tty vt: Fix a regression in command line edition

2012-11-22T00:45:32+00:00

The commit 81732c3b2fede049a692e58a7ceabb6d18ffb18c
("Fix line garbage in virtual console on command line edition")
made a regression with some machines: some characters were not erased
after line edition.

This patch adjusts the number of moved characters and the size of the
region to be updated.

TTY: hvc_console, fix port reference count going to zero prematurely

2012-11-14T20:27:29+00:00

Commit bdb498c20040 "TTY: hvc_console, add tty install" took the port
refcounting out of hvc_open()/hvc_close(), but failed to remove the
kref_put() and tty_kref_put() calls in hvc_hangup() that were there to
remove the extra references that hvc_open() had taken.

The result was that doing a vhangup() when the current terminal was
a hvc_console, then closing the current terminal, would end up calling
destroy_hvc_struct() and making the port disappear entirely.  This
meant that Fedora 17 systems would boot up but then not display the
login prompt on the console, and attempts to open /dev/hvc0 would
give a "No such device" error.

This fixes it by removing the extra kref_put() and tty_kref_put() calls.

Revert "serial: omap: fix software flow control"

2012-10-24T18:57:21+00:00

This reverts commit 957ee7270d632245b43f6feb0e70d9a5e9ea6cf6
(serial: omap: fix software flow control).

As Russell has pointed out, that commit isn't fixing
Software Flow Control at all, and it actually makes
it even more broken.

It was agreed to revert this commit and use Russell's
latest UART patches instead.

 "Here are some tty and serial driver fixes for your 3.7-rc1 tree.

  Again, the UABI header file fixes, and a number of build and runtime
  serial driver bugfixes that solve problems people have been reporting
  (the staging driver is a tty driver, hence the fixes coming in through
  this tree.)

  All of these have been in the linux-next tree for a while.

serial/8250_hp300: Missing 8250 register interface conversion bits

2012-10-15T20:26:14+00:00

commit 2655a2c76f80d91da34faa8f4e114d1793435ed3 ("8250: use the 8250
register interface not the legacy one") forgot to fully switch one
instance of struct uart_port to struct uart_8250_port, causing the
following compile failure:

drivers/tty/serial/8250/8250_hp300.c: In function ‘hpdca_init_one’:
drivers/tty/serial/8250/8250_hp300.c:174: error: ‘uart’ undeclared (first use in this function)
drivers/tty/serial/8250/8250_hp300.c:174: error: (Each undeclared identifier is reported only once
drivers/tty/serial/8250/8250_hp300.c:174: error: for each function it appears in.)

This went unnoticed in -next, as CONFIG_HPDCA is not set to y by
allmodconfig.

sh: Fix up more fallout from pointless ARM __iomem churn.

2012-10-15T05:08:48+00:00

It was already pointed out how to fix these cases before the offending
patches were merged, but unsurprisingly, that didn't happen. As this
change is entirely superfluous to begin with, simply shut things up by
casting everything away.
