Save a byte here and there. Ultimatively useless, but these things always catch my eyes when reading the code so just fix them for now.

2005-07-28[PATCH] x86_64: Icecream has no way of detecting assembler-level includesAndreas Gruenbacher
Icecream preprocesses c sources locally, and sends the result off to a remote host for compiling. It does not recognize includes at assembler level. The fix is to put the assemberincludes an a separate .s file, which will always be assembled locally.

2005-07-28[PATCH] x86_64: cpu hotplug changes kills nmi watchdogAlexander Nyberg
When the x86_64 cpu hotplug changes went in it added a check in default_do_nmi() which kills NMI delivery on any CPU but the BSP. The NMI watchdog is brought up quite some time before the online bit is set in num_online_cpus so this won't work very well. The nmi watchdogs on cpus that are not BSP will never be reprogrammed and no NMIs. Why was this check added? How does an offlined cpu receive an NMI?

2005-07-28[ARM SMP] Ensure secondary CPUs have a clean TLBRussell King
Since ARMv6 CPUs will not flush the TLB on context switches, it is possible that we may end up with some global TLB entries remaining present, eventually upsetting userspace. Explicitly flush the entire TLB on secondary CPUs as they startup, after we have switched to the init_mm page tables. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

can be encoded in the current driver's 4 bit frequency field. This patch updates the driver to support Rev F including 6 bit FIDs and processor ID updates.

2005-07-28powernow-k8 requires that a data structure forDave Jones
each core be created in the _cpu_init function call. The cpufreq infrastructure doesn't call _cpu_init for the second core in each processor. Some systems crashed when _get was called with an odd-numbered core because it tried to dereference a NULL pointer since the data structure had not been created. The attached patch solves the problem by initializing data structures for all shared cores in the _cpu_init function. It should apply to 2.6.12-rc6 and has been tested by AMD and Sun.

2005-07-28[PATCH] Fix incorrect Asus k7m irq router detectionGiancarlo Formicuccia
This patch: http://marc.theaimsgroup.com/?l=bk-commits-head&m=111955644929114&w=2 uncovered a k7m bios bug, where the VT82C686A router is reported as being "586-compatible". The two chips have different pirq mapping, so this leads to "irq routing conflict" on many pci devices. The suggested fix was discussed with Aleksey Gorelov, who helped me to identify the problem as a probable bios bug.

2005-07-27[PATCH] ppc32: 8xx avoid icbi misbehaviour in __flush_dcache_icache_physAnton Wöllert
On 8xx, in the case where a pagefault happens for a process who's not the owner of the vma in question (ptrace for instance), the flush operation is performed via the physical address. Unfortunately, that results in a strange, unexplainable "icbi" instruction fault, most likely due to a CPU bug (see oops below). Avoid that by flushing the page via its kernel virtual address.

2005-07-27[PATCH] s390: external call performanceHeiko Carstens
The kernel uses the SIGP external call order code to signal other CPUs. When running with dedicated CPUs external calls don't get delivered immediately but within a fixed polling invervall. This can lead to delays where the system appears to do nothing. Replace the SIGP external call order with the SIGP emergency call order since this one gets delivered immediately.

2005-07-27[PATCH] s390: spin lock retryMartin Schwidefsky
Split spin lock and r/w lock implementation into a single try which is done inline and an out of line function that repeatedly tries to get the lock before doing the cpu_relax(). Add a system control to set the number of retries before a cpu is yielded. The reason for the spin lock retry is that the diagnose 0x44 that is used to give up the virtual cpu is quite expensive. For spin locks that are held only for a short period of time the costs of the diagnoses outweights the savings for spin locks that are held for a longer timer. The default retry count is 1000.
