Rao" <naveen.n.rao@xxxxxxxxxxxxxxxxxx> Date: Thu, 4 Mar 2021 07:34:11 +0530 Subject: powerpc/64s: Fix instruction encoding for lis in ppc_function_entry() From: Naveen N. Rao <naveen.n.rao@xxxxxxxxxxxxxxxxxx> commit cea15316ceee2d4a51dfdecd79e08a438135416c upstream. 'lis r2,N' is 'addis r2,0,N' and the instruction encoding in the macro LIS_R2 is incorrect (it currently maps to 'addis r0,r2,N'). Fix the same.
