This series implements
- detection of installed physical memory
- setup of the physical allocator
- setup of the MMU / page tables / DAT
- setup of the virtual allocator
The CPU now runs with DAT enabled. I added a small test to make sure
malloc() indeed works and uses virtual adresses. Also, the sieve test
is added.
While at it, fix the TEST BLOCK test on newer compilers.
Tested with upsteam QEMU TCG and KVM. However, to pass under TCG a
fix is necessary ("[PATCH v1] s390x/tcg: fix disabling/enabling DAT").
v2 -> v3:
- split up configure_dat() to make use of two functions extract_psw_mask()
and load_psw_mask(), it is now much cleaner and we might need these
functions in the future.
- Minor cleanups / comment fixes
