Now that we have ACPI-based SMBus controller drivers, and we will start
telling users to use them instead of native drivers when I/O resources
conflict, I think it would be good to clearly mark ACPI drivers as such
in Kconfig.
This is exactly the same as we just did for hwmon drivers.

request_mem_region should be used when ioremap is used subsequently.
release_region is then correspondingly replaced by release_mem_region.

Make the I/O faster, mainly by using combined SMBus transactions when
possible. While the TSL2550 datasheet doesn't say the device supports
them, they seem to work just fine in practice, and a combined
transaction is faster than two simple transactions in many cases and
always more reliable.
A side effect is to suppress the delays between SMBus writes and
reads. The datasheet doesn't say they are needed and things work just
fine for me without them.
I also couldn't see any reason for the delay between reading the two
channels. Nor for the loop to get a reading in the first place. The
400 ms delay between samples only matters at chip power-up, after that
the chip always hold the previously sampled value so we never get to
wait.
All these changes make reading the lux value much faster and cheaper.

Commit ac89a9174 ("pty: don't limit the writes to 'pty_space()' inside
'pty_write()'") removed the pty_space() checking, in order to let the
regular tty buffer code limit the buffering itself.
That was all good, but as a subtle side effect it meant that we'd be
doing a tty_wakeup() even in the case where the buffers were all filled
up, and didn't actually make any progress on the write.
Which sounds innocuous, but it interacts very badly with the ppp_async
code, which has an infinite loop in ppp_async_push() that tries to push
out data to the tty. When we call tty_wakeup(), that loop ends up
thinking that progress was made (see the subtle interactions between
XMIT_WAKEUP and 'tty_stuffed' for details). End result: one unhappy ppp
user.
Fixed by noticing when tty_insert_flip_string() didn't actually do
anything, and then not doing any more processing (including, very much
not calling tty_wakeup()).

Recent enhancement of rb-tree based lookup exposed a bug with the lookup
mechanism in the reserve_memtype() which ensures that there are no conflicting
memtype requests for the memory range.
memtype_rb_search() returns an entry which has a start address <= new start
address. And from here we traverse the linear linked list to check if there
any conflicts with the existing mappings. As the rbtree is based on the
start address of the memory range, it is quite possible that we have several
overlapped mappings whose start address is much less than new requested start
but the end is >= new requested end. This results in conflicting memtype
mappings.
Same bug exists with the old code which uses cached_entry from where
we traverse the linear linked list. But the new rb-tree code exposes this
bug fairly easily.
For now, don't use the memtype_rb_search() and always start the search from
the head of linear linked list in reserve_memtype(). Linear linked list
for most of the systems grow's to few 10's of entries(as we track memory type
of RAM pages using struct page). So we should be ok for now.
We still retain the rbtree and use it to speed up free_memtype() which
doesn't have the same bug(as we know what exactly we are searching for
in free_memtype).
Also use list_for_each_entry_from() in free_memtype() so that we start
the search from rb-tree lookup result.

On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects
PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports:
ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2
ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11)
ata4.00: configured for PIO0
For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM
reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up
allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up
using PIO0.
Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless
of what cable type is used, let's make sure we don't filter out these modes
regardless of what wacky settings the BIOS is using.

sata_promise's reset code has deviated quite a bit from
the Promise reference driver's, and it has been observed
to fail to recover from errors in some cases.
This patch thus updates the reset code to more closely
match the reference driver:
- soft reset (pdc_reset_port):
* wait for ATA engine to not be in packet command mode
(2nd gen only)
* write reset bit in PDC_CTLSTAT before the first read
in the loop
* for 2nd gen SATA follow up with FPDMA reset and clearing
error status registers
- hard reset (pdc_sata_hardreset):
* wait for ATA engine to not be in packet command mode
(2nd gen only)
* reset ATA engine via the PCI control register
* Tejun's change to use non-waiting hardreset + follow-up SRST
I'm not changing the hotplug mask bits since they are taken care
of by sata_promise's ->freeze() and ->thaw() operations. And I'm
not writing the PMP port # because that's always zero (for now).
Tested here on various controllers. In particular, one disk
which used to timeout and fail to recover from certain hdparm
and smartmonctl commands now works nicely.

1st generation Promise SATA chips are prone to generating spurious
hotplug events which can disrupt normal operation. This has been
observed on 20376 and 20378 chips. This patch thus disables hotplug
support on 1st gen chips while leaving it enabled for 2nd gen chips.
The pdc_sata_hotplug_offset() function becomes redundant so it is
removed.

after the port is frozen. This is necessary to guarantee that TF
registers are accessed after the DMA engine is shutdown after an
error. However, this triggers WARN_ON_ONCE() check in
ata_qc_complete() spuriously. Move WARN_ON_ONCE() downwards such that
failing commands while frozen doesn't trigger it.

Commit a5bfc4714b3f01365aef89a92673f2ceb1ccf246 dropped explicit
pci_intx() manipulation from ahci because it seemed unnecessary and
ahci doesn't seem to be the right place to be tweaking it if it were.
This was largely okay but there are exceptions. There was one on an
embedded platform which was fixed via firmware and now bko#14124
reports it on a HP DL320.
http://bugzilla.kernel.org/show_bug.cgi?id=14124
I still think this isn't something libata drivers should be caring
about (the only ones which are calling pci_intx() explicitly are
libata ones and one other driver) but for now reverting the change
seems to be the right thing to do.

For direct function pointers (like what mcount provides) PowerPC64

This patch converts all prints of functions retrieved through mcount
to use the %ps format from the %pf.
Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

On PowerPC64 function pointers do not point directly at the functions,
but instead point to pointers to the functions. The output of %pF expects
to point to a pointer to the function, whereas %pS will show the function
itself.
mcount returns the direct pointer to the function and not the pointer to
the pointer. Thus %pS must be used to show this. The function tracer
requires printing of the functions without offsets and uses the %pf
instead.
%pF produces run_local_timers+0x4/0x1f
%pf produces just run_local_timers
For PowerPC64, we need to use the direct pointer, and we only have
%pS which will produce .run_local_timers+0x4/0x1f
This patch creates a %ps that matches the %pf as %pS matches %pF.

Todo: Nothing ever detects CPU_BCM6338 but the code tests for it anyway.

There is a bunch of platform device registration in
arch/mips/cavium-octeon/setup.c. We move it to its own file in
preparation for adding more platform devices.

The code after the vmalloc_fault: label in do_page_fault() modifies
user page tables, this is not correct for 64-bit kernels.
For 64-bit kernels we should go straight to the no_context handler
skipping vmalloc_fault.

By combining swapper_pg_dir and module_pg_dir, several if conditions
can be eliminated from the tlb exception handler. The reason they
can be combined is that, the effective virtual address of vmalloc
returned is at the bottom, and of module_alloc returned is at the
top. It also fixes the bug in vmalloc(), which happens when its
return address is not covered by the first pgd.

loops_per_jiffy depends on coreclk speed; preset it instead of
letting the kernel waste precious microseconds trying to approximate it.
