2009-04-02vfs: skip I_CLEAR state inodesWu Fengguang3-3/+4
clear_inode() will switch inode state from I_FREEING to I_CLEAR, and do so _outside_ of inode_lock. So any I_FREEING testing is incomplete without a coupled testing of I_CLEAR. So add I_CLEAR tests to drop_pagecache_sb(), generic_sync_sb_inodes() and add_dquot_ref(). Masayoshi MIZUMA discovered the bug in drop_pagecache_sb() and Jan Kara reminds fixing the other two cases. Masayoshi MIZUMA has a nice panic flow: ===================================================================== [process A] | [process B] | | | prune_icache() | drop_pagecache() | spin_lock(&inode_lock) | drop_pagecache_sb() | inode->i_state |= I_FREEING; | | | spin_unlock(&inode_lock) | V | | | spin_lock(&inode_lock) | V | | | dispose_list() | | | list_del() | | | clear_inode() | | | inode->i_state = I_CLEAR | | | | | V | | | if (inode->i_state & (I_FREEING|I_WILL_FREE)) | | | continue; <==== NOT MATCH | | | | | | (DANGER from here on!

2009-04-02nommu: fix a number of issues with the per-MM VMA patchDavid Howells6-34/+30
Fix a number of issues with the per-MM VMA patch: (1) Make mmap_pages_allocated an atomic_long_t, just in case this is used on a NOMMU system with more than 2G pages. Makes no difference on a 32-bit system. (2) Report vma->vm_pgoff * PAGE_SIZE as a 64-bit value, not a 32-bit value, lest it overflow. (3) Move the allocation of the vm_area_struct slab back for fork.c. (4) Use KMEM_CACHE() for both vm_area_struct and vm_region slabs. (5) Use BUG_ON() rather than if () BUG(). (6) Make the default validate_nommu_regions() a static inline rather than a #define. (7) Make free_page_series()'s objection to pages with a refcount != 1 more informative. (8) Adjust the __put_nommu_region() banner comment to indicate that the semaphore must be held for writing. (9) Limit the number of warnings about munmaps of non-mmapped regions.

2009-04-01efifb: dmi set video typeBrian Maly1-1/+4
The current logic for dmi matching in efifb does not allow efifb to load on all hardware that we can dmi match for. For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a Apple (MacBook) and EFI framebuffer driver will not load (you will have no video). This specific hardware is efi v1.10, so we have UGA and not GOP. Without special bootloader magic (i.e. extra elilo patches for UGA graphics detection) no screen info will be passed to the kernel and as a result efifb will not load. This patch allows the dmi match to happen by moving it to earlier in efifb_init, and sets the video type (in set_system) so that efifb can load when we have a valid dmi match and already know the specifics of the hardware. Without this patch the efifb driver will fail to load in the event screen info is not found and passed in by the bootloader, being that we will never get to look for a dmi match. A primary reason for matching with dmi is because not all bootloaders detect the video info properly. The solution is that in the event of a dmi match, we should set screen_info.orig_video_isVGA. Most bootloaders fail to set screen info on Apple hardware, and this is a big problem for people who use Apple hardware. Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the issue, the dmi match now works, EFI framebuffer now loads and video works.

2009-04-01fbdev: remove cyblafb driverKrzysztof Helt13-2344/+7
A tridentfb driver has all the functionality of the cyblafb driver without the bugs of the latter. Changes to the tridentfb driver: - FBINFO_READS_FAST added to the tridentfb. The cyblafb used a blitter for scrolling which is faster than color expansion on Cyberblade chipsets. The blitter is slower on a discrete Blade3D core. Use the blitter for scrolling in the tridentfb only for integrated Blade3D cores. Now, scrolling speed is about equal for the tridentfb and the cyblafb. - a copyright notice addition is done on request of Jani Monoses (the first author of the tridentfb). Tested on AGP Blade3D card and PCChips M787CLR motherboard: VIA C3 cpu + VT8601 north bridge (aka Cyberblade/i1).

2009-04-01fbdev: update s1d13xxxfb to differ between revisions and production idsKristoffer Ericson2-18/+46
The s1d13xxx chip provides two values of identification value: the Production id (e.g 13506/13505/13806..) and a revision number 0,1,2,3). Together these can help us to differentiate between similiar setups. This patch adds the proper way of grabbing both those values and save them for future reference (in order to decide what functions a card supports, e.g acceleration). We also move away from the concept of all s1d13xxx = s1d13806 when we really support alot more.
