2007-07-21atmel_lcdfb: Fix STN LCD supportNicolas Ferre
Fixes STN LCD support for the atmel_lcdfb framebuffer driver. This patch is the result of a work from Jan Altenberg and has been tested on a Hitachi SP06Q002 on at91sam9261ek. It adds a Kconfig switch that enables the proper LCD in the board configuration file (STN or TFT). The switch is used in arch/arm/mach-at91/at91sam9261_devices.c & board-sam9261ek.c as an example. This patch includes the "Fix wrong line_length calculation" little one from Jan and Haavard (submitted earlier).

2007-07-21rtc: add support for STK17TA8 chipThomas Hommel
This patch adds support for the Simtek STK17TA8 timekeeping chip. The STK17TA8 is quite similar to the DS1553, but differs in register layout and in various control bits in the registers. I chose to make this a new driver to avoid confusion in the code and to not get lost in #ifdefs.

2007-07-21slob: reduce list scanningMatt Mackall
The version of SLOB in -mm always scans its free list from the beginning, which results in small allocations and free segments clustering at the beginning of the list over time. This causes the average search to scan over a large stretch at the beginning on each allocation. By starting each page search where the last one left off, we evenly distribute the allocations and greatly shorten the average search. Without this patch, kernel compiles on a 1.5G machine take a large amount of system time for list scanning. With this patch, compiles are within a few seconds of performance of a SLAB kernel with no notable change in system time.

2007-07-21coda: remove CODA_STORE/CODA_RELEASE upcallsJan Harkes
This is an variation on the patch sent by Christoph Hellwig which kills file_count abuse by the Coda kernel module by moving the coda_flush functionality into coda_release. However part of reason we were using the coda_flush callback was to allow Coda to pass errors that occur during writeback from the userspace cache manager back to close(). As Al Viro explained on linux-fsdevel, it is impossible to guarantee that such errors can in fact be returned back to the caller. There are many cases where the last reference to a file is not released by the close system call and it is also impossible to pick some close as a 'last-close' and delay it until all other references have been destroyed. The CODA_STORE/CODA_RELEASE upcall combination is clearly a broken design, and it is better to remove it completely.

2007-07-21nommu: vmalloc_32_user()/vm_insert_page() and symbol exports.Paul Mundt
Trying to survive an allmodconfig on a nommu platform results in many screen lengths of module unhappiness. Many of the mmap related things that binfmt_flat hooks in to are never exported despite being global, and there are also missing definitions for vmalloc_32_user() and vm_insert_page(). I've implemented vmalloc_32_user() trying to stick as close to the mm/vmalloc.c implementation as possible, though we don't have any need for VM_USERMAP, so groveling for the VMA can be skipped. vm_insert_page() has been stubbed for now in order to keep the build happy.

2007-07-21Fix swiotlb_sync_single_range()Keir Fraser
If the swiotlb maps a multi-slab region, swiotlb_sync_single_range() can be invoked to sync a sub-region which does not include the first slab. Unfortunately io_tlb_orig_addr[] is only initialised for the first slab, and hence the call to sync_single() will read a garbage orig_addr in this case. This patch fixes the issue by initialising all mapped slabs in io_tlb_orig_addr[]. It also correctly adjusts the buffer pointer in sync_single() to handle the case that the given dma_addr is not aligned on a slab boundary.

2007-07-20[SPARC64]: fix section mismatch warning in mdesc.cSam Ravnborg
Fix following warning: WARNING: vmlinux.o(.text+0x35264): Section mismatch: reference to .init.text:__alloc_bootmem (between 'mdesc_bootmem_alloc' and 'mdesc_bootmem_free') Rename mdesc_mem_ops to *_ops so modpost ignores __init references and declare mdesc_bootmem_alloc __init since it is only used during __init context.
