1008 6650 d 23 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.

993 6651 d 15 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.

frame zones initialization		  
970 6652 d 0 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6652 d 1 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.

There is an unrelated show stopper, however.		  
919 6656 d 23 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.

- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.
