Subject: [PATCH] powerpc/64s: Don't read H_BLOCK_REMOVE characteristics in radix mode
Date: Fri, 20 May 2022 17:57:21 +0200 [thread overview]
Message-ID: <20220520155721.10211-1-ldufour@linux.ibm.com> (raw)
There is no need to read the H_BLOCK_REMOVE characteristics when running in
Radix mode because this hcall is never called.
