Fix an oops in the stacktrace code, caused by improper range checking. We subtract 12 off 'fp' before testing to see if it's below the low bound. However, if 'fp' were zero before, it becomes a very large positive number, causing this test to succeed where it should fail. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-05-29[SPARC64]: Eliminate NR_CPUS limitations.David S. Miller
Cheetah systems can have cpuids as large as 1023, although physical systems don't have that many cpus. Only three limitations existed in the kernel preventing arbitrary NR_CPUS values: 1) dcache dirty cpu state stored in page->flags on D-cache aliasing platforms. With some build time calculations and some build-time BUG checks on page->flags layout, this one was easily solved. 2) The cheetah XCALL delivery code could only handle a cpumask with up to 32 cpus set. Some simple looping logic clears that up too. 3) thread_info->cpu was a u8, easily changed to a u16. There are a few spots in the kernel that still put NR_CPUS sized arrays on the kernel stack, but that's not a sparc64 specific problem. Signed-off-by: David S. Miller <davem@davemloft.net>

kmalloc for flush_words resulted in zero size allocation when no k8_northbridges existed. Short circuit the code path for this case. Also remove uneeded zeroing of num_k8_northbridges just after checking if it is zero.

2007-05-23uml: improve PTRACE_SYSEMU checkingJeff Dike
Make the PTRACE_SYSEMU checking more robust. It will make sure that system call numbers are reported correctly. If there is a problem, it will disable PTRACE_SYSEMU use and use PTRACE_SYSCALL instead. Thanks to Balaji G for helping reproduce this problem.

2007-05-23[POWERPC] QE: fix Kconfig 'select' warning with UCC_FASTTimur Tabi
The UCC_GETH Kconfig option in drivers/net/Kconfig had a line to select the UCC_FAST option is arch/powerpc/sysdev/qe_lib/Kconfig, which is only used on PowerPC builds. On other architectures, this would generated a warning. The fix is to have UCC_FAST depend on UCC_GETH.
