Pull SCSI fixes from James Bottomley:
 "Two minor fixes in the hisi_sas driver which only impact enterprise
  style multi-expander and shared disk situations and no core changes"

* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
  scsi: hisi_sas: Set a port invalid only if there are no devices attached when refreshing port id
  scsi: hisi_sas: Use abort task set to reset SAS disks when discovered

Pull xen fixes from Juergen Gross:

 - two cleanup patches

 - a fix of a memory leak in the Xen pvfront driver

 - a fix of a locking issue in the Xen hypervisor console driver

* tag 'for-linus-6.2-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
  xen/pvcalls: free active map buffer on pvcalls_front_free_map
  hvc/xen: lock console list traversal
  x86/xen: Remove the unused function p2m_index()
  xen: make remove callback of xen driver void returned

Currently the driver sets the port invalid if one phy in the port is not
enabled, which may cause issues in expander situation. In directly attached
situation, if phy up doesn't occur in time when refreshing port id, the
port is incorrectly set to invalid which will also cause disk lost.

Therefore set a port invalid only if there are no devices attached to the
port.

Currently clear task set is used to abort all commands remaining in the
disk when the SAS disk is discovered, and if the disk is discovered by two
initiators, other I_T nexuses are also affected. So use abort task set
instead and take effect only on the specified I_T nexus.

Grab the ATA port lock in sas_ata_device_link_abort() before calling
ata_link_abort() as outlined in this function's locking requirements.

The reserved tags were put in the lower region of the tagset in commit
f7d190a94e35 ("scsi: hisi_sas: Put reserved tags in lower region of
tagset"). However, only the allocate function was changed, freeing was not
handled. This resulted in a failure to boot:

Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )

    $ patch -p1 < /tmp/t.patch
