From 9eb8f6743b076b67f00776cda4330c802e157b41 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Thu, 28 Apr 2011 14:27:20 -0600 Subject: arm/dt: Allow CONFIG_OF on ARM Add some basic empty infrastructure for DT support on ARM. v5: - Fix off-by-one error in size calculation of initrd - Stop mucking with cmd_line, and load command line from dt into boot_command_line instead which matches the behaviour of ATAGS booting v3: - moved cmd_line export and initrd setup to this patch to make the series bisectable. - switched to alloc_bootmem_align() for allocation when unflattening the device tree. memblock_alloc() was not the right interface.

The fix to this problem checks that the pfn <-> page linkages are correct by calculating the page for the pfn and then checking that page_to_pfn on that page returns the original pfn. Unfortunately, in SPARSEMEM configurations, this results in reading from the page flags to determine the correct section. Since the memmap here has been freed, junk is read from memory and the check is no longer robust. In the best case, reading from /proc/pagetypeinfo will give you the wrong answer. In the worst case, you get SEGVs, Kernel OOPses and hung CPUs. Furthermore, ioremap implementations that use pfn_valid to disallow the remapping of normal memory will break. This patch allows architectures to provide their own pfn_valid function instead of using the default implementation used by sparsemem. The architecture-specific version is aware of the memmap state and will return false when passed a pfn for a freed page within a valid section.
