Revision dfea91d5a7c795fd6f4e1a97489a98e4e767463e authored by Suresh Siddha on 18 January 2010, 20:10:48 UTC, committed by Linus Torvalds on 18 January 2010, 22:15:27 UTC
Chris McDermott from IBM confirmed that hurricane chipset in IBM summit platforms doesn't support logical flat mode. Irrespective of the other things like apic_id's, total number of logical cpu's, Linux kernel should default to physical mode for this system. The 32-bit kernel does so using the OEM checks for the IBM summit platform. Add a similar OEM platform check for the 64bit kernel too. Otherwise the linux kernel boot can hang on this platform under certain bios/platform settings.
