To fix a nasty bug in ldisc hup vs. reinit we need to wait infinitely
long for ldisc to be gone. So here we add a parameter to
tty_ldisc_wait_idle to allow that.
This is only a preparation for the real fix which is done in the
following patches.

The crisv10.c and the atmel_serial.c serial drivers intepret the fields of the
serial_rs485 structure in a different way.
In particular, crisv10.c uses SER_RS485_RTS_AFTER_SEND and
SER_RS485_RTS_ON_SEND for the voltage of the RTS pin; atmel_serial.c,
instead, uses these values to know if a delay must be set before and
after sending. This patch makes the usage of these variables consistent
across all drivers and fixes the Documentation as well.
From now on, SER_RS485_RTS_AFTER_SEND and SER_RS485_RTS_ON_SEND will be
used to set the voltage of the RTS pin (as in the crisv10.c driver); the
delay will be understood by looking only at the value of
delay_rts_before_send and delay_rts_after_send.

Changing UART mode PIO->DMA->PIO->DMA like below, pch_uart driver can't get
DMA channel resource.
setserial /dev/ttyPCH0 ^low_latency
setserial /dev/ttyPCH0 low_latency
CAUSE:
Changing mode using setserial command, ".startup" function which gets DMA
channel is called before ".verify_port" function which sets
dma-flag(use_dma/use_dma_flag) as 1.
PIO->DMA
.startup: Since dma-flag is 0, DMA channel is not requested.
.verify_port: dma-flag is set as 1.
.shutdown: N/A
DMA->PIO
.startup: Since dma-flag is 1, DMA channel is requested.
.verify_port: dma-flag is set as 0.
.shutdown: Since dma-flag is 0, DMA channel is not released.
This means DMA channel resource leak occurs.
Next time, this driver can't get DMA channel resource forever.
MODIFICATION:
Currently, when release DMA channel resource, this driver checks dma-flag.
However, this specification occurs the above issue.
This driver must check whether dma_request_channel is executed or not.
The values are saved in private data variable "chan_tx/chan_tx".
These variables mean if the value is NULL, DMA channel is not requested,
if not NULL, DMA channel is requested.
This patch fixes the issue.

On Tegra UARTs (except UART1), the DTR / DCD / DSR lines are not
externally accessible. Instead, the DTR line internally appears to be
looped back to be the input to the DCD and DSR lines. The net effect
of this is that when we drop DTR (like when we suspend), we'll see DCD
drop too. ...and when we see DCD drop, we treat that as a hangup.
In order to prevent this hangup from occurring at every sleep, we need
to force DTR to remain high on Tegra UARTs.
This patch uses the mcr_mask / mcr_force fields, which were originally
added for the kludge ALPHA_KLUDGE_MCR. Using these fields does not
prevent us from removing ALPHA_KLUDGE_MCR--we can just remove the "if"
tests I have added and always init mcr_mask / mcr_force from the
serial8250_config.
NOTE: If we have people that are using UARTA on a Tegra and need to
control DTR, we'll need to either add a separate port type for UARTA
or we'll need to add some tegra-specific code to detect whether the
DTR needs to be left high.

Reading from the DCC grabs a character from the buffer and
clears the status bit. Since this is a context-changing
operation, instructions following the character read that rely on
the status bit being accurate need to be synchronized with an
ISB.
In this case, the status bit check needs to execute after the
character read otherwise we run the risk of reading the character
and checking the status bit before the read can clear the status
bit in the first place. When this happens, the user will see the
same character they typed twice, instead of once.
Add an ISB after the read and the write, so that the status check
is synchronized with the read/write operations.

Mountpoint crossing is similar to following procfs symlinks - we do
not get ->d_revalidate() called for dentry we have arrived at, with
unpleasant consequences for NFS4.
Simple way to reproduce the problem in mainline:
cat >/tmp/a.c <<'EOF'
#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
main()
{
struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1};
if (fcntl(0, F_SETLK, &fl))
perror("setlk");
}
EOF
cc /tmp/a.c -o /tmp/test
then on nfs4:
mount --bind file1 file2
/tmp/test < file1 # ok
/tmp/test < file2 # spews "setlk: No locks available"...
What happens is the missing call of ->d_revalidate() after mountpoint
crossing and that's where NFS4 would issue OPEN request to server.
The fix is simple - treat mountpoint crossing the same way we deal with
following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.
