[PATCH] x86/fsgsbase/64: Use TASK_SIZE_MAX for FSBASE/GSBASE upper limits

The GSBASE upper limit exists to prevent user code from confusing the paranoid idtentry path. The FSBASE upper limit is just for consistency. There's no need to enforce a smaller limit for 32-bit tasks. Just use TASK_SIZE_MAX. This simplifies the logic and will save a few bytes of code.

[RFC 08/13] mm, compaction: simplify contended compaction handling

Async compaction detects contention either due to failing trylock on zone->lock or lru_lock, or by need_resched(). Since 1f9efdef4f3f ("mm, compaction: khugepaged should not give up due to need_resched()") the code got quite complicated to distinguish these two up to the __alloc_pages_slowpath()

[PATCH v2 6/9] perf tools: Promote proper messages for cross-platform unwind

Currently, perf script uses host unwind methods to parse perf.data callchain info regardless of the target architecture. So we get wrong result and no promotion when unwinding callchains of x86(32-bit) on x86(64-bit) machine. This patch shows proper error messages when we do remote unwind

[PATCH v2 7/9] perf callchain: Add support for cross-platform unwind

Use thread specific unwind ops to unwind cross-platform callchains. Before this patch, unwind methods is suitable for local unwind, this patch changes the fixed methods to thread/map related. Each time a map is inserted, we find the target arch and see if this platform can be remote unwind. In

[PATCH v2 1/9] perf tools: Omit DWARF judgement when recording dwarf callchain

There is no need to check for DWARF unwinding support when using the 'dwarf' callchain record method, as this will only ask the kernel to collect stack dumps for later DWARF CFI processing, which can be done in another machine, where the support for DWARF unwinding need to be present.
