fs/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types
Some fs compat system calls have unsigned long parameters instead of compat_ulong_t. In order to allow the COMPAT_SYSCALL_DEFINE macro generate code that performs proper zero and sign extension convert all 64 bit parameters their corresponding 32 bit counterparts. compat_sys_io_getevents() is a bit different: the non-compat version has signed parameters for the "min_nr" and "nr" parameters while the compat version has unsigned parameters. So change this as well. For all practical purposes this shouldn't make any difference (doesn't fix a real bug). Also introduce a generic compat_aio_context_t type which can be used everywhere. The access_ok() check within compat_sys_io_getevents() got also removed since the non-compat sys_io_getevents() should be able to handle everything anyway.
