[PATCH 4.19 113/120] powerpc/64s: Fix instruction encoding for lis in ppc_function_entry()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

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.
