parisc: io_pgetevents_time64() needs compat syscall in 32-bit compat mode
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.
