4666 5635 d 10 h pillai /branches/arm/kernel/arch/arm32/ Ticket #93 fix:
Exceptin handling re-written in assembly.		  
4665 5636 d 3 h pillai /branches/arm/kernel/arch/arm32/src/ Change the exception handling logic:
Exception handler switches from exception mode to kernel mode(supervisor mode) before proceeding to
the exc_dispatch() C function. This assures that exception handling is re-entrant and
kernel would not get confused with different processor modes inside the kernel.

Also fixes a kernel panic during nested interrupts.		  
4651 5643 d 4 h pillai /branches/arm/ Generic framework for arm architecture
