From 501fe299826ead2cfa2046b5c244e36de254ec6a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 1 Sep 2022 12:02:15 +1000 Subject: [PATCH] selftests/powerpc: Skip 4PB test on 4K PAGE_SIZE systems Systems using the hash MMU with a 4K page size don't support 4PB address space, so skip the test because the bug it tests for can't be triggered.
