Roland McGrath b599316492 elfcore-compat fix uid/gid types
I overlooked the difference between __kernel_uid_t and uid_t when defining
struct compat_elf_prpsinfo.  The result is a regression in 32-bit core
dumps on x86_64, where the NT_PRPSINFO note has the wrong size and layout.
This patch fixes it.
