	The syscall __NR_pselect6_time64 (32-bit) or __NR_pselect6 (64-bit) is used as default. For architectures with __ASSUME_TIME64_SYSCALLS the 32-bit fallback uses __NR_pselec6. To accomodate microblaze missing pselect6 support on kernel older than 3.15 the fallback is moved to its own function to the microblaze specific implementation can override it. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel). Reviewed-by: Alistair Francis <alistair.francis@wdc.com>

2019-11-22	misc: Set generic pselect as ENOSYS	Adhemerval Zanella
	The generic pselect implementation has the very specific race condition that motived the creation of the pselect syscall (no atomicity in signal mask set/reset). Using it as generic implementation is counterproductive Also currently only microblaze uses it as fallback when used on kernel prior 3.15. This patch moves the generic implementation to a microblaze specific one, sets the generic internal as a ENOSYS, and cleanups the Linux generic implementation. The microblaze implementation mimics the previous Linux generic one, where it either uses pselect6 directly if __ASSUME_PSELECT or a first try pselect6 then the fallback otherwise. Checked on x86_64-linux-gnu and microblaze-linux-gnu.
