MFC r274337,r274673,274681,r275515:
ZFS large block support. The default recordsize remains at 128KB.
A new tunable/sysctl variable, vfs.zfs.max_recordsize is added to allow adjusting the permitted maximum record size, or zfs_max_recordsize, with a default of 1MB. ZFS will not allow setting recordsize greater than zfs_max_recordsize as a safety belt, because larger recordsize means greater read and write latency and more memory usage.
Please note that booting from datasets that have recordsize greater than 128KB is not supported (but it's Okay to enable the feature on the pool).
Limited safety belt is provided for mounted root filesystem but use caution when using a larger value.

MFV r245512:
* Illumos zfs issue #3035 [1] LZ4 compression support in ZFS.
LZ4 is a new high-speed BSD-licensed compression algorithm created by Yann Collet that delivers very high compression and decompression performance compared to lzjb (>50% faster on compression, >80% faster on decompression and around 3x faster on compression of incompressible data), while giving better compression ratio [1].
This version of LZ4 corresponds to upstream's [2] revision 85.
Please note that for obvious reasons this is not backward read compatible. This means once a pool have LZ4 compressed data, these data can no longer be read by older ZFS implementations.
Local changes:
- On-stack hash table disabled and using kernel slab allocator instead, at this time. This requires larger kernel thread stack for zio workers. This may change in the future should we adjusted the zio workers' thread stack size. - likely and unlikely will be undefined if they are already defined, this is required for i386 XEN build. - Removed De Bruijn sequence based __builtin_ctz family of builtins in favor of the latter. Both GCC and clang supports these builtins. - Changed the way the LZ4 code detects endianness. - Manual pages modifications to mention the feature based on Illumos counterpart. - Boot loader changes to make it support LZ4 decompression.
