2009-09-20x86: Increase timeout for EHCI debug port reset completion in early printkJan Beulich1-1/+1
On one of my systems, several thousand iterations are needed before CMD_RESET can be observed clear after setting it. Using a much higher value here obviously cannot hurt.

On Intel platforms, we can use logical flat mode if there are <= 8 logical cpu's (irrespective of physical apic id values). This will enable simplified and efficient IPI and device interrupt routing on such platforms. Fix the relevant comments while we are at it.

2009-09-18x86, pat: don't use rb-tree based lookup in reserve_memtype()Suresh Siddha1-10/+2
Recent enhancement of rb-tree based lookup exposed a bug with the lookup mechanism in the reserve_memtype() which ensures that there are no conflicting memtype requests for the memory range. memtype_rb_search() returns an entry which has a start address <= new start address. And from here we traverse the linear linked list to check if there any conflicts with the existing mappings. As the rbtree is based on the start address of the memory range, it is quite possible that we have several overlapped mappings whose start address is much less than new requested start but the end is >= new requested end. This results in conflicting memtype mappings. Same bug exists with the old code which uses cached_entry from where we traverse the linear linked list. But the new rb-tree code exposes this bug fairly easily. For now, don't use the memtype_rb_search() and always start the search from the head of linear linked list in reserve_memtype(). Linear linked list for most of the systems grow's to few 10's of entries(as we track memory type of RAM pages using struct page). So we should be ok for now. We still retain the rbtree and use it to speed up free_memtype() which doesn't have the same bug(as we know what exactly we are searching for in free_memtype). Also use list_for_each_entry_from() in free_memtype() so that we start the search from rb-tree lookup result.

2009-09-17MIPS: Allow kernel use of LL/SC to be separate from the presence of LL/SC.David Daney6-47/+50
On some CPUs, it is more efficient to disable and enable interrupts in the kernel rather than use ll/sc for atomic operations. But if we were to set cpu_has_llsc to false, we would break the userspace futex interface (in asm/futex.h). We separate the two concepts, with a new predicate kernel_uses_llsc, that lets us disable the kernel's use of ll/sc while still allowing the futex code to use it. Also there were a couple of cases in bitops.h where we were using ll/sc unconditionally even if cpu_has_llsc were false.

This machtype kernel command line argument will be used later to share the same kernel image file between two different machines(menglong & yeeloong) made by lemote. Thanks very much to Zhang Le for cleaning up the machtype implementation. Signed-off-by: Wu Zhangjin <wuzhangjin@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Loongson: Split common loongson source code outWu Zhangjin24-133/+351
To share common loongson source code between all of the loongson-based machines. there is a need to split it out of the fuloong-2e/ directory. at the same time, other according tuning is needed. the machine-specific parts are defined as macros in relative header file, pci.h, mem.h, machine.h.

2009-09-17MIPS: Loongson: Change naming methodsWu Zhangjin25-90/+73
To make source code of loongson sharable to the machines(such as gdium) made by the other companies, we rename arch/mips/lemote to arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to FULOONG2E to make it distinguishable to the future FULOONG2F. and also, some other relative tuning is needed.
