xilinx_hwicap: remove improper wording in license statement

2008-12-18T17:13:41+00:00

commit 09a35ce00fa6bbb8bd130a828807e237488aa7ea upstream.

GPLv2 doesn't allow additional restrictions to be imposed on any
code, so this wording needs to be removed from these files.

console ASCII glyph 1:1 mapping

2008-12-18T17:13:38+00:00

commit 1c55f18717304100a5f624c923f7cb6511b4116d upstream.

For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font.  This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.

At the moment it affects all chars for which no substitution character
is defined.  In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g.  control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.

I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e.  chars < 128.

The patch limits the mapping as it probably was meant anyway.

unicode table for cp437

2008-12-18T17:13:37+00:00

commit f75bc06e5d00a827d3ec5d57bbb5b73a4adec855 upstream.

There is a major bug in the cp437 to unicode translation table.  Char
0x7c is mapped to U+00a5 which is the Yen sign and wrong.  The right
mapping is U+00a6 (broken bar).

Furthermore, a mapping for U+00b4 (a widely used character) is missing
even though easily possible.

The patch fixes these, as well as it provides a few other useful
mappings.

The changes are as follows:

  0x0f (enhancement) enables a sort of currency symbol
  0x27 (bug) enables a sort of acute accent which is a widely used character
  0x44 (enhancement) enables a sort of icelandic capital letter eth
  0x7c (major bug) corrects mapping
  0xeb (enhancement) enables a sort of icelandic small letter eth
  0xee (enhancement) enables a sort of math 'element of'

Fix platform drivers that crash on suspend/resume

2008-11-20T22:54:44+00:00

commit fe2d5ffc74a1de6a31e9fd65b65cce72d881edf7 upstream.

It turns out that if one registers a struct platform_device, the
platform device code expects that platform_device.device->driver points
to a struct driver inside a struct platform_driver.

This is not the case with the ipmi-si, ipmi-msghandler and ibmaem
drivers, which causes the suspend/resume hook functions to jump off into
nowhere, causing a crash.  Make this assumption hold true for these
three drivers.

ipmi: add MODULE_ALIAS to load ipmi_devintf with ipmi_si

2008-11-07T03:05:37+00:00

commit 6c89161b10f5771ee0b51ada0fce0e8835e72ade upstream

The ipmi_devintf module contains the userspace interface for IPMI devices,
yet will not be loaded automatically with a system interface handler
driver.

Add a MODULE_ALIAS for the "platform:ipmi_si" MODALIAS exported by the
ipmi_si driver, so that userspace knows of the recommendation.

agp: Fix stolen memory counting on G4X.

2008-11-07T03:05:36+00:00

commit 82e14a6215cbc9804ecc35281e973c6c8ce22fe7 upstream

On the GM45, the amount of stolen memory mapped to the GTT was underestimated,
even though we had 508KB more available since the GTT doesn't take from
stolen memory. On the non-GM45 G4X, we overestimated how much stolen was
mapped to the GTT by 4KB, resulting in GPU page faults when that page was
accessed.

This update requires a corresponding update to xf86-video-intel to work
correctly.

hvc_console: Fix free_irq in spinlocked section

2008-10-25T21:32:41+00:00

commit eef2622a9fcfa964073333ea72c7c9cd20ad45e6 upstream

hvc_console: Fix free_irq in spinlocked section

    commit 611e097d7707741a336a0677d9d69bec40f29f3d
    Author: Christian Borntraeger 
    hvc_console: rework setup to replace irq functions with callbacks
    introduced a spinlock recursion problem. The notifier_del is
    called with a lock held, and in turns calls free_irq which then
    complains when manipulating procfs. This fixes it by moving the
    call to the notifier to outside of the locked section.

kgdboc,tty: Fix tty polling search to use name correctly

2008-09-26T15:36:42+00:00

The tty_find_polling_driver() routine did not correctly check the base
part of the tty name.  This can lead to kgdboc selecting an incorrect
driver, as well as accepting a completely invalid tty such as "echo
ffff0 > /sys/module/kgdboc/parameters/kgdboc".
