tty: Fix LED error return

2012-05-14T17:43:24+00:00

3.4-rc introduced a regression when setting the LEDS. We do the right thing
but then return an error code.

vt: Fix deadlock on scroll-lock

2012-05-01T18:01:28+00:00

Fixing the locking accidentally replaced a race in the scroll
lock handling with a deadlock. Turn it back into a race for
now.

The basic problem is that there are two paths into the tty
stop/start helpers. One via the tty layer ^S/^Q handling
where we need to take the kbd_event_lock and one via the
special keyboard handler for fn_hold where we already hold
it. Probably we need to split out into a separate LED lock
but for now just go back to the race as it's a bit close
to release.

printk(): add KERN_CONT where needed in hpet and vt code

2012-04-09T17:30:39+00:00

A prototype for kmsg records instead of a byte-stream buffer revealed
a couple of missing printk(KERN_CONT ...) uses. Subsequent calls produce
one record per printk() call, while all should have ended up in a single
record.

Instead of:
  ACPI: (supports S0 S5)
  ACPI: PCI Interrupt Link [LNKA] (IRQs 5 *10 11)
  hpet0: at MMIO 0xfed00000, IRQs 2 , 8 , 0

It prints:
  ACPI: (supports S0
   S5
  )
  ACPI: PCI Interrupt Link [LNKA] (IRQs
   5
   *10
   11
  )
  hpet0: at MMIO 0xfed00000, IRQs
   2

Remove all #inclusions of asm/system.h

Remove all #inclusions of asm/system.h preparatory to splitting and killing
it.  Performed with the following command:

perl -p -i -e 's!^#\s*include\s*.*\n!!' `grep -Irl '^#\s*include\s*' *`

TTY: Wrong unicode value copied in con_set_unimap()

2012-03-15T20:28:52+00:00

Bugzilla 40012: PIO_UNIMAP bug: error updating Unicode-to-font map
https://bugzilla.kernel.org/show_bug.cgi?id=40012

The unicode font map for the virtual console is a 32x32x64 table which
allocates rows dynamically as entries are added.  The unicode value
increases sequentially and should count all entries even in empty
rows.  The defect is when copying the unicode font map in con_set_unimap(),
the unicode value is not incremented properly.  The wrong unicode value
is entered in the new font map.

vt: NULL dereference in vt_do_kdsk_ioctl()

2012-03-12T17:21:55+00:00

We forgot to set the "key_map" variable here, so it's still NULL.  This
was introduced recently in 079c9534a9 "vt:tackle kbd_table".

TTY: remove re-assignments to tty_driver members

2012-03-08T19:37:58+00:00

All num, magic and owner are set by alloc_tty_driver. No need to
re-set them on each allocation site.

pti driver sets something different to what it passes to
alloc_tty_driver. It is not a bug, since we don't use the lines
parameter in any way. Anyway this is fixed, and now we do the right
thing.

Some of this ventures into selection which is still a complete lost cause. We
are not making it any worse. It's completely busted anyway.
