[PATCH 8/9] target/ppc: silence the compiler warnings


From: Chen Qun
Subject: [PATCH 8/9] target/ppc: silence the compiler warnings
Date: Wed, 28 Oct 2020 12:18:18 +0800

When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
target/ppc/mmu_helper.c: In function ‘dump_mmu’:
target/ppc/mmu_helper.c:1351:12: warning: this statement may fall through 
[-Wimplicit-fallthrough=]
 1351 |         if (ppc64_v3_radix(env_archcpu(env))) {
      |            ^
target/ppc/mmu_helper.c:1358:5: note: here
 1358 |     default:
      |     ^~~~~~~

Add the corresponding "fall through" comment to fix it.
