Please review: https://lists.ubuntu.com/archives/kernel-
team/2023-November/147184.html
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

Title:
Turning COMPAT_32BIT_TIME off on ppc64el
Status in The Ubuntu-power-systems project:
In Progress
Status in linux package in Ubuntu:
In Progress
Bug description:
This will prevent existing 32-bit powerpcle binaries to operate
correctly, if they are still using 32bit time. And even exists?
24.04 LTS is likely to be used for 10 years. And if allowed to overrun
and remain active in the field in 2038 can lead to catastrophic
failure in the field due to these syscalls enabled and used.
I would like to request if we can turn off COMPAT_32BIT_TIME on every
architecture, thus this will be arch by arch bug report, and arch by
arch decision.
This needs to be a per-arch decision, potentially taking into
consideration bi-arch userspace support.
config COMPAT_32BIT_TIME
bool "Provide system calls for 32-bit time_t"
default !64BIT || COMPAT
help
This enables 32 bit time_t support in addition to 64 bit time_t support.
This is relevant on all 32-bit architectures, and 64-bit architectures
as part of compat syscall handling.
