[PATCH V1 06/19] perf tools: Fix kernel_start for PTI on x86

On x86_64, PTI entry trampolines are less than the start of kernel text, but still above 2^63. So leave kernel_start = 1ULL << 63 for x86_64. Signed-off-by: Adrian Hunter --- tools/perf/util/machine.c | 16 +++- tools/perf/util/machine.h | 2 ++ 2 files
