While trying to work around spurious detection retries for
non-existent devices on slave links, commit
816ab89782 incorrectly added link
offline check logic before ata_eh_thaw() was called. This means that
if an occupied link goes down briefly at the time that offline check
was performed, device class will be cleared to ATA_DEV_NONE and libata
wouldn't retry thus failing detection of the device.
The offline check should be done after the port is thawed together
with online check so that such link glitches can be detected by the
interrupt handler and handled properly.

Curiously, Aspire 3810T issues many SATA feature enable commands via
_GTF, of which one is invalid and another is not supported by the
drive. In the process, it also enables FPDMA non-zero offset.
However, the feature also needs to be supported and enabled from the
controller and it's wrong to enable it from _GTF unless the controller
can do it by default.
Currently, this ends up enabling FPDMA non-zero offset only on the
drive side leading to NCQ command failures and eventual disabling of
NCQ. This patch makes libata filter out FPDMA non-zero offset enable
for the machine.
This was reported by Marcus Meissner in bnc#522790.

Update the AHCI driver to display all of the HBA capabilities defined in the
AHCI 1.3 specification. Some of these are in a new CAP2 (HBA Capabilities
Extended) register which is only defined on AHCI 1.2 or later. The spec says
that undefined registers should always return 0 on read, but to be safe we
assume a value of 0 unless the controller reports AHCI version 1.2 or later.
The value can also be retrieved through sysfs as with the existing capability
field.
For example, on an Intel Ibex Peak (PCH) controller:
ahci 0000:00:1f.2: flags: 64bit ncq sntf stag pm led clo pmp pio slum part ems
sxs apst
We don't do anything special with the new flags yet.
Also, change the code that displays the flags to use the same bit enumerations
that are used to control actual operation.

A couple of people have hit the WARN_ON() in drivers/char/tty_io.c,
tty_open() that is unhappy about seeing the tty line discipline go away
during the tty hangup. See for example
http://bugzilla.kernel.org/show_bug.cgi?id=14255
and the reason is that we do the tty_ldisc_halt() outside the
ldisc_mutex in order to be able to flush the scheduled work without a
deadlock with vhangup_work.
However, it turns out that we can solve this particular case by
- using "cancel_delayed_work_sync()" in tty_ldisc_halt(), which waits
for just the particular work, rather than synchronizing with any
random outstanding pending work.
This won't deadlock, since the buf.work we synchronize with doesn't
care about the ldisc_mutex, it just flushes the tty ldisc buffers.
- realize that for this particular case, we don't need to wait for any
hangup work, because we are inside the hangup codepaths ourselves.
so as a result we can just drop the flush_scheduled_work() entirely, and
then move the tty_ldisc_halt() call to inside the mutex. That way we
never expose the partially torn down ldisc state to tty_open(), and hold
the ldisc_mutex over the whole sequence.

I was recently lucky enough to get a 64-CPU system. The processors
actually have T-states, so my kernel log ends up with 64 lines like:
ACPI: Processor [CPU0] (supports xx throttling states)
This is pretty useless clutter because
- this info is already available after boot from
/proc/acpi/processor/CPUnn/throttling
- there's also an ACPI_DEBUG_PRINT() in processor_throttling.c that
gives the same info on boot for anyone who *really* cares.
So just delete the code that prints the throttling states in
processor_core.c.

The function sfi_map_memory/sfi_unmap_memory uses
early_ioremap/early_iounmap respectively, which refers to a __init

sfi_verify_table. Since the references are valid, so use __ref to get rid
of the warnings.
