+Subject: [PATCH] Add support for io_pgetevents_time64 syscall
+
+32-bit architectures that are y2038 safe don't include syscalls that use
+32-bit time_t. Instead these architectures have suffixed syscalls that
+always use a 64-bit time_t. In the case of the io_getevents syscall the
+syscall has been replaced with the io_pgetevents_time64 syscall instead.
+
+This patch changes the io_getevents() function to use the correct
+syscall based on the avaliable syscalls and the time_t size. We will
+only use the new 64-bit time_t syscall if the architecture is using a
+64-bit time_t. This is to avoid having to deal with 32/64-bit
+conversions and relying on a 64-bit timespec struct on 32-bit time_t
+platforms. As of Linux 5.3 there are no 32-bit time_t architectures
+without __NR_io_getevents. In the future if a 32-bit time_t architecture
+wants to use the 64-bit syscalls we can handle the conversion.
+
+This fixes build failures on 32-bit RISC-V.

+Subject: [PATCH] Fixup support for io_pgetevents_time64 syscall
+
+This is a fixup for the original commit 5b5e2985f355c8e99c196d9ce5d02c15bebadfbc
+"Add support for io_pgetevents_time64 syscall" that didn't correctly
+work for 32-bit architecutres with a 64-bit time_t that aren't RISC-V.
+
+For a full discussion of the issue see:
