Stefan Lankes	a2b36849d9	create for each task an interrupt stack table (IST1) ... Currently, "user-level" code has to deactivate the red zone support. To avoid this, we create an interrupt stack table (IST1), which is the default stack for all interrupts. Consequently, the common stack isn't touch by handling any interrupt and the red-zone could be used for compiler optimizations. By using IST1, nested interrupts (beside NMI) arn't longer supported. But HermitCores doesn't rely on this support.	2016-06-03 06:24:46 +02:00
Stefan Lankes	82d5ec690e	add function for the stack creation, protect stack by the NX flags	2016-05-26 10:04:45 +02:00
Stefan Lankes	12553532db	page mapping set the no execustion flag to protect the data	2016-05-22 07:24:56 +02:00
Stefan Lankes	545073235a	simplify memory management ... HermitCore is a single-address space operating system => only one global lock is required to protect the page tables and the VMA structure. Furthermore, obsolete code to duplicate tasks is removed.	2016-03-21 00:18:45 +01:00
