David Sterba ccaa66c8dd Revert "btrfs: compression: drop kmap/kunmap from lzo" ... This reverts commit 8c945d32e6. The kmaps in compression code are still needed and cause crashes on 32bit machines (ARM, x86). Reproducible eg. by running fstest btrfs/004 with enabled LZO or ZSTD compression. The revert does not apply cleanly due to changes in a6e66e6f8c ("btrfs: rework lzo_decompress_bio() to make it subpage compatible") that reworked the page iteration so the revert is done to be equivalent to the original code.
