st_kim_ref() does not take care of the fact that platform_get_drvdata() might return NULL. On AM437x EVM, this causes the platform to stop booting as soon as the module is inserted.

This patch fixes the issue by checking for NULL return value. Oops log follows.

Modifying a non-existent slot is not allowed.  Also check that the

Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Before commit 0e60b079 (kvm: change memslot sorting rule from size
to GFN, 2014-12-01), the memslots' sorting key was npages, meaning
that a valid memslot couldn't have its sorting key equal to zero.
On the other hand, a valid memslot can have base_gfn == 0, and invalid
memslots are identified by base_gfn == npages == 0.

Because of this, commit 0e60b079 broke the invariant that invalid
memslots are at the end of the mslots array.  When a memslot with
base_gfn == 0 was created, any invalid memslot before it were left
in place.

This can be fixed by changing the insertion to use a ">=" comparison
instead of "<=", but some care is needed to avoid breaking the case
of deleting a memslot; see the comment in update_memslots.

Thanks to Tiejun Chen for posting an initial patch for this bug.

The __ldcw macro has a problem when its argument needs to be reloaded from
memory. The output memory operand and the input register operand both need to
be reloaded using a register in class R1_REGS when generating 64-bit code.
This fails because there's only a single register in the class. Instead, use a
memory clobber. This also makes the __ldcw macro a compiler memory barrier.

to support HW which provides a total of more than 15 stream DMA engines

field (and the whole SDxCTL register) and as a result usage of
Reserved value 0 in the SDxCTL.STRM field which confuses HDA controller.

  while), one patch fixes a problem where we weren't recording pathnames
  correctly, and one fixes a problem with PID based filters.

  In general I don't think there is anything controversial with this

  audit: correctly record file names with different path name types
  audit: use supplied gfp_mask from audit_buffer in kauditd_send_multicast_skb
  audit: don't attempt to lookup PIDs when changing PID filtering audit rules

A regression was caused by commit 780a7654:
	 audit: Make testing for a valid loginuid explicit.
(which in turn attempted to fix a regression caused by e1760bd5)

When audit_krule_to_data() fills in the rules to get a listing, there was a
missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.

This broke userspace by not returning the same information that was sent and
expected.

The rule:
	auditctl -a exit,never -F auid=-1
gives:
	auditctl -l
		LIST_RULES: exit,never f24=0 syscall=all
when it should give:
		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all

Tag it so that it is reported the same way it was set.  Create a new
private flags audit_krule field (pflags) to store it that won't interact with
the public one from the API.
