* [POWERPC] Consolidate feature fixup codeBenjamin Herrenschmidt2006-10-24
| | | | | | | | | | | | | | | | | There are currently two versions of the functions for applying the feature fixups, one for CPU features and one for firmware features. In addition, they are both in assembly and with separate implementations for 32 and 64 bits. identify_cpu() is also implemented in assembly and separately for 32 and 64 bits. This patch replaces them with a pair of C functions. The call sites are slightly moved on ppc64 as well to be called from C instead of from assembly, though it's a very small change, and thus shouldn't cause any problem.

* [POWERPC] Simplify stolen time calculationStephen Rothwell2006-10-23
| | | | | | | | | | | | | | | | | | In calculating stolen time, we were trying to actually account for time spent in the hypervisor. We don't really have enough information to do that accurately, so don't try. Instead, we now calculate stolen time as time that the current cpu thread is not actually dispatching instructions. On chips without a PURR, we cannot do this, so stolen time will always be zero. On chips with a PURR, this is merely the difference between the elapsed PURR values and the elapsed TB values. This gives us much more sane vaules from tools such as mpstat, even if they are still a bit strange e.g. 2 busy threads on one cpu will both appear to have 50% user time and 50% stolen time while 1 busy thread on a cpu will look like 100% user on one of them and 100% idle on the other.

* | [MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_pageRalf Baechle2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation uses a sequence of a cacheflush and a copy. This is racy in case of a multithreaded debuggee and renders GDB virtually unusable. Aside this fixes a performance hog rendering access to /proc/cmdline very slow and resulting in a enough cache stalls for the 34K AP/SP programming model to make the bare metal code on the non-Linux VPE miss RT deadlines.

| * [PATCH] x86-64: Revert timer routing behaviour back to 2.6.16 stateAndi Kleen2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default route the 8254 over the 8259 and only disable it on ATI boards where this causes double timer interrupts. This should unbreak some Nvidia boards where the timer doesn't seem to tick of it isn't enabled in the 8259. At least one VIA board also seemed to have a little trouble with the disabled 8259. For 2.6.20 we'll try both dynamically without black listing, but I think for .19 this is the safer approach because it has been already well tested in earlier kernels. This also makes the x86-64 behaviour the same as i386. Command line options can change all this of course. Signed-off-by: Andi Kleen <ak@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o A recent change to vmlinux.ld.S file broke kexec as now resulting vmlinux program headers are overlapping in physical address space. o Now all the vsyscall related sections are placed after data and after that mostly init data sections are placed. To avoid physical overlap among phdrs, there are three possible solutions. - Place vsyscall sections also in data phdrs instead of user - move vsyscal sections after init data in bss. - create another phdrs say data.init and move all the sections after vsyscall into this new phdr. o This patch implements the third solution.

| * [PATCH] x86-64: Put more than one cpu in TARGET_CPUSEric W. Biederman2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TARGET_CPUS is the default irq routing poicy. It specifies which cpus the kernel should aim an irq at. In physflat delivery mode we can route an irq to a single cpu. But that doesn't mean our default policy should only be a single cpu is allowed. By allowing the irq routing code to select from multiple cpus this enables systems with more irqs then we can service on a single processor to actually work. I just audited and tested the code and irqbalance doesn't care, and the io_apic.c doesn't care if we have extra cpus in the mask. Everything will use or assume we are using the lowest numbered cpu in the mask if we can't use them all. So this should result in no behavior changes except on systems that need it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks to YH Lu for spotting this. It appears I missed this function when I refactored allocate_irq_vector and introduced irq_domain, with the result that all retriggered irqs would go to cpu 0 even if we were not prepared to receive them there. While reviewing YH's patch I also noticed that this function was missing locking, and since I am now reading two values from two diffrent arrays that looks like a race we might be able to hit in the real world.

| * [PATCH] x86-64: fix page align in e820 allocatorVivek Goyal2006-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently some code pieces assume that address returned by find_e820_area() are page aligned. But looks like find_e820_area() had no such intention and hence one might end up stomping over some of the data. One such case is bootmem allocator initialization code stomped over bss. This patch modified find_e820_area() to return page aligned address. This might be little wasteful of memory but at the same time probably it is easier to handle page aligned memory.

* | [PATCH] Fix potential interrupts during alternative patchingZachary Amsden2006-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | Interrupts must be disabled during alternative instruction patching. On systems with high timer IRQ rates, or when running in an emulator, timing differences can result in random kernel panics because of running partially patched instructions. This doesn't yet fix NMIs, which requires extricating the patch code from the late bug checking and is logically separate (and also less likely to cause problems).
