livepatch: Fix build failure on 32 bits processors
[ Upstream commit 2f293651eca3eacaeb56747dede31edace7329d2 ]
Trying to build livepatch on powerpc/32 results in:
kernel/livepatch/core.c: In function 'klp_resolve_symbols':
kernel/livepatch/core.c:221:23: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
221 | sym = (Elf64_Sym *)sechdrs[symndx].sh_addr + ELF_R_SYM(relas[i].r_info);
| ^
kernel/livepatch/core.c:221:21: error: assignment to 'Elf32_Sym *' {aka 'struct elf32_sym *'} from incompatible pointer type 'Elf64_Sym *' {aka 'struct elf64_sym *'} [-Werror=incompatible-pointer-types]
221 | sym = (Elf64_Sym *)sechdrs[symndx].sh_addr + ELF_R_SYM(relas[i].r_info);
| ^
kernel/livepatch/core.c: In function 'klp_apply_section_relocs':

kernel/livepatch/core.c:193:44: note: expected 'Elf64_Shdr *' {aka 'struct elf64_shdr *'} but argument is of type 'Elf32_Shdr *' {aka 'struct elf32_shdr *'}
193 | static int klp_resolve_symbols(Elf64_Shdr *sechdrs, const char *strtab,
| ~~~~~~~~~~~~^~~~~~~
Fix it by using the right types instead of forcing 64 bits types.
