[PATCH 02/13] perf/core: Extend perf_sample_regs_intr() to include perf_arch_regs update

Show all headers | View raw

Extend perf_sample_regs_intr() to support the updates needed for
perf_arch_reg structure and perf_arch_regs_mask. Also add code to
init the arch_regs_mask to zero incase of regs_user in
perf_sample_regs_user(). Ideally this should be done in perf_sample_data_init,
but due to commit 2565711fb7d7 ("perf: Improve the perf_sample_data struct layout")
moving it to this function.
