Subject[PATCH] powerpc/fixmap: Fix the size of the early debug area
Date
Commit ("03fd42d458fb powerpc/fixmap: Fix FIX_EARLY_DEBUG_BASE when
page size is 256k") reworked the setup of the early debug area and
mistakenly replaced 128 * 1024 by SZ_128.

Change to SZ_128K to restore the original 128 kbytes size of the area.

Fixes: 03fd42d458fb ("powerpc/fixmap: Fix FIX_EARLY_DEBUG_BASE when page size is 256k")
