2010-11-18x86: UV: Address interrupt/IO port operation conflictDimitri Sivanich
This patch for SGI UV systems addresses a problem whereby interrupt transactions being looped back from a local IOH, through the hub to a local CPU can (erroneously) conflict with IO port operations and other transactions. To workaound this we set a high bit in the APIC IDs used for interrupts. This bit appears to be ignored by the sockets, but it avoids the conflict in the hub.

2010-11-18x86: Use online node real index in calulate_tbl_offset()Yinghai Lu
Found a NUMA system that doesn't have RAM installed at the first socket which hangs while executing init scripts. bisected it to: | commit 932967202182743c01a2eee4bdfa2c42697bc586 | Author: Shaohua Li <shaohua.li@intel.com> | Date: Wed Oct 20 11:07:03 2010 +0800 | | x86: Spread tlb flush vector between nodes It turns out when first socket is not online it could have cpus on node1 tlb_offset set to bigger than NUM_INVALIDATE_TLB_VECTORS. That could affect systems like 4 sockets, but socket 2 doesn't have installed, sockets 3 will get too big tlb_offset. Need to use real online node idx.

2010-11-18sh: Use GCC __builtin_prefetch() to implement prefetch().Giuseppe CAVALLARO
GCC's __builtin_prefetch() was introduced a long time ago, all supported GCC versions have it. So this patch is to use it for implementing the prefetch on SH2A and SH4. The current prefetch implementation is almost equivalent with __builtin_prefetch. The third parameter in the __builtin_prefetch is the locality that it's not supported on SH architectures. It has been set to three and it should be verified if it's suitable for SH2A as well. I didn't test on this architecture. The builtin usage should be more efficient that an __asm__ because less barriers, and because the compiler doesn't see the inst as a "black box" allowing better code generation. This has been already done on other architectures (see the commit: 0453fb3c528c5eb3483441a466b24a4cb409eec5). Many thanks to Christian Bruel <christain.bruel@st.com> for his support on evaluate the impact of the gcc built-in on SH4 arch. No regressions found while testing with LMbench on STLinux targets.

2010-11-18drm/ttm: Fix up a theoretical deadlockThomas Hellstrom
A process suspended waiting for a higher sequence or no sequence to unreserve, a bo may be beaten to the reservation by a process with a lower sequence. In that case the first process should give up trying to reserve and return -EAGAIN. In order for that to happen, we must wake waiting processes when we change sequence, so that they have a chance to detect the new sequence.

2010-11-18drm/radeon/kms: fix tiling info on evergreenAlex Deucher
We aren't currently using tiling in userspace on evergreen, but the info we currently return for the tiling info query (gb_addr_config) is no adequate for userspace tiling alignment calculations. It does not contain the bank info. Create a custom tiling info dword with all the necessary info (num channels, num banks, group size, row size).
