| * | arm64: use correct register width when retrieving ASID | Matthew Leach | 2013-09-25 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | The ASID is represented as an unsigned int in mm_context_t and we currently use the mmid assembler macro to access this element of the struct. This should be accessed with a register of 32-bit width. If the incorrect register width is used the ASID will be returned in bits[32:63] of the register when running under big-endian. Fix a use of the mmid macro in tlb.S to use a 32-bit access.

| * | arm64: TLB maintenance functionality | Catalin Marinas | 2012-09-17 | 1 | -0/+71 |
| This patch adds the TLB maintenance functions. There is no distinction made between the I and D TLBs. TLB maintenance operations are automatically broadcast between CPUs in hardware. The inner-shareable operations are always present, even on UP systems. NOTE: Large part of this patch to be dropped once Peter Z's generic mmu_gather patches are merged.
