David Hildenbrand 7f579e272f exec,dump,i386,ppc,s390x: don't include exec/cpu-all.h explicitly
All but a handful of files include exec/cpu-all.h via cpu.h only.
As these files already include cpu.h, let's just drop the additional
include.

Kirill A. Shutemov 6c7c3c21f9 x86: implement la57 paging mode
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.

Thomas Huth fcf5ef2ab5 Move target-* CPU file into a target/ folder
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.
