Previously we enabled writes to the DBI read-only registers so the Class Code fix in dw_pcie_setup_rc() would work. But now dw_pcie_setup_rc() enables write permission itself, so we don't need to do it here. Stop enabling writes to the DBI read-only registers.

dw_pcie_setup_rc() contains fixes to update the Class Code and Interrupt Pin registers, but the fixes don't actually work because these registers are read-only.

The read-only DBI registers can be written only when the "Write to RO Registers Using DBI" (DBI_RO_WR_EN) field of MISC_CONTROL_1_OFF is set. Add accessors to enable and disable write permission, and use them instead of accessing MISC_CONTROL_1_OFF directly.

We will use the generic ls_pcie_link_up() and ls_pcie_host_init() from device-specific routines. Move the generic functions earlier in the file so we won't need forward declarations.

We called dw_pcie_setup_rc() from the ls1021a host init function, but not from the common ls_pcie_host_init() function, so platforms other than ls1021a still depended on initialization by the bootloader. Call dw_pcie_setup_rc() from ls_pcie_host_init() to reduce dependencies on the bootloader.

If the interrupt status is cleared before it is handled, it is possible that another interrupt will trigger while servicing the previous one.

host_init() should detect and propagate errors from post_init(). In addition, by acknowledging that post_init() can fail we must disable the post_init() resources in a step separate from the deinit, so that we don't try to disable the post_init() resources a second time.

nfs4_retry_setlk() sets the task's state to TASK_INTERRUPTIBLE within the same region protected by the wait_queue's lock after checking for a notification from CB_NOTIFY_LOCK callback. However, after releasing that lock, a wakeup for that task may race in before the call to freezable_schedule_timeout_interruptible() and set TASK_WAKING, then freezable_schedule_timeout_interruptible() will set the state back to TASK_INTERRUPTIBLE before the task will sleep. The result is that the task will sleep for the entire duration of the timeout. Since we've already set TASK_INTERRUPTIBLE in the locked section, just use freezable_schedule_timout() instead.

When a lba either hits the cache or corresponds to an empty entry in the L2P table, we need to advance the bio according to the position in which the lba is located. Otherwise, we will copy data in the wrong page, thus causing data corruption for the application. In case of a cache hit, we assumed that bio->bi_iter.bi_idx would contain the correct index, but this is no necessarily true. Instead, use the local bio advance counter and iterator. This guarantees that lbas hitting the cache are copied into the right bv_page. In case of an empty L2P entry, we omitted to advance the bio. In the cases when the same I/O also contains a cache hit, data corresponding to this lba will be copied to the wrong bv_page. Fix this by advancing the bio as we do in the case of a cache hit.
