ppc64le is exclusively little endian and 64-bit, thus there is no need
for COMPAT_32BIT_TIME, nor COMPAT.
diffconfig result of these changes is:
-ARCH_MMAP_RND_COMPAT_BITS 13
-ARCH_WANT_COMPAT_IPC_PARSE_VERSION y
-ARCH_WANT_OLD_COMPAT_IPC y
-COMPAT_BINFMT_ELF y
-COMPAT_NETLINK_MESSAGES y
-COMPAT_OLD_SIGACTION y
-HAVE_ARCH_MMAP_RND_COMPAT_BITS y
-KVM_COMPAT y
-NETFILTER_XTABLES_COMPAT y
-SYSVIPC_COMPAT y
-VDSO32 y
COMPAT y -> n
COMPAT_32BIT_TIME y -> n
+ARCH_HAS_SYSCALL_WRAPPER y
+INTERRUPT_SANITIZE_REGISTERS y
What confused me, if the above combination is even valid or just pure
dead code.
Is it really possible to run 32bit big-endian KVM on a 64bit
little-endian POWER?
Or is Kconfig slightly buggy and should be fixed up to prevent
offering COMPAT options when little-endian 64bit POWER kernel is being
configured?
