Anton Blanchard de4376c284 powerpc: Preload application text segment instead of TASK_UNMAPPED_BASE ... TASK_UNMAPPED_BASE is not used with the new top down mmap layout. We can reuse this preload slot by loading in the segment at 0x10000000, where almost all PowerPC binaries are linked at. On a microbenchmark that bounces a token between two 64bit processes over pipes and calls gettimeofday each iteration (to access the VDSO), both the 32bit and 64bit context switch rate improves (tested on a 4GHz POWER6): 32bit: 273k/sec -> 283k/sec 64bit: 277k/sec -> 284k/sec Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>		2009-08-20 10:12:26 +10:00
