[PATCH] USB: hcd suspend uses pm_message_t

This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs.  Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ...  the others relate to how the EHCI
code walks in-memory data structures.  (There's a minor bug fixed there too
...  affecting the big-endian sysfs async schedule dump.)

[PATCH] usb suspend updates (interface suspend)

This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t".  This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:

    - <linux/usb.h> and usbcore, signature change

    - Some drivers only changed the signature, net effect this just
      shuts up "sparse -Wbitwise":
* hid-core
* stir4200

    - Two network drivers did that, and also grew slightly more
      featureful suspend code ... they now properly shut down
      their activities.  (As should stir4200...)
* pegasus
* usbnet

Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

[PATCH] usb resume fixes

This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.

    - Cope with pm_message_t replacing the target system state.
      This is actually a loss of functionality; PCI D1 and D2
      states will no longer be used, and it's no longer knowable
      that D3cold is on the way so power will be lost.

    - Most importantly, some of the resume paths are reworked and
      cleaned up.  They're now an exact mirror of suspend paths,
      and more care is taken to ensure the hardware is reactivated
      before the hardware re-enables interrupts.

Plus comment and diagnostic cleanups; there are some nasty cases here
especially combined with swsusp, now they're somewhat commented.

[PATCH] SELinux: fix deadlock on dcache lock

This fixes a deadlock on the dcache lock detected during testing at IBM
by moving the logging of the current executable information from the
SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
helper) for processing upon syscall exit.

For consistency, the patch also removes the logging of other
task-related information from avc_audit, deferring handling to
audit_log_exit instead.

This allows simplification of the avc_audit code, allows the exe
information to be obtained more reliably, always includes the comm
information (useful for scripts), and avoids including bogus task
information for checks performed from irq or softirq.

[PATCH] sparc64: Reduce ptrace cache flushing

We were flushing the D-cache excessively for ptrace() processing
and this makes debugging threads so slow as to be totally unusable.

All process page accesses via ptrace() go via access_process_vm().
This routine, for each process page, uses get_user_pages().  That
in turn does a flush_dcache_page() on the child pages before we
copy in/out the ptrace request data.

Therefore, all we need to do after the data movement is:

1) Flush the D-cache pages if the kernel maps the page to a different
   color than userspace does.
2) If we wrote to the page, we need to flush the I-cache on older cpus.

Previously we just flushed the entire cache at the end of a ptrace()
request, and that was beyond stupid.

[PATCH] sparc: Fix PTRACE_CONT bogosity

SunOS aparently had this weird PTRACE_CONT semantic which
we copied.  If the addr argument is something other than
1, it sets the process program counter to whatever that
value is.

This is different from every other Linux architecture, which
don't do anything with the addr and data args.

This difference in particular breaks the Linux native GDB support
for fork and vfork tracing on sparc and sparc64.

There is no interest in running SunOS binaries using this weird
PTRACE_CONT behavior, so just delete it so we behave like other
platforms do.

This reverts a fs/char_dev.c patch that was merged into BK on March 3.

fails rudely during PCMCIA initialization or other register_chrdev()
calls, because it doesn't "degrade to linked list".  This keeps whole
subsystems from working.

A real fix to that "temporary" code should be possible, using some better
scheme to allocate major numbers, but it's not something I want to spend

[PATCH] jbd dirty buffer leak fix

This fixes the lots-of-fsx-linux-instances-cause-a-slow-leak bug.

It's been there since 2.6.6, caused by:

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.5/2.6.5-mm4/broken-out/jbd-move-locked-buffers.patch

That patch moves under-writeout ordered-data buffers onto a separate journal
list during commit.  It took out the old code which was based on a single
list.

The old code (necessarily) had logic which would restart I/O against buffers
which had been redirtied while they were on the committing transaction's
t_sync_datalist list.  The new code only writes buffers once, ignoring
redirtyings by a later transaction, which is good.

But over on the truncate side of things, in journal_unmap_buffer(), we're
treating buffers on the t_locked_list as inviolable things which belong to the
committing transaction, and we just leave them alone during concurrent
truncate-vs-commit.

The net effect is that when truncate tries to invalidate a page whose buffers
are on t_locked_list and have been redirtied, journal_unmap_buffer() just
leaves those buffers alone.  truncate will remove the page from its mapping
and we end up with an anonymous clean page with dirty buffers, which is an
illegal state for a page.  The JBD commit will not clean those buffers as they
are removed from t_locked_list.  The VM (try_to_free_buffers) cannot reclaim
these pages.

The patch teaches journal_unmap_buffer() about buffers which are on the
committing transaction's t_locked_list.  These buffers have been written and
I/O has completed.  We can take them off the transaction and undirty them
within the context of journal_invalidatepage()->journal_unmap_buffer().

[PATCH] IB/mthca: add support for new MT25204 HCA

Decouple table of HCA features from exact HCA device type.  Add a current FW
version field so we can warn when someone is using old FW.  Add support for
new MT25204 HCA.

Remove the warning about mem-free support, since it should be pretty solid at
this point.

Tavor, MTTs for FMR are separate from regular MTTs, and are reserved at driver
initialization.  This is done to limit the amount of virtual memory needed to

may be used for FMR or for regular MR.

[PATCH] IB/mthca: fix MTT allocation in mem-free mode

Fix bug in MTT allocation in mem-free mode.

I misunderstood the MTT size value returned by the firmware -- it is really
the size of a single MTT entry, since mem-free mode does not segment the MTT
as the original firmware did.  This meant that our MTT addresses ended up
being off by a factor of 8.  This meant that our MTT allocations might
overlap, and so we could overwrite and corrupt earlier memory regions when
writing new MTT entries.

We fix this by always using our 64-byte MTT segment size.  This allows some
simplification of the code as well, since there's no reason to put the MTT
segment size in a variable -- we can always use our enum value directly.

In the new io infrastructure, all of our operators are expecting the

However, there are a fair few devices and busses in the world that are
actually Big Endian.  There's even evidence that some of these BE bus and
chip types are attached to LE systems.  Thus, there's a need for a BE

[PATCH] Fix comment in list.h that refers to nonexistent API

The hlist_for_each_entry_rcu() comment block refers to a nonexistent
hlist_add_rcu() API, needs to change to hlist_add_head_rcu().
