Subject: [PATCH] selftests/powerpc: fix spelling errors across test sources
Fix a number of minor spelling mistakes in selftests/powerpc sources,
including ptrace, tm, pmu, math, alignment, and gzip tests. These
changes improve readability of test messages and comments without
affecting functionality as only comments were edited.
