2006-06-25[PATCH] random: remove SA_SAMPLE_RANDOM from floppy driverMatt Mackall
The floppy driver is already calling add_disk_randomness as it should, so this was redundant. Signed-off-by: Matt Mackall <mpm@selenic.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-06-24[ARM] 3648/1: Update struct ucontext layout for coprocessor registersDaniel Jacobowitz
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.

2006-06-22[PATCH] vgacon: make VGA_MAP_MEM take size, remove extra useBjorn Helgaas
VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense to do this to vga_vram_base, because we're going to access memory between vga_vram_base and vga_vram_end. But it doesn't really make sense to map starting at vga_vram_end, because we aren't going to access memory starting there. On ia64, which always has to be different, ioremapping vga_vram_end gives you something completely incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being nonsense. As a bonus, we often know the size up front, so we can use ioremap() correctly, rather than giving it a zero size. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Cc: "Antonino A.

2006-06-22[ARM] Add thread_notify infrastructureRussell King
Some machine classes need to allow VFP support to be built into the kernel, but still allow the kernel to run even though VFP isn't present. Unfortunately, the kernel hard-codes VFP instructions into the thread switch, which prevents this being run-time selectable. Solve this by introducing a notifier which things such as VFP can hook into to be informed of events which affect the VFP subsystem (eg, creation and destruction of threads, switches between threads.)

Patch from Andrew Victor This patch adds the core Power Management support for the AT91RM9200 processor. It will support suspend-to-RAM and standby modes.
