This patch restores libata.noacpi support to libata-acpi.c.
There are broken optional control methods for ATA controller devices in the
real world. The libata.noacpi has been used for a long time as a
workaround to deal with issues caused by the broken ASL codes.
1. The "noacpi" option is introduced by the following commit:
commit 11ef697b37
Date: Thu, 28 Sep 2006 11:29:01 -0700
Subject: libata: ACPI and _GTF support
2. The "noacpi" option is renamed to "libata_noacpi" by the following
commit:
commit d7d0dad62a
Date: Wed, 28 Mar 2007 01:57:37 -0400
Subject: [libata] Disable ACPI by default; fix namespace problems
3. Some of its logics are changed over time - becomes relying on the
"acpi_handle" bound to the ATA devices since this commit:
commit fafbae87db
Date: Tue, 15 May 2007 03:28:16 +0900
Subject: libata-acpi: implement ata_acpi_associate()
4. The option is deleted by the following commit:
commit 30dcf76acc
Date: Mon, 25 Jun 2012 16:13:04 +0800
Subject: libata: migrate ACPI code over to new bindings
But the libata.noacpi setup is still left in the kernel without codes to
implement it. So the deletion introduces a regression to the Linux.
This patch disables ATA_ACPI support at runtime by stopping acpi binding
on the ATA devices to fix this regression.
This patch is tested by booting a SATA x86-64 kernel or a PATA x86 kernel
with or without "libata.noacpi=1" kernel command line argument.

Since commit 30dcf76acc, ata_ap_acpi_handle will always do a namespace
walk, which requires acquiring an acpi namespace mutex. This made it
impossible to be used when calling path has held a spinlock.
For example, it can occur in the following code path for pata_acpi:
ata_scsi_queuecmd (ap->lock is acquired)
__ata_scsi_queuecmd
ata_scsi_translate
ata_qc_issue
pacpi_qc_issue
ata_acpi_stm
ata_ap_acpi_handle
acpi_get_child
acpi_walk_namespace
acpi_ut_acquire_mutex (acquire mutex while holding lock)
This caused scheduling while atomic bug, as reported in bug #56781.
Actually, ata_ap_acpi_handle doesn't have to walk the namespace every
time it is called, it can simply return the bound acpi handle on the
corresponding SCSI host. The reason previously it is not done this way
is, ata_ap_acpi_handle is used in the binding function
ata_acpi_bind_host by ata_acpi_gtm when the handle is not bound to the
SCSI host yet. Since we already have the ATA port's handle in its
binding function, we can simply use it instead of calling
ata_ap_acpi_handle there. So introduce a new function __ata_acpi_gtm,
where it will receive an acpi handle param in addition to the ATA port
which is solely used for debug statement. With this change, we can make
ata_ap_acpi_handle simply return the bound handle for SCSI host instead
of walking the acpi namespace now.

Pull fixup for trivial branch from Jiri Kosina:
"Unfortunately I made a mistake when merging into for-linus branch, and
omitted one pre-requisity patch for a few other patches (which have
been Acked by the appropriate maintainers) in the series. Mea culpa
maxima, sorry for that."
The trivial branch added %pSR usage before actually teaching vsnprintf()
about the 'R' part of %pSR. The 'R' causes the symbol translation to do
a "__builtin_extract_return_addr()" before symbol lookup.
That said, on most architectures __builtin_extract_return_addr() isn't
likely to do anything special, so it probably is not normally
noticeable.
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial:
vsprintf: Add extension %pSR - print_symbol replacement
print_symbol takes a long and converts it to a function
name and offset. %pS does something similar, but doesn't
translate the address via __builtin_extract_return_addr.
%pSR does the translation.
This will enable replacing multiple calls like
printk(...);
printk_symbol(addr);
printk("\n");
with a single non-interleavable in dmesg
printk("... %pSR\n", (void *)addr);
Update documentation too.

- Add fileio support for UNMAP discard (asias)
- Add tcm_vhost hotplug support to work with upstream QEMU
vhost-scsi-pci code (asias + mst)
- Check for aborted sequence in tcm_fc response path (mdr)
- Add initial iscsit_transport support into iscsi-target code (nab)
- Refactor iscsi-target RX PDU logic + export request PDU handling
(nab)
- Refactor iscsi-target TX queue logic + export response PDU creation

- Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)
The biggest changes revolve around iscsi-target refactoring in order
to support the iser-target driver. This includes the conversion of
the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
and allowing transport independent aspects of RX/TX PDU
request/response handling be shared across existing traditional
iscsi-target code, and the new iser-target code.

Pull core timer updates from Ingo Molnar:
"The main changes in this cycle's merge are:
- Implement shadow timekeeper to shorten in kernel reader side
blocking, by Thomas Gleixner.
- Posix timers enhancements by Pavel Emelyanov:
- allocate timer ID per process, so that exact timer ID allocations
can be re-created be checkpoint/restore code.
- debuggability and tooling (/proc/PID/timers, etc.) improvements.
- suspend/resume enhancements by Feng Tang: on certain new Intel Atom
processors (Penwell and Cloverview), there is a feature that the
TSC won't stop in S3 state, so the TSC value won't be reset to 0
after resume. This can be taken advantage of by the generic via
the CLOCK_SOURCE_SUSPEND_NONSTOP flag: instead of using the RTC to
recover/approximate sleep time, the main (and precise) clocksource
can be used.
- Fix /proc/timer_list for 4096 CPUs by Nathan Zimmer: on so many
CPUs the file goes beyond 4MB of size and thus the current
simplistic seqfile approach fails. Convert /proc/timer_list to a
proper seq_file with its own iterator.
- Cleanups and refactorings of the core timekeeping code by John
Stultz.
- International Atomic Clock time is managed by the NTP code
internally currently but not exposed externally. Separate the TAI
code out and add CLOCK_TAI support and TAI support to the hrtimer
and posix-timer code, by John Stultz.
- Add deep idle support enhacement to the broadcast clockevents core
timer code, by Daniel Lezcano: add an opt-in CLOCK_EVT_FEAT_DYNIRQ
clockevents feature (which will be utilized by future clockevents
driver updates), which allows the use of IRQ affinities to avoid
spurious wakeups of idle CPUs - the right CPU with an expiring
timer will be woken.

This patch changes the test_and_*_bit functions to use the
load-acquire/store-release instructions instead of explicit DMB.
Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
We're currently relying on unpredictable behaviour in our testops
(test_and_*_bit), as stxr is unpredictable when the status register and
the source register are the same
This patch changes reallocates the status register so as to bring us back into
the realm of predictable behaviour. Boot tested on an AEMv8 model.

Pull SMP/hotplug changes from Ingo Molnar:
"This is a pretty large, multi-arch series unifying and generalizing
the various disjunct pieces of idle routines that architectures have
historically copied from each other and have grown in random, wildly
inconsistent and sometimes buggy directions:
101 files changed, 455 insertions(+), 1328 deletions(-)
this went through a number of review and test iterations before it was
committed, it was tested on various architectures, was exposed to
linux-next for quite some time - nevertheless it might cause problems
on architectures that don't read the mailing lists and don't regularly
test linux-next.
This cat herding excercise was motivated by the -rt kernel, and was
brought to you by Thomas "the Whip" Gleixner."

Maintenance of a bad-block-list currently defaults to 'enabled'
and is then disabled when it cannot be supported.
This is backwards and causes problem for dm-raid which didn't know
to disable it.
So fix the defaults, and only enabled for v1.x metadata which
explicitly has bad blocks enabled.
The problem with dm-raid has been present since badblock support was
added in v3.1, so this patch is suitable for any -stable from 3.1
onwards.
