Description Jan Friesse 2011-05-26 04:08:22 EDT

Created attachment 501008 [details]
Align IPC to 8-bit

Description of problem:
Align ipc on 8 byte boundaries

Align all ipc messages on 8 byte boundaries.  This alignment will remove bus
errors on systems that can't access non-byte aligned data and should improve
performance.

Fix problem where unaligned totemip address access would result in bus error on non-unaligned-safe architectures

  
Actual results:
Crash on non x86 (Sparc, PPC, ...)

Expected results:
No crash on non x86
