Double large kmalloc warning size to 4 pages. It was 2 pages, and ideally it should be dropped to one page but in the short term we should be able to easily live with 4 page allocations. Fix the nvlist bug, it turns out the user space side of things were packing the nvlists correctly as little endian, and the kernel space side of things due to a missing #define were unpacking them as big endian. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@62 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c

Powerpc Fixes (part 1): - Enable builds for powerpc ISA type. - Add DIV_ROUND_UP and roundup macros if unavailable. - Cast 64-bit values for %lld format string to (long long) to quiet compile warning.

Either _ILP32 or _LP64 must be defined For some arm, powerpc, and sparc platforms it was possible that neither _ILP32 of _LP64 would be defined. Update the isa_defs.h header to explicitly set these macros and generate a compile error in the case neither are defined.

/* arm arch specific defines */
Add support for aarch64 (ARMv8) Using the ARM reference simulation (fast model foundation v8) I cross compiled spl and zfs, to confirm it works on ARMv8 (64 bit arm architecture, called aarch64 in Linux). As it is based on previous ARM porting, the resulting patch is disappointingly small, there was very little to do. The code fixes the compile issues and has light testing done.
