* Revert "MIPS: Allow ASID size to be determined at boot time."David Daney2013-05-16
| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit d532f3d26716a39dfd4b88d687bd344fbe77e390. The original commit has several problems: 1) Doesn't work with 64-bit kernels. 2) Calls TLBMISS_HANDLER_SETUP() before the code is generated. 3) Calls TLBMISS_HANDLER_SETUP() twice in per_cpu_trap_init() when only one call is needed. [ralf@linux-mips.org: Also revert the bits of the ASID patch which were hidden in the KVM merge.] Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Cc: "Steven J.

* MIPS: Allow ASID size to be determined at boot time.Steven J. Hill2013-05-08
| | | | | | | | | | | | | | | Original patch by Ralf Baechle and removed by Harold Koerfgen with commit f67e4ffc79905482c3b9b8c8dd65197bac7eb508. This allows for more generic kernels since the size of the ASID and corresponding masks can be determined at run-time. This patch is also required for the new Aptiv cores and has been tested on Malta and Malta Aptiv platforms.

* MIPS: Add CONFIG_CPU_R5500 for NEC VR5500 series processorsShinya Kuribayashi2008-10-27
| | | | | | | | | | | | We already have sufficient infrastructure to support VR5500 and VR5500A series processors. Here's a Makefile support to make it selectable by ports, and enable it for NEC EMMA2RH Markeins board. This patch also fixes a confused target help, and adds 1Gb PageMask bits supported by VR5500 and its variants.
