[PATCH] powerpc: Name xpn x fields in HW pte format

2009-08-24 Thread Becky Bruce
Previously, the 36-bit code was using these bits, but they had never been named in the pte format definition. This patch just gives those fields their proper names and adds a comment that they are only present on some processors. There is no functional code change. Signed-off-by: Becky Bruce

Previously, this was specified as a void *, but that's not large enough on 32-bit systems with 36-bit physical addressing support. Change the type to dma_addr_t so it will scale based on the size of a dma address. Signed-off-by: Becky Bruce bec...@kernel.crashing.org ---

Hello everyone, I have the Freescale's MPC8313erdb eval board and run the latest stable linux kernel version (linux-2.6.30.5). After creating a VLAN device (e.g. eth0.2) a VLAN tag is also inserted into frames that don't relate to a VLAN device. This is the case for frames that are directly

Support for TLB reservation (or TLB Write Conditional) and Paired MAS registers are optional for a processor implementation so we handle them via MMU feature sections. We currently only used paired MAS registers to access the full RPN + perm bits that are kept in MAS7||MAS3. We assume that if an
