* [PATCH] Rewritten backlight infrastructure for portable Apple computersMichael Hanselmann2006-06-25
| | | | | | | | | | | | | | | | This patch contains a total rewrite of the backlight infrastructure for portable Apple computers. Backward compatibility is retained. A sysfs interface allows userland to control the brightness with more steps than before. Userland is allowed to upload a brightness curve for different monitors, similar to Mac OS X.

* [PATCH] Clean up and refactor i386 sub-architecture setupJeremy Fitzhardinge2006-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Clean up and refactor i386 sub-architecture setup. This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.

* [PATCH] mm: remove VM_LOCKED before remap_pfn_range and drop VM_SHMChristoph Lameter2006-06-25
| | | | | | | | | | | | | | | | | Remove VM_LOCKED before remap_pfn range from device drivers and get rid of VM_SHM. remap_pfn_range() already sets VM_IO. There is no need to set VM_SHM since it does nothing. VM_LOCKED is of no use since the remap_pfn_range does not place pages on the LRU. The pages are therefore never subject to swap anyways. Remove all the vm_flags settings before calling remap_pfn_range. After removing all the vm_flag settings no use of VM_SHM is left. Drop it.

| | * [ARM] 3648/1: Update struct ucontext layout for coprocessor registersDaniel Jacobowitz2006-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Daniel Jacobowitz In order for userspace to find saved coprocessor registers, move them from struct rt_sigframe into struct ucontext. Also allow space for glibc's sigset_t, so that userspace and kernelspace can use the same ucontext layout. Define the magic numbers for iWMMXt in the header file for easier reference. Include the size of the coprocessor data in the magic numbers. Also define magic numbers and layout for VFP, not yet saved.

Discussing this issue with glibc folk: | > Additionally, do you see any need for these weird "puc" and "pinfo" | > pointers in the kernels rt_sigframe structure? Can we kill them? | | We can kill them. I checked with Phil B. about them last week, and he | didn't remember any reason they still needed to be there. And nothing | should know where they are on the stack. Unfortunately, doing this | will upset GDB, which knows that the saved registers are 0x88 bytes | above the stack pointer on entrance to an rt signal trampoline; but, | since puc and pinfo are quite recognizable, I can adapt GDB to support | the new layout if you want to remove them. So remove them. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
