Writing even a disabled value seems to mess up some matrox graphics cards. It may be a card-related issue, but we may also be writing reserved low bits in the result. This was a fall-out of switching x86 over to the generic PCI resource allocation code, and needs more debugging. In particular, the old x86 code defaulted to not doing any resource allocations at all for ROM resources. In the meantime, this has been reported to make X happier by Helge Hafting <helgehaf@aitel.hist.no>. Signed-off-by:Linus Torvalds <torvalds@osdl.org>

It may seem small, but most cards need much less, if any, and this not only makes the code adhere to the comment, it seems to fix a boot-time lockup on a ThinkPad 380XD laptop reported by Tero Roponen <teanropo@cc.jyu.fi> Signed-off-by:

One critical fix and two minor fixes for 2.6.13-rc7: - Max depth must currently be 2 to allow barriers to function on SCSI - Prefer sync request over async in choosing the next request - Never allow async request to preempt or disturb the "anticipation" for a single cfq process context. This is as-designed, the code right now is buggy in that area. Signed-off-by:

pcibios_bus_to_resource is exported on all architectures except ia64 and sparc. Add exports for the two missing architectures. Needed when Yenta socket support is compiled as a module. Signed-off-by:

I mistakedly disabled fusion support in an earlier update. Fusion is commonly used on many x86-64 systems, so this was a problem. This patch fixes that. Signed-off-by:

This patch puts back the export of machine_power_off() that was removed by some janitor as it's used for emergency shutdown by the G5 thermal control driver. Wether that driver should use kernel_power_off() instead is debatable and a post-2.6.13 decision. In the meantime, please commit that patch that fixes the driver for now. Signed-off-by:

As reported by Paul Mackerras <paulus@samba.org>, the previous patch "cpu_exclusive sched domains fix" broke the ppc64 build with CONFIC_CPUSET, yielding error messages: kernel/cpuset.c: In function 'update_cpu_domains': kernel/cpuset.c:648: error: invalid lvalue in unary '&' kernel/cpuset.c:648: error: invalid lvalue in unary '&' On some arch's, the node_to_cpumask() is a function, returning a cpumask_t. But the for_each_cpu_mask() requires an lvalue mask. The following patch fixes this build failure by making a copy of the cpumask_t on the stack. Signed-off-by:

As pointed out in the following thread, the CLOCK_TICK_RATE setting for IXP4xx is incorrect b/c the HW ignores the lowest 2 bits of the LATCH value. http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-August/030950.html Tnx to George Anziger and Egil Hjelmeland for finding the issue.

This keeps the kernel/cpuset.c routine update_cpu_domains() from invoking the sched.c routine partition_sched_domains() if the cpuset in question doesn't fall on node boundaries. I have boot tested this on an SN2, and with the help of a couple of ad hoc printk's, determined that it does indeed avoid calling the partition_sched_domains() routine on partial nodes. I did not directly verify that this avoids setting up bogus sched domains or avoids the oops that Hawkes saw. This patch imposes a silent artificial constraint on which cpusets can be used to define dynamic sched domains. This patch should allow proceeding with this new feature in 2.6.13 for the configurations in which it is useful (node alligned sched domains) while avoiding trying to setup sched domains in the less useful cases that can cause the kernel corruption and oops.

The code to detect IO links on Opteron would not check if the node had actually memory. This could lead to pci_bus_to_node returning an invalid node, which might cause crashes later when dma_alloc_coherent passes it to page_alloc_node(). The bug has been there forever but for some reason it is causing now crashes. Signed-off-by:

i386 floating-point exception handling has a bug that can cause error code 0 to be sent instead of the proper code during signal delivery. This is caused by unconditionally checking the IS and c1 bits from the FPU status word when they are not always relevant. The IS bit tells whether an exception is a stack fault and is only relevant when the exception is IE (invalid operation.) The C1 bit determines whether a stack fault is overflow or underflow and is only relevant when IS and IE are set. Signed-off-by:

either icu_data declaration for SMP case should be taken out of m32102.h, or its declarations for m32700ut and opsput should not be static for SMP. Patch does the latter - judging by comments in m32102.h it is intended to be non-static. Signed-off-by:
