Don't emit warnings on 64 bit platforms from min(). sizeof() on those is not uint, neither 2 pointers difference, cast it to uint by min_t in both cases.

2008-02-07mga_dma: return 'err' not just zero from mga_do_cleanup_dma()Jesper Juhl
While reading some code I stumbled across the use of 'err' in drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small problem. The variable is only used inside #if __OS_HAS_AGP which is fine, but all that ever happens is an assignment to the variable - it is never actually used for anything. The variable is nicely initialized to zero which is also what the return statement at the end of function returns (always at the moment). It looks to me like that function should be returning 'err' instead of always just returning 0. Here's a patch to do that.

2008-02-07drm: Fix ioc32 compat layerIan Romanick
Previously any ioctls that weren't explicitly listed in the compat ioctl table would fail with ENOTTY. If the incoming ioctl number is outside the range of the table, assume that it Just Works, and pass it off to drm_ioctl. This make the fence related ioctls work on 64-bit PowerPC.

2008-02-07drm: fd.o bug #11895: Only add the AGP base to map offset if the caller didn't.Eric Anholt

2008-02-07i915: add suspend/resume supportJesse Barnes

2008-02-06Fix IXANY and restart after signal (e.g. ctrl-C) in n_tty line disciplineJoe Peterson
Fix two N_TTY line discipline issues related to resuming a stopped TTY (typically done with ctrl-S): 1) Fix handling of character that resumes a stopped TTY (with IXANY) With "stty ixany", the TTY line discipline would lose the first character after the stop, so typing, for example, "hi^Sthere" resulted in "hihere" (the 't' would cause the resume after ^S, but it would then be thrown away rather than processed as an input character). This was inconsistent with the behavior of other Unix systems. 2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs With "stty -ixany" (often the default), interrupt signals were ignored in a stopped TTY until the TTY was resumed with the start char (typically ctrl-Q), which was inconsistent with the behavior of other Unix systems.

2008-02-06tty: enable the echoing of ^C in the N_TTY disciplineJoe Peterson
Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g. ctrl-C will appear as "^C" if stty echoctl is set and ctrl-C is set as INTR). Linux seems to be the only unix-like OS (recently I've verified this on Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really miss this as a good visual confirmation of the interrupt of a program in the console or xterm. I remember this fondly from many Unixs I've used over the years as well. Bringing this to Linux also seems like a good way to make it yet more compliant with standard unix-like behavior.
