We tagged this one with LP: #1804481 in disco because it was part of a series that enabled signing. But, in bionic the actual arm64 *signing* bits already landed. Since I submitted this, the regression *this* patch fixes was reported as LP: #1828553. So, it may make sense to just consider LP: #1804481 closed and reference LP: #1828553 in the commit. -dann > Our arm64 generic kernels are compressed, but they must be > decompressed for signing.
