linux-toradex.git/arch/arm/mm/idmap.c, branch v3.2.64 Linux kernel for Apalis and Colibri modules ARM: pgtable: add pud-level code 2011-02-21T19:24:14+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-21T16:27:49+00:00 516295e5ab4bf986865cfff856d484ec678e3b0b Add pud_offset() et.al. between the pgd and pmd code in preparation of using pgtable-nopud.h rather than 4level-fixup.h. This incorporates a fix from Jamie Iles <jamie@jamieiles.com> for uaccess_with_memcpy.c. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

ARM: pgtable: use conventional page table code for identity mappings 2010-12-22T11:05:34+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-21T11:48:16+00:00 af3813d6a5bf8d0f71b23d3ce458fa5f9916c6b7 Remove some knowledge of our 2-level page table layout from the identity mapping code - we assume that a step size of PGDIR_SIZE will allow us to step over all entries. While this is true today, it won't be true in the near future. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

ARM: pgtable: collect up identity mapping functions 2010-12-22T11:05:33+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-11-21T11:41:57+00:00 614dd0585f376a25c638abbed9c5fbd21d7baece We have two places where we create identity mappings - one when we bring secondary CPUs online, and one where we setup some mappings for soft- reboot. Combine these two into a single implementation. Also collect the identity mapping deletion function. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
