2011-05-19m68k: Merge mmu and non-mmu versions of sys_call_tableGeert Uytterhoeven
Impact for nommu: - Store table in .rodata instead of .text, - Let kernel/sys_ni.c handle the stubbing of MMU-only syscalls, - Implement sys_mremap and sys_nfsservct, - Remove unused padding at the end of the table. Impact for mmu: - Store table in .rodata instead of .data. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Greg Ungerer <gerg@uclinux.org>

2011-05-19m68k: bitops - Never step beyond the end of the bitmapGeert Uytterhoeven
find_next bitops on m68k (find_next_zero_bit, find_next_bit, and find_next_bit_le) may cause out of bounds memory access when the bitmap size in bits % 32 != 0 and offset (the bitnumber to start searching at) is very close to the bitmap size. For example, unsigned long bitmap[2] = { 0, 0 }; find_next_bit(bitmap, 63, 62); 1. find_next_bit() tries to find any set bits in bitmap[1], but no bits set. 2. Then find_first_bit(bimap + 2, -1) 3. Unfortunately find_first_bit() takes unsigned int as the size argument. 4. find_first_bit will access bitmap[2~] until it find any set bits. Add missing tests for stepping beyond the end of the bitmap to all find_{first,next}_*() functions, and make sure they never return a value larger than the bitmap size.

2011-05-19x86: Don't unmask disabled irqs when migrating themTian, Kevin
It doesn't make sense to unconditionally unmask a disabled irq when migrating it from offlined cpu to another. If the irq triggers then it will be disabled in the interrupt handler anyway. So we can just avoid unmasking it.

Some embedded devices like the Netgear WNDR3300 have two SSB based cards without an own sprom on the pci bus. We have to provide two different fallback sproms for these and this was not possible with the old solution. In the bcm47xx architecture the sprom data is stored in the nvram in the main flash storage. The architecture code will be able to fill the sprom with the stored data based on the bus where the device was found. The bcm63xx code should do the same thing as before, just using the new API.
