9b02605826 sparc64: Kill bogus TPC/address truncation during 32-bit faults.
This builds upon eeabac7386
("sparc64: Validate kernel generated fault addresses on sparc64.")

Upon further consideration, we actually should never see any
fault addresses for 32-bit tasks with the upper 32-bits set.

If it does every happen, by definition it's a bug.  Whatever
context created that fault would only have that fault satisfied
if we used the full 64-bit address.  If we truncate it, we'll
always fault the wrong address and we'll always loop faulting
forever.

So catch such conditions and mark them as errors always.  Log
the error and fail the fault.

1a5645bc90 connector: create connector workqueue only while needed once
The netlink connector uses its own workqueue to relay the datas sent
from userspace to the appropriate callback.  If you launch the test
from Documentation/connector and change it a bit to send a high flow
of data, you will see thousands of events coming to the "cqueue"
workqueue by looking at the workqueue tracer.

This flow of events can be sent very quickly. So, to not encumber the
kevent workqueue and delay other jobs, the "cqueue" workqueue should
remain.

But this workqueue is pointless most of the time, it will always be
created (assuming you have built it of course) although only
developpers with specific needs will use it.

So avoid this "most of the time useless task", this patch proposes to
create this workqueue only when needed once.  The first jobs to be
sent to connector callbacks will be sent to kevent while the "cqueue"
thread creation will be scheduled to kevent too.

The following jobs will continue to be scheduled to keventd until the
cqueue workqueue is created, and then the rest of the jobs will
continue to perform as usual, through this dedicated workqueue.

Each time I tested this patch, only the first event was sent to
keventd, the rest has been sent to cqueue which have been created
quickly.

Also, this patch fixes some trailing whitespaces on the connector files.

eeabac7386 sparc64: Validate kernel generated fault addresses on sparc64.
In order to handle all of the cases of address calculation overflow
properly, we run sparc 32-bit processes in "address masking" mode
when running on a 64-bit kernel.

Address masking mode zeros out the top 32-bits of the address
calculated for every load and store instruction.

However, when we're in privileged mode we have to run with that
address masking mode disabled even when accessing userspace from
the kernel.

To "simulate" the address masking mode we clear the top-bits by
hand for 32-bit processes in the fault handler.

It is the responsibility of code in the compat layer to properly
zero extend addresses used to access userspace.  If this isn't
followed properly we can get into a fault loop.

Say that the user address is 0xf0000000 but for whatever reason
the kernel code sign extends this to 64-bit, and then the kernel
tries to access the result.

In such a case we'll fault on address 0xfffffffff0000000 but the fault
handler will process that fault as if it were to address 0xf0000000.
We'll loop faulting forever because the fault never gets satisfied.

So add a check specifically for this case, when the kernel is faulting
on a user address access and the addresses don't match up.

This code path is sufficiently slow path, and this bug is sufficiently
painful to diagnose, that this kind of bug check is warranted.

802c64b310 sparc64: On non-Niagara, need to touch NMI watchdog in NOHZ mode.
When we're idling in NOHZ mode, timer interrupts are not running.

Evidence of processing timer interrupts is what the NMI watchdog
uses to determine if the CPU is stuck.

On Niagara, we'll yield the cpu.  This will make the cpu, at
worst, hang out in the hypervisor until an interrupt arrives.
This will prevent the NMI watchdog timer from firing.

However on non-Niagara we just loop executing instructions
which will cause the NMI watchdog to keep firing.  It won't
see timer interrupts happening so it will think the cpu is
stuck.

Fix this by touching the NMI watchdog in the cpu idle loop
on non-Niagara machines.

9062712fa9 libata: implement HORKAGE_1_5_GBPS and apply it to WD My Book
3Gbps is often much more prone to transmission failures.  It's usually
okay to let EH handle speed down after transmission failures but some
WD My Book drives completely shutdown after certain transmission
failures and after it only power cycling can revive them.  Combined
with the fact that external drives often end up with cable assembly
which is longer than usual and more likely to have intervening gender,
this makes these drives very likely to shutdown under certain
configurations virtually rendering them unusable.

This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book
such that 1.5Gbps is forced once the device is identified.

Please take a look at the following bz for related reports.

c2c7a89c5e libata: improve probe failure handling
When link is flaky at high speed, it isn't uncommon for a device to
repeatedly fail probing sequence early after successfully negotiating
high link speed.  This often leads to consecutive hotplug events
without successful probing.

This patch improves libata EH such that it remembers probing trials
and if there have been more than two unsuccessful trials in the past
60 seconds, slows down link speed to 1.5Gbps.

As link speed negotiation is the duty of the PHY layer proper, the
goal of this fallback mechanism is to provide the last resort when
everything else fails, which unfortunately happens not too
infrequently, so no fancy 6->3->1.5 speeding down or highest
successful transmission speed seen kind of logics (yet).

99cf610aa4 libata: clear dev->ering in smarter way
dev->ering used to be cleared together with the rest of ata_device in
ata_dev_init() which is called whenever a probing event occurs.
dev->ering is about to be used to track probing failures so it needs
to remain persistent over multiple porbing events.  This patch
achieves this by doing the following.

* Instead of CLEAR_OFFSET, define CLEAR_BEGIN and CLEAR_END and only
  clear between BEGIN and END.  ering is moved after END.  The split
  of persistent area is to allow hotter items remain at the head.

* ering is explicitly cleared on ata_dev_disable() and when device
  attach succeeds.  So, ering is persistent throug a device's life
  time (unless explicitly cleared of course) and also through periods
  inbetween disablement of an attached device and successful detection
  of the next one.

4462254ac6 sata_mv: Fix chip type for Hightpoint RocketRaid 1740/1742
Fix chip type for the Highpoint RocketRAID 1740 and 1742 PCI cards.
These really do have Marvell 6042 chips on them, rather than the 5081 chip.

Confirmed by multiple (two) users (for the 1740), and by examining
the product photographs from Highpoint's web site.

41137aa61c [libata] sata_sil: Fix compilation error with libata debugging enabled
I tried compiling 2.6.29-rc1 and 2.6.29-rc3 with libata debugging enabled
and got the following error:

  CC [M]  drivers/ata/sata_sil.o
drivers/ata/sata_sil.c: In function 'sil_fill_sg':
drivers/ata/sata_sil.c:327: error: 'pi' undeclared (first use in this function)
drivers/ata/sata_sil.c:327: error: (Each undeclared identifier is reported only once
drivers/ata/sata_sil.c:327: error: for each function it appears in.)
make[2]: *** [drivers/ata/sata_sil.o] Error 1
make[1]: *** [drivers/ata] Error 2
make: *** [drivers] Error 2

include/linux/libata.h has the following enabled:

#define ATA_DEBUG
#define ATA_VERBOSE_DEBUG
#define ATA_IRQ_TRAP

This fixes the compilation.
