Subject: tools/perf: Fix sorting for 64bit entries
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=354cc40e3b0981c38ba2ce2964954480e6c03c37;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tools/perf: Fix sorting for 64bit entries

Some of the node comparisons in hist.c dropped the upper
32bit by using an int variable to store the compare
result. This broke various 64bit fields, causing
incorrect collapsing (found for the TSX transaction field)

Just use int64_t always.
