Revision 966a0acce2fca776391823381dba95c40e03c339 authored by Sami Tolvanen on 30 July 2020, 15:37:01 UTC, committed by Will Deacon on 30 July 2020, 15:50:14 UTC
Commit f7b93d42945c ("arm64/alternatives: use subsections for replacement sequences") breaks LLVM's integrated assembler, because due to its one-pass design, it cannot compute instruction sequence lengths before the layout for the subsection has been finalized. This change fixes the build by moving the .org directives inside the subsection, so they are processed after the subsection layout is known.
