1008 6731 d 11 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 6732 d 4 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.

980 6732 d 9 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.

977 6732 d 10 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6732 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6732 d 13 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6732 d 13 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
962 6733 d 2 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.

Widened syscall to support up to 5 parameters.		  
958 6733 d 4 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.

mips32 requires some attention.		  
935 6734 d 6 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
934 6734 d 6 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code

921 6737 d 6 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6737 d 11 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.		  
916 6739 d 13 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.

915 6739 d 14 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- 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.
