Encapsulate the buddy allocator used for MTT segments. This cleans up the code and also gets us ready to add FMR support. Signed-off-by:

Fix bug in MTT allocation in mem-free mode. I misunderstood the MTT size value returned by the firmware -- it is really the size of a single MTT entry, since mem-free mode does not segment the MTT as the original firmware did. This meant that our MTT addresses ended up being off by a factor of 8. This meant that our MTT allocations might overlap, and so we could overwrite and corrupt earlier memory regions when writing new MTT entries. We fix this by always using our 64-byte MTT segment size. This allows some simplification of the code as well, since there's no reason to put the MTT segment size in a variable -- we can always use our enum value directly. Signed-off-by:

Doorbell record pages are allocated in HCA page size chunks (always 4096 bytes), so we need to divide by 4096 and not PAGE_SIZE when figuring out how many pages we'll need space for. Signed-off-by:

Correct and simplify calculation of static rate. We need to round up the quotient of (local_rate - path_rate) / path_rate. To round up we add (path_rate - 1) to the numerator, so the quotient simplifies to (local_rate - 1) / path_rate. No idea how I came up with the old formula. Signed-off-by:

gcc-4 warns with include/linux/cpuset.h:21: warning: type qualifiers ignored on function return type cpuset_cpus_allowed is declared with const extern const cpumask_t cpuset_cpus_allowed(const struct task_struct *p); First const should be __attribute__((const)), but the gcc manual explains that: "Note that a function that has pointer arguments and examines the data pointed to must not be declared const. Likewise, a function that calls a non-const function usually must not be const. It does not make sense for a const function to return void." The following patch remove const from the function declaration. Signed-off-by:

IXP2000 (ARM-based) platforms use a separate 'struct resource' for PCI MEM space. Resource allocation for PCI BARs always fails because the 'root' resource (the IXP2000 PCI MEM resource) always has the entire address space (00000000-ffffffff) free, and find_resource() calculates the size of that range as ffffffff-00000000+1=0, so all allocations fail because it thinks there is no space.

In the new io infrastructure, all of our operators are expecting the underlying device to be little endian (because the PCI bus, their main consumer, is LE). However, there are a fair few devices and busses in the world that are actually Big Endian. There's even evidence that some of these BE bus and chip types are attached to LE systems. Thus, there's a need for a BE equivalent of our io{read,write}{16,32} operations. The attached patch adds this as io{read,write}{16,32}be. When it's in, I'll add the first consume (the 53c700 SCSI chip driver). Signed-off-by:James Bottomley <James.Bottomley@SteelEye.com> Signed-off-by:
