After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Since serial devices are powered down when not in use and some of those
devices cannot be accessed when powered down, we need to enable power
around calls to get_mcrtl() when dumping port state via uart_line_info().
This resolves hangs observed on some machines while reading serial device
registers when a port is powered off.

The patch below works around a minor bug found in the UART of the remote
management card used in many HP ia64 and parisc servers (aka the Diva
UARTs). The problem is that the UART does not reassert the THRE interrupt
if it has been previously cleared and the IIR THRI bit is re-enabled. This
can produce a very annoying failure mode when used as a serial console,
allowing a boot/reboot to hang indefinitely until an RX interrupt kicks it
into working again (ie. an unattended reboot could stall).
To solve this problem, a backup timer is introduced that runs alongside the
standard interrupt driven mechanism. This timer wakes up periodically,
checks for a hang condition and gets characters moving again. This backup
mechanism is only enabled if the UART is detected as having this problem,
so systems without these UARTs will have no additional overhead.
This version of the patch incorporates previous comments from Pavel and
removes races in the bug detection code. The test is now done before the
irq linking to prevent races with interrupt handler clearing the THRE
interrupt. Short delays and syncs are also added to ensure the device is
able to update register state before the result is tested.
Aristeu says:
this was tested on the following HP machines and solved the problem:
rx2600, rx2620, rx1600 and rx1620s.
hpa says:
I have seen this same bug in soft UART IP from "a major vendor."

This can be used for serial ports that are connected to an
OF platform bus but are not autodetected by the lecacy
serial support.
It will automatically take over devices that come from the
legacy serial detection, which usually is only one device.
In some cases, rtas may be set up to use the serial port
in the firmware, which allows easier debugging before probing
the serial ports. In this case, the "used-by-rtas" property
must be set by the firmware. This patch also adds code to the
legacy serial driver to check for this.

If RTS interrupt is caused by RTS senzing logic inside i.MX UART module the
IRQ type cannot be set.
It applies only for interrupts going through GPIO layer. The problem has
been noticed by Konstantin Kletschke some time ago.
No IRQF_TRIGGER set_type function for IRQ 26 (MPU)
I would not change type to fixed 0, because it could be possible to use
different GPIO MX1 pin for RTS in the theory. On the other hand it is only
for documentation purposes now, because RTS read code would have to be
adjusted in such case.

The Atmel AT91 and AVR32 processor architectures share many of the same
peripherals. The PDC (Peripheral Data Controller) registers are also
implemented within in a number of the on-chip peripherals (eg, USART,
MMC, SPI, SSC, etc).
In a attempt not to duplicate the register definitions in each
peripheral, or in each architecture, the at91_pdc.h header in
asm-arm/arch-at91 and asm-avr32/arch-at32ap has been replaced with
linux/atmel_pdc.h.
The definitions have also been renamed from AT91_PDC_* to ATMEL_PDC_*,
and the drivers updated accordingly.

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the
current kernel. Current patch fixes it, as well as other inconsistencies
expressed, that do not permit targets from working properly:
- Updated dts with a chosen node with interrupt controller,
- fixed messed device IDs among CPM2 SoC devices,
- corrected odd header name and fixed type in defines,
- Added 82xx subdir to the powerpc/platforms Makefile, missed during
initial commit,
- new solely-powerpc header file for 8260 family (was using one from
arch/ppc, this one cleaned up from the extra stuff), in fact for now
a placeholder to get the board-specific includes for stuff not yet
capable to live with devicetree peeks only
- Fixed couple of misprints in reference mpc8272 dts.

This adds initial support to 8250-pci for the Korenix Jetcard PCI serial
cards. The JC12xx cards are standard RS232-based serial cards utilising
the Oxford 16C950 device.
The JC14xx are RS422/RS485-based cards, but in order for these to be
supported natively, we will need additional tweaks to the 8250 layers so
we can specify some values for the 950's registers. Hence, these two
entries are commented out.

This is the grungy swap all the occurrences in the right places patch that
goes with the updates. At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs
If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.
If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)
Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra

The pl010 primecell documentation specifies that an error indicated via RSR
should be cleared by a write to ECR. We didn't do this, which was causing
errors to be re-reported on every call to pl010_rx_chars().

This a set of fixes mostly to make the driver actually work:
1. Actually select the line for setting parameters and receiver
disable/enable.
2. Select the line for receive and transmit interrupt handling correctly.
3. Report the transmitter empty state correctly.
4. Set the I/O type of ports correctly.
5. Perform polled transmission correctly.
6. Don't fix the console line at ttyS3.
7. Magic SysRq support.
8. Various small bits here and there.

Pass struct dev pointer to dma_cache_sync()
dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.

This is on our "Envoy" boxes which we have, according to the documentation, an
"Exar ST16C554/554D Quad UART with 16-byte Fifo's". The box also has two
other "on-board" serial ports and a modem chip.
The two on-board serial UARTs were being detected along with the first two
Exar UARTs. The last two Exar UARTs were not showing up and neither was the
modem.
This patch was the only way I could the kernel to see beyond the standard four
serial ports and get all four of the Exar UARTs to show up.
