For all syscalls in 32-bit compat mode on 64-bit kernels the upper 32-bits of the 64-bit registers are zeroed out, so a negative 32-bit signed value will show up as positive 64-bit signed value. This behaviour breaks the io_pgetevents_time64() syscall which expects signed 64-bit values for the "min_nr" and "nr" parameters. Fix this by switching to the compat_sys_io_pgetevents_time64() syscall, which uses "compat_long_t" types for those parameters.
