Subject: tools headers: Remove unused kvm_perf.h copies
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=a85ac2dae6bf8050deaf9839e4c0328756b48720;p=users%2Fhch%2Fmisc.git

tools headers: Remove unused kvm_perf.h copies

These have been unused since commit 162607ea20fa ("perf kvm/{x86,s390}:
Remove dependency on uapi/kvm_perf.h") in favour of dynamic discovery.

Remove the unused headers to reduce consistency checking overhead and
noise.
