RFC 3041 describes an algorithm to generate random interface identifier. In RFC 3041bis, it is allowed to use different algorithm than one described in RFC 3041. So, let's use our standard pseudo random algorithm to simplify our implementation. Signed-off-by:

Since addrconf_add_dev() has already called addrconf_add_mroute() to added route for multicast prefix, there's no point to call it again in addrconf_ip6_tnl_config(). Signed-off-by:

We only need to write an invalid tag every 16 bytes, so taking advantage of this can save many instructions compared to the simple memset() call we make now. A prefetching implementation is implemented for sun4u and a block-init store version if implemented for Niagara. The next trick is to be able to perform an init and a copy_tsb() in parallel when growing a TSB table. Signed-off-by: -

online_page() is straightforward, and then add a dummy remove_memory() that returns -EINVAL just like i386. There is no point in implementing remove_memory() since __remove_pages() has no implementation either. Signed-off-by: -

Try only lightly on > 1 order allocations. If a grow fails, we are under memory pressure, so do not try to grow the TSB for this address space any more. If a > 0 order TSB allocation fails on a new fork, retry using a 0 order allocation. Signed-off-by: -

Put it one page below the top of the 32-bit address space. This gives us ~16MB more address space to work with. Signed-off-by: -

Currently allocations are very constrained for 32-bit processes. It grows down-up from 0x70000000 to 0xf0000000 which gives about 2GB of stack + dynamic mmap() space. So support the top-down method, and we need to override the generic helper function in order to deal with D-cache coloring. With these changes I was able to squeeze out a mmap() just over 3.6GB in size in a 32-bit process. Signed-off-by: -

This is good for up to %50 performance improvement of some test cases. The problem has been the race conditions, and hopefully I've plugged them all up here. 1) There was a serious race in switch_mm() wrt. lazy TLB switching to and from kernel threads. We could erroneously skip a tsb_context_switch() and thus use a stale TSB across a TSB grow event. There is a big comment now in that function describing exactly how it can happen. 2) All code paths that do something with the TSB need to be guarded with the mm->context.lock spinlock. This makes page table flushing paths properly synchronize with both TSB growing and TLB context changes. 3) TSB growing events are moved to the end of successful fault processing. Previously it was in update_mmu_cache() but that is deadlock prone. At the end of do_sparc64_fault() we hold no spinlocks that could deadlock the TSB grow sequence. We also have dropped the address space semaphore. While we're here, add prefetching to the copy_tsb() routine and put it in assembler into the tsb.S file. This piece of code is quite time critical. There are some small negative side effects to this code which can be improved upon. In particular we grab the mm->context.lock even for the tsb insert done by update_mmu_cache() now and that's a bit excessive. We can get rid of that locking, and the same lock taking in flush_tsb_user(), by disabling PSTATE_IE around the whole operation including the capturing of the tsb pointer and tsb_nentries value. That would work because anyone growing the TSB won't free up the old TSB until all cpus respond to the TSB change cross call. I'm not quite so confident in that optimization to put it in right now, but eventually we might be able to and the description is here for reference. This code seems very solid now. It passes several parallel GCC bootstrap builds, and our favorite "nut cruncher" stress test which is a full "make -j8192" build of a "make allmodconfig" kernel. That puts about 256 processes on each cpu's run queue, makes lots of process cpu migrations occur, causes lots of page table and TLB flushing activity, incurs many context version number changes, and it swaps the machine real far out to disk even though there is 16GB of ram on this test system. :-) Signed-off-by:
