2016-12-22x86: implement la57 paging modeKirill A. Shutemov
The new paging more is extension of IA32e mode with more additional page table level. It brings support of 57-bit vitrual address space (128PB) and 52-bit physical address space (4PB). The structure of new page table level is identical to pml4. The feature is enumerated with CPUID.(EAX=07H, ECX=0):ECX[bit 16]. CR4.LA57[bit 12] need to be set when pageing enables to activate 5-level paging mode. Signed-off-by: Kirill A.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
