kgdb,ppc: Fix regression in evr register handling
Commit ff10b88b5a05c8f1646dd15fb9f6093c1384ff6d (kgdb,ppc: Individual
register get/set for ppc) introduced a problem where memcpy was used
incorrectly to read and write the evr registers with a kernel that
has:
CONFIG_FSL_BOOKE=y
CONFIG_SPE=y
CONFIG_KGDB=y
This patch also fixes the following compilation problems:
arch/powerpc/kernel/kgdb.c: In function 'dbg_get_reg':
arch/powerpc/kernel/kgdb.c:341: error: passing argument 2 of 'memcpy' makes pointer from integer without a cast
arch/powerpc/kernel/kgdb.c: In function 'dbg_set_reg':
arch/powerpc/kernel/kgdb.c:366: error: passing argument 1 of 'memcpy' makes pointer from integer without a cast
[jason.wessel@windriver.com: Remove void * casts and fix patch header]
