powerpc/perf: Update perf_regs structure to include SIER
On each sample, Sample Instruction Event Register (SIER) content is saved in pt_regs. SIER does not have a entry as-is in the pt_regs but instead, SIER content is saved in the "dar" register of pt_regs. Patch adds another entry to the perf_regs structure to include the "SIER" printing which internally maps to the "dar" of pt_regs. It also check for the SIER availability in the platform and present value accordingly Signed-off-by: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
