Subject: [PATCH] kexec-tools: powerpc: Fix pointer declarations in
read_memory_region_limits()
Fixes the following two build errors on 32-bit PowerPC:
kexec/arch/ppc/kexec-ppc.c: In function 'read_memory_region_limits':
kexec/arch/ppc/kexec-ppc.c:106:11: error: assignment to 'long long unsigned int *' from incompatible pointer type 'long unsigned int *' [-Wincompatible-pointer-types]
106 | p = (unsigned long*)buf;
| ^
kexec/arch/ppc/kexec-ppc.c: In function 'read_memory_region_limits':
kexec/arch/ppc/kexec-ppc.c:112:19: error: assignment to 'long unsigned int *' from incompatible pointer type 'long long unsigned int *' [-Wincompatible-pointer-types]
112 | p = (unsigned long long *)p + 1;
| ^
