There were some problem in ipq8074 Gen2 PCIe phy init sequence. 1. Few register values were wrongly updated in the phy init sequence. 2. The register QSERDES_RX_SIGDET_CNTRL is a RX tuning parameter register which is added in serdes table causing the wrong register was getting updated. 3. Clocks and resets were not added in the phy init. Fix these to make Gen2 PCIe port on ipq8074 devices to work.

regfield handling in current driver code is made complicated by having a separate regfield variable for each field which is allocated individually. This quickly gets unwieldy once number of regfields increase. Instead, use an array of regfields which are allocated in a loop. Signed-off-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).

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. Cc: stable@vger.kernel.org # v5.8 Reported-by:
