Cover letter [PATCH 4.14 0/5] perf machine: Workaround missing maps for x86 PTI entry trampolines
Hi
x86 PTI trampolines were backported to 4.14, refer
commit: c631a16e5b84521ae80ab10d47cd6ccd2afc6817 ("x86/entry/64:
Create a per-CPU SYSCALL entry trampoline")
so the corresponding perf tools workaround also needs to be backported. Here are 5 patches for 4.14 stable backported from 4.18, to address that.
Regards
Adrian
