[PATCH v2 2/9] arm64: mm: free __init memory via the linear mapping
From: Ard Biesheuvel <hidden>

Subsystem:
arm64 port (aarch64 architecture), the rest · Maintainers:
Catalin Marinas, Will Deacon, Linus Torvalds
The implementation of free_initmem_default() expects __init_begin and __init_end to be covered by the linear mapping, which is no longer the case. So open code it instead, using addresses that are explicitly translated from kernel virtual to linear virtual.
