* [PATCH] x86: rewrite SMP TSC sync codeIngo Molnar2007-02-16
| | | | | | | | | | | | | | | | | | | | | | make the TSC synchronization code more robust, and unify it between x86_64 and i386. The biggest change is the removal of the 'fix up TSCs' code on x86_64 and i386, in some rare cases it was /causing/ time-warps on SMP systems. The new code only checks for TSC asynchronity - and if it can prove a time-warp (if it can observe the TSC going backwards when going from one CPU to another within a critical section), then the TSC clock-source is turned off. The TSC synchronization-checking code also got moved into a separate file.

* [PATCH] uml: fix 2.6.20 hangJeff Dike2007-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A previous cleanup misused need_poll, which had a fairly broken interface. It implemented a growable array, changing the used elements count itself, but leaving it up to the caller to fill in the actual elements, including the entire array if the array had to be reallocated. This worked because the previous users were switching between two such structures, and the elements were copied from the inactive array to the active array after making sure the active array had enough room. maybe_sigio_broken was made to use need_poll, but it was operating on a single array, so when the buffer was reallocated, the previous contents were lost. This patch makes need_poll implement more sane semantics. It merely assures that the array is of the proper size and that the contents are preserved. It is up to the caller to adjust the used elements count and to ensure that the proper elements are resent. This manifested itself as a hang in 2.6.20 as the uninitialized buffer convinced UML that one of its own file descriptors didn't support SIGIO and needed to be watched by poll in a separate thread. The result was an interrupt flood as control traffic over this descriptor sparked interrupts, which resulted in more control traffic, ad nauseum.

| * sh: Lazy dcache writeback optimizations.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the lazy dcache handling to the model described in Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a bonus, this slightly cuts down on the cache flushing frequency. With that and the PTEA handling out of the way, the update_mmu_cache() implementations can be consolidated, and we no longer have to worry about which configuration the cache is in for the SH7705 case. And finally, explicitly disable the lazy writeback on SMP (SH-4A). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Use a jump call table for debug trap handlers.Paul Mundt2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rips out most of the needlessly complicated sh_bios and kgdb trap handling, and forces it all through a common fast dispatch path. As more debug traps are inserted, it's important to keep them in sync for all of the parts, not just SH-3/4. As the SH-2 parts are unable to do traps in the >= 0x40 range, we restrict the debug traps to the 0x30-0x3f range on all parts, and also bump the kgdb breakpoint trap down in to this range (from 0xff to 0x3c) so it's possible to use for nommu. Optionally, this table can be padded out to catch spurious traps for SH-3/4, but we don't do that yet.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

My understanding is that the VDSO changes in 2.6.20-rc7 were not fully cooked, in that with that config option enabled VDSO_SYM(x) now equals x, meaning that an address in the fixmap area is now being passed to apps via AT_SYSINFO. However, the page is mapped with PAGE_READONLY rather than PAGE_READONLY_EXEC. I'm not certain whether having app code go through the fixmap area is intended, but in case it is here is the simple patch that makes things work again.
