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>

2006-06-22[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.

2006-06-19[MIPS] Cleanup memory managment initialization.Ralf Baechle
Historically plat_mem_setup did the entire platform initialization. This was rather impractical because it meant plat_mem_setup had to get away without any kind of memory allocator. To keep old code from breaking plat_setup was just renamed to plat_setup and a second platform initialization hook for anything else was introduced. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2006-06-19[MIPS] Drop 0 definition for kern_addr_validRalf Baechle
kern_addr_valid is currently only being used in kmem_ptr_validate which is making some vague attempt at verfying the validity of an address. Only IA-64, PARISC and x86-64 actually make some actual effort to verify the validity of the pointer. Most architecture definitions of kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM on i386 and MIPS even as 0; the 0-definition will result in kmem_ptr_validate always failing which in turn will cause d_validate to always fail. d_validate's only two users are smbfs and ncpfs, so the 0 definition ended breaking those ...

2006-06-19[MIPS] Fix futex_atomic_op_inuser.Atsushi Nemoto
I found that NPTL's pthread_cond_signal() does not work properly on kernels compiled by gcc 4.1.x. I suppose inline asm for __futex_atomic_op() was wrong. I suppose: 1. "=&r" constraint should be used for oldval. 2. Instead of "r" (uaddr), "=R" (*uaddr) for output and "R" (*uaddr) for input should be used. 3. "memory" should be added to the clobber list.

Move memory_present() in arch/mips/kernel/setup.c. When using sparsemem extreme, this function does an allocate for bootmem. This would always fail since init_bootmem hasn't been called yet.

2006-06-06[MIPS] Fix swap entry for MIPS32 36-bit physical addressSergei Shtylyov
With 64-bit physical address enabled, 'swapon' was causing kernel oops on Alchemy CPUs (MIPS32) because of the swap entry type field corrupting the _PAGE_FILE bit in 'pte_low' field. So, switch to storing the swap entry in 'pte_high' field using all its bits except _PAGE_GLOBAL and _PAGE_VALID which gives 25 bits for the swap entry offset.

2006-06-01[SPARC64]: Fix D-cache corruption in mremapDavid S. Miller
If we move a mapping from one virtual address to another, and this changes the virtual color of the mapping to those pages, we can see corrupt data due to D-cache aliasing. Check for and deal with this by overriding the move_pte() macro. Set things up so that other platforms can cleanly override the move_pte() macro too. Signed-off-by: David S.
