Subject: [PATCH v2 07/37] powerpc: Untangle fixmap.h and pgtable.h and mmu.h
Date: Mon, 25 Sep 2023 20:31:21 +0200 [thread overview]
Message-ID: <5eba12392a018be28ad0a02ed844767b132589e7.1695659959.git.christophe.leroy@csgroup.eu> (raw)
In-Reply-To: <cover.1695659959.git.christophe.leroy@csgroup.eu>
fixmap.h need pgtable.h for [un]map_kernel_page()
pgtable.h need fixmap.h for FIXADDR_TOP.
Untangle the two files by moving FIXADDR_TOP into pgtable.h
Also move VIRT_IMMR_BASE to fixmap.h to avoid fixmap.h in mmu.h
