commit a0c3cd03ce76313a7c461ecb3e70b513a15453f7 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> AuthorDate: Mon Dec 6 13:07:08 2021 +0000 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Thu Dec 9 16:26:29 2021 +0000 x86/build: Move exception tables into __ro_after_init Since c/s 79713ed0a94c ("x86: move both exception tables into .rodata") in 2016, we've been (ab)using the fact that .rodata is read/write during early boot, so we can sort the two tables. Now that we have a real __ro_after_init concept, reposition them to better match reality.
