2006-09-10[AGPGART] Rework AGPv3 modesetting fallback.Dave Jones
Sometimes the logic to handle AGPx8->AGPx4 fallback failed, as can be seen in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=197346 The failures occured if the bridge was in AGPx8 mode, but the user hadn't specified a mode in their X config. We weren't setting the mode to the highest mode capable by the video card+bridge (as we do in the AGPv2 case), which was leading to all kinds of mayhem including us believing that after falling back from AGPx8, that we couldn't do x4 mode (which is disastrous in AGPv3, as those are the only two modes possible).

2006-09-01[PATCH] IPMI: fix occasional oops on module unloadCorey Minyard
Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI driver would occasionally result in Oopses. He tracked that down to a variable that wasn't always initialized properly in some situations. This patch initializes that variable. Olaf sent a patch that kzalloc-ed the data, but this structure is large enough that I would perfer to not do that. Thanks Olaf!

2006-08-27[PATCH] Fix tty layer DoS and comment relevant codeAlan Cox
Unlike the other tty comment patch this one has code changes. Specifically it limits the queue size for a tty to 64K characters (128Kbytes) worst case even if the tty is ignoring tty->throttle. This is because certain drivers don't honour the throttle value correctly, although it is a useful safeguard anyway.

2006-08-27[PATCH] vcsa attribute bits -> ioctl(VT_GETHIFONTMASK)Samuel Thibault
When reading /dev/vcsa while a font with more than 256 characters is loaded, one of the attribute bits records the 9th bit of the character. But depending on the console driver (vgacon or fbcon for instance), that's bit 3 or bit 0. And there is no way for userland to know that, thus no way for userland to safely grab the screen content. So here is a (tested) patch: Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC text (vc_hi_font_mask field of the vc_data structure).

2006-08-27[PATCH] char/moxa.c: fix endianess and multiple-card issuesDirk Eibach
While testing Moxa C218T/PCI on PowerPC 405EP I found that loading firmware using the linux kernel driver fails because calculation of the checksum is not endianess independent in the original code. After I fixed this I found that uploading firmware in a system with multiple cards causes a kernel oops. I had a look in the recent moxa sources and found that they do some kind of locking there. Applying this lock fixed the problem. Alan sayeth: Checksum changes are clearly correct. Other changes is an improvement but not I think enough to handle malicious firmware attacks. That said such an attacker has CAP_SYS_RAWIO anyway so that part is irrelevant except for neatness.

2006-08-06[PATCH] pSeries: hvsi char driver janitorial cleanupLinas Vepstas
A set of tty line discipline cleanup patches were introduced before the dawn of time, in kernel version 2.4.21. This patch performs that cleanup for the hvsi driver. The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was originally written by Hollis Blanchard, who has delegated maintainership to me. So this my first and maybe only patch in this official new role, because this driver is otherwise bug-free :-) Alan: "Actually its also a bug fix, tty->ldisc should be locked by refcounting and the helpers do this for you."

Ive never tested other pins, and theyre all multiplexed with other functions, some of which may be in use on my soekris 4801, so I dont know what testing should yield. - +EXPORT_SYMBOL(scx200_access); This exposes the driver's vtable, which another driver can use along with #include <linux/nsc_gpio.h>, to manipulate a gpio-pin.

2006-07-10[PATCH] snsc: switch from force_sig to kill_procChristoph Hellwig
Currently the snsc driver uses force_sig to send init a SIGPWR when the system overheats. This patch switches it to kill_proc instead which has the following advantages: (1) gets rid of one of the last remaining tasklist_lock users in modular code (2) simplifies the snsc code significantly The downside is that an init implementation could in theory block SIGPWR and it would not get delivered. The sysvinit code used by all major distributions doesn't do this and blocking this signal in init would be a rather stupid thing to do.

Code compiles and runs, exhibits a lesser error than previously.
