2006-01-08[PATCH] ARM Netwinder watchdog wdt977 updateWoody Suwalski
Cleanup for the ARM-only watchdog driver wdt977. This is probably the last update, since we want to merge with w83977f_wdt. Jose Goncalves has ported this driver to i386, so probably we can iron out configuration differences.

2006-01-06[PATCH] pcmcia: unify attach, EVENT_CARD_INSERTION handlers into one probe ↵Dominik Brodowski
callback Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified probe() callback. As all in-kernel drivers are changed to this new callback, there will be no temporary backwards-compatibility. Inside a probe() function, each driver _must_ set struct pcmcia_device *p_dev->instance and instance->handle correctly. With these patches, the basic driver interface for 16-bit PCMCIA drivers now has the classic four callbacks known also from other buses: int (*probe) (struct pcmcia_device *dev); void (*remove) (struct pcmcia_device *dev); int (*suspend) (struct pcmcia_device *dev); int (*resume) (struct pcmcia_device *dev); Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2005-12-29Revert radeon AGP aperture offset changesLinus Torvalds
This reverts the series of commits 67dbb4ea33731415fe09c62149a34f472719ac1d 281ab031a8c9e5b593142eb4ec59a87faae8676a 47807ce381acc34a7ffee2b42e35e96c0f322e52 that changed the GART VM start offset. It fixed some machines, but seems to continually interact badly with some X versions. Quoth Ben Herrenschmidt: "So I think at this point, the best is that we keep the old bogus code that at least is consistent with the bug in the server. I'm working on a big patch to X that reworks the memory map stuff completely and fixes those issues on the server side, I'll do a DRM patch matching this X fix as well so that the memory map is only ever set in one place and with what I hope is a correct algorithm..."

2005-12-27[PATCH] Fix more radeon GART start calculation casesBenjamin Herrenschmidt
As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the recent GART aperture start reconfiguration causes problems on some setups. What I _think_ might be happening is that the X server is also trying to muck around with the card memory map and is forcing it back into a wrong setting that also happens to no longer match what the DRM wants to do and blows up. There are bugs all over the place in that code (and still some bugs in the DRM as well anyway). This patch attempts to avoid that by using the largest of the 2 values, which I think will cause it to behave as it used to for you and will still fix the problem with machines that have an aperture size smaller than the video memory.

2005-12-18[PATCH] radeon drm: fix compilation breakage with gcc 2.95.3Jean Delvare
Fix a typo which breaks radeon drm compilation with gcc 2.95.3. The offending line was added back in 2.6.11-rc3, but was harmless back then. A recent addition nearby changed it into a compilation breaker: commit 281ab031a8c9e5b593142eb4ec59a87faae8676a. The doubled semi-colon ends up being an empty instruction, and the variable declaration thus ends up being in the middle of "code".

2005-12-15[PATCH] radeon drm: fix agp aperture map offsetBenjamin Herrenschmidt
This finally fixes the radeon memory mapping bug that was incorrectly fixed by the previous patch. This time, we use the actual vram size as the size to calculate how far to move the AGP aperture from the framebuffer in card's memory space. If there are still issues with this patch, they are due to bugs in the X driver that I'm working on fixing too. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Mark M.

2005-12-15[PATCH] IPMI oops fixPaolo Galtieri
While doing some testing I discovered that if the BIOS on a board does not properly setup the DMI information it leads to a panic in the IPMI code. The panic is due to dereferencing a pointer which is not initialized. The pointer is initialized in port_setup() and/or mem_setup() and used in init_one_smi() and cleanup_one_si(), however if either port_setup() or mem_setup() return ENODEV the pointer does not get initialized.

2005-11-28mm: re-architect the VM_UNPAGED logicLinus Torvalds
This replaces the (in my opinion horrible) VM_UNMAPPED logic with very explicit support for a "remapped page range" aka VM_PFNMAP. It allows a VM area to contain an arbitrary range of page table entries that the VM never touches, and never considers to be normal pages. Any user of "remap_pfn_range()" automatically gets this new functionality, and doesn't even have to mark the pages reserved or indeed mark them any other way. It just works. As a side effect, doing mmap() on /dev/mem works for arbitrary ranges. Sparc update from David in the next commit. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-11-24drm: fix quiescent lockingDave Airlie
A fix for a locking bug which is triggered when a client tries to lock with flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock. From: Thomas Hellstrom Signed-off-by: Dave Airlie <airlied@linux.ie>
