Khalid Aziz	494e5b6fae	sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE ... sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE Bit 9 of TTE is CV (Cacheable in V-cache) on sparc v9 processor while the same bit 9 is MCDE (Memory Corruption Detection Enable) on M7 processor. This creates a conflicting usage of the same bit. Kernel sets TTE.cv bit on all pages for sun4v architecture which works well for sparc v9 but enables memory corruption detection on M7 processor which is not the intent. This patch adds code to determine if kernel is running on M7 processor and takes steps to not enable memory corruption detection in TTE erroneously.

Sam Ravnborg	f05a68653e	sparc: drop use of extern for prototypes in arch/sparc/include/asm ... Drop extern for all prototypes and adjust alignment of parameters as required after the removal. In a few rare cases adjust linelength to conform to maximum 80 chars, and likewise in a few rare cases adjust alignment of parameters to static functions.

David S. Miller	5a5488d3bb	sparc64: Store per-cpu offset in trap_block[] ... Surprisingly this actually makes LOAD_PER_CPU_BASE() a little more efficient. Signed-off-by: David S. Miller <davem@davemloft.net>	2009-06-16 04:56:11 -07:00
David S. Miller	19f0fa3fb3	sparc64: Move trap_block[] definitions into a new header file. ... Later we're going to want to get at these definitions from asm/percpu.h and that's not possible via cpudata.h because of the set of dependencies the non-trap_block[] stuff has.
