Subject: perf tools: Fix parsing of 64 bit raw config value for 32 bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b527bab59be7ca2154f644fcc4b9e3c267a6d855;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

perf tools: Fix parsing of 64 bit raw config value for 32 bit

perf record fails on 32 bit with:

 invalid or unsupported event: 'r40000F7E0'

Fixing this by parsing 64 bit num values.
