Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes. Acked-by:

Pull io_uring fixes from Jens Axboe: "A few differerent things in here. Seems like syzbot got some more io_uring bits wired up, and we got a handful of reports and the associated fixes are in here. General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented). We're now passing tests that failed before" * tag 'io_uring-5.9-2020-08-15' of git://git.kernel.dk/linux-block: io_uring: short circuit -EAGAIN for blocking read attempt io_uring: sanitize double poll handling io_uring: internally retry short reads io_uring: retain iov_iter state over io_read/io_write calls task_work: only grab task signal lock when needed io_uring: enable lookup of links holding inflight files io_uring: fail poll arm on queue proc failure io_uring: hold 'ctx' reference around task_work queue + execute fs: RWF_NOWAIT should imply IOCB_NOIO io_uring: defer file table grabbing request cleanup for locked requests io_uring: add missing REQ_F_COMP_LOCKED for nested requests io_uring: fix recursive completion locking on oveflow flush io_uring: use TWA_SIGNAL for task_work uncondtionally io_uring: account locked memory before potential error case io_uring: set ctx sq/cq entry count earlier io_uring: Fix NULL pointer dereference in loop_rw_iter() io_uring: add comments on how the async buffered read retry works io_uring: io_async_buf_func() need not test page bit

Commit 1355c31e ("asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()") converted parisc to use generic version of pmd_alloc_one() but it missed the fact that parisc uses order-1 pages for PMD. Restore the original version of pmd_alloc_one() for parisc, just use GFP_PGTABLE_KERNEL that implies __GFP_ZERO instead of GFP_KERNEL and memset.

One case was missed in the short IO retry handling, and that's hitting -EAGAIN on a blocking attempt read (eg from io-wq context). This is a problem on sockets that are marked as non-blocking when created, they don't carry any REQ_F_NOWAIT information to help us terminate them instead of perpetually retrying.

There's a bit of confusion on the matching pairs of poll vs double poll, depending on if the request is a pure poll (IORING_OP_POLL_ADD) or poll driven retry. Add io_poll_get_double() that returns the double poll waitqueue, if any, and io_poll_get_single() that returns the original poll waitqueue. With that, remove the argument to io_poll_remove_double(). Finally ensure that wait->private is cleared once the double poll handler has run, so that remove knows it's already been seen.
