To: Cciss-discuss; +Cc: linux-kernel, trivial
The patch below postfixes a constant in cciss.h with ULL, on 32 bit
archs this constant is too big for an int.
The cast doesn't do the right thing, 0xffffffffffffffff is in C an int
and the cast casts 0xffffffffffffffff interpreted as an int to an u64.
Please apply
Adrian
