2005-12-22[SPARC]: introduce a SPARC Kconfig symbolAdrian Bunk
Introduce a Kconfig symbol SPARC that is defined on both the sparc and sparc64 architectures. This symbol makes some dependencies more readable. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-12-19[SPARC]: Fix RTC build failure.Adrian Bunk

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.

2005-12-12[drm] fix radeon aperture issueDave Airlie
Ben noticed that on certain cards we've landed the AGP space on top of the second aperture instead of after it.. Which messes things up a lot on those machines. This just moves the gart further out, a more correct fix is in the works from Ben for after 2.6.15.

2005-12-12[PATCH] ipmi: fix panic generator IDMatt Domsch
The IPMI specifcation says the generator ID is 0x20, but that is for bits 7-1. Bit 0 is set to specify it is a software event. The correct value is 0x41. Without this fix, panic events written into the System Event Log appear to come from an "unknown" generator, rather than from the kernel.

2005-11-30[PATCH] SiS DRM: Fix possible NULL dereferenceEgbert Eich
This fixes a NULL pointer reference in DRM. The SiS driver tries to allocate a big chunk of memory, but the return value is never checked.

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>
2005-11-23drm: move is_pci to the end of the structureDave Airlie

2005-11-22[PATCH] unpaged: ZERO_PAGE in VM_UNPAGEDHugh Dickins
It's strange enough to be looking out for anonymous pages in VM_UNPAGED areas, let's not insert the ZERO_PAGE there - though whether it would matter will depend on what we decide about ZERO_PAGE refcounting. But whereas do_anonymous_page may (exceptionally) be called on a VM_UNPAGED area, do_no_page should never be: just BUG_ON.

2005-11-09Fix AGP compile on non-x86 architecturesLinus Torvalds
AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i spurely an x86'ism. The proper AGP mapping flusher that should be used is "flush_agp_mappings()", which on x86 obviously happens to do a global TLB flush.
