> 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. > > Signed-off-by: Khalid Aziz <khalid.a...@oracle.com> Applied. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
