From 0bf757c73d6612d3d279de3f61b35062aa9c8b1d Mon Sep 17 00:00:00 2001 From: Mark Salter Date: Mon, 7 Apr 2014 15:39:51 -0700 Subject: arm64: initialize pgprot info earlier in boot Presently, paging_init() calls init_mem_pgprot() to initialize pgprot values used by macros such as PAGE_KERNEL, PAGE_KERNEL_EXEC, etc. The new fixmap and early_ioremap support also needs to use these macros before paging_init() is called. This patch moves the init_mem_pgprot() call out of paging_init() and into setup_arch() so that pgprot_default gets initialized in time for fixmap and early_ioremap.
