[PATCH v2] powerpc/kdump: Ignore failure in enabling big endian exception during crash

2014-12-18 Thread Hari Bathini
In LE kernel, we currently have a hack for kexec that resets the exception endian before starting a new kernel as the kernel that is loaded could be a big endian or a little endian kernel.

[PATCH v3] powerpc/book3s: Fix flush_tlb cpu_spec hook to take a generic argument.

2014-12-18 Thread Mahesh J Salgaonkar
From: Mahesh Salgaonkar The flush_tlb hook in cpu_spec was introduced as a generic function hook to invalidate TLBs. But the current implementation of flush_tlb hook takes IS (invalidation selector) as an argument which is architecture dependent. Hence, It is not right to have a generic routine w
