allocated and then mmap-installed to userspace, but instead makes it use the kernel virtual address directly instead. From: Arjan van de Ven <arjanv@redhat.com> Signed-off-by:

Here is an HVCS (drivers/char/hvcs.c) patch which fixes the hvcs driver problems with hotplugged vty-server adapters. The current driver handles the adapter index assignment improperly so after a number of device removals and insertions the driver could no longer map a tty->index to a vty-server properly and tty_open() attempts would fail. This patch solves this problem by always assigning the lowest available index to the new adapters and returning an index to the list when the adapter is removed. changelog: drivers/char/hvcs.c =================== -Added hvcs_index_list to manage the lowest available index. -Added four helper functions to manage the list, which include the creation and destruction of the list, the get'ing of the lowest index, and the returning of an index. -Moved free_irq() outside of the hvcs_final_close() function in order to get it out of the spinlock. -Rearranged hvcs_close() to accomodate the previous change. -Removed local CLC_LENGTH define and used HVCS_CLC_LENGTH from arch/ppc64/hvcserver.h instead. -Cleaned up some printks and did some house keeping on the changelog. Documentation/powerpc/hvcs.txt ============================== -Added information on sysfs 'index' attribute added in previous hvcs patch. -Added Q & A section on how to find the proper dev node for a newly added adapter. I think this is the last of the HVCS patches for a while, as all of my oustanding issues have been dealt with. Signed-off-by:

There is a minor problem in function start_kernel. start_kernel will enable interrupt after calling profile_init. However, before that, function time_init on IA64 platform could enable interrupt. See this call sequence: start_kernel ->time_init ->ia64_init_itm ->register_time_interpolator ->write_seqlock_irq. Signed-off-by:Zhang Yanmin <yanmin.zhang@intel.com> Signed-off-by:

We have this patch that adds ftape support for x86_64 and cleans up the alpha support a little. The comments look like Vojtech did the x86_64 part and I guess the alpha bits are from Herbert Xu. Signed-off-by:

While trying out compiling of reiser4 on sparc64, ppc64, alpha, and ia64, I discovered that WAITQUEUE_DEBUG is nowhere defined in 2.6.x, and various compiler versions spew copious warnings at #if on it. Convert __SEMAPHORE_INITIALIZER() to C99 initializers while in the area. Signed-off-by:

32 bit compatibility code sometimes needs to copy unaligned data across kernel/user boundary and currently there is no architecture independent API to do it. (1) Introduce new APIs __{get,put}_user_unaligned. These APIs are necessary because the optimal way to copy unaligned data across kernel/user boundary is different on different architectures. Some architectures don't even care about alignment. On some __put_user is faster than __copy_to_user for small sizes. (2) Optimize __{get,put}_user_unaligned for ia64, x86-64, s390, ppc64. (3) Fix compat_filldir64() which is broken on big-endian machines Thanks to Arnd Bergmann <arnd@arndb.de> for his help. Signed-off-by:Gordon Jin <gordon.jin@intel.com> Signed-off-by:

It seems a little unsafe to me to have oom killer badness points of type int, when all the underlying objects are unsigned long. I can't immediately think of a case where this matters much, but e.g. a long-running job or daemon on a 64 bit machine might lose it's bonus because of that. Signed-off-by:

Add support for netmos devices to the parallel port driver. NetMOS 9805 support is already in the kernel, this patch adds the support for the missing 9735,9855,9755 and 9715 chips. And another remark: The 9735 and 9835 seem to be chips with serial *and* parallel interfaces, so I suppose they are already claimed somewhere in the serial driver. I don't know whether this causes any problems. I'm sorry that I can't test, I've only a 9805 here. Any idea how these "dual" chips have to be handled by the kernel? Signed-off-by:

Unaccount VM_DONTCOPY vmas properly; the child inherits the whole of the parent's virtual accounting from the memcpy() in copy_mm(), but the VM_DONTCOPY check here is where a decision is made for the child not to inherit the vmas corresponding to some accounted memory usages. Hence, unaccount them when skipping over them here. Signed-off-by:
