It is chosen such that it covers the [_stext, _etext] interval of the core kernel to avoid using PLT entries unless we really have to. - Update the module PLT patch to replace the O (n^2) searches with sorting, and use a single .plt section for __init and ordinary code.

WebbSo let's get rid of our dependency on the large model for KASLR, by: - reducing the full randomization range to 4 GB, thereby ensuring that ADRP references between modules and the kernel are always in range, - reduce the spillover range to 4 GB as well, so that we fallback to a region that is still guaranteed to be in range - move the randomization …
