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.

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.

Add suspend/resume support to the i915 driver. Moves some of the initialization into the driver load routine, and fixes up places where we assumed no dev_private existed in some of the cleanup paths.

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.

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.

The clean up procedure now uses platform device "release" callback to handle memory clean up. For this purpose "release" function callback was added to struct tpm_vendor_specific, so hw device driver provider can get called when it is safe to remove all allocated resources. This is supposed to fix a bug in device removal, where device while in receive function (waiting on timeout) was prone to segfault, if the tpm_chip struct was unallocated before the timeout expired (in tpm_remove_hardware).

After analyzing the elements that save_flags/cli/sti/restore_flags were protecting, convert their usages to a global spinlock (the easiest and most obvious next-step). There were some usages of flags being intentionally cached, because the code already knew the state of interrupts. These have been taken into account. This allows us to remove CONFIG_BROKEN_ON_SMP.

Convert the io_req_t members to unsigned int, to allow use on machines with more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc). There was only a couple of places in drivers where a change was needed. I left printk formats alone (there are lots of %04x-style formats in there), mostly to not change the format on the platforms that only have 16-bit io addresses, but also because the padding doesn't really add all that much value most of the time. I found only one sprintf of an address, and upsized the string accordingly (I doubt anyone will have anywhere near INT_MAX as irq value, but at least there's room for it now).
