0c8465440d hmp: obsolete "info ioapic"
Let's start to use "info pic" just like other platforms.  For now we
keep the command for a while so that old users can know what is the new
command to use.

9f75079498 sev/i386: add sev_get_capabilities()
The function can be used to get the current SEV capabilities.
The capabilities include platform diffie-hellman key (pdh) and certificate
chain. The key can be provided to the external entities which wants to
establish a trusted channel between SEV firmware and guest owner.

d8575c6c02 sev/i386: add command to initialize the memory encryption context
When memory encryption is enabled, KVM_SEV_INIT command is used to
initialize the platform. The command loads the SEV related persistent
data from non-volatile storage and initializes the platform context.
This command should be first issued before invoking any other guest
commands provided by the SEV firmware.

452fcdbc49 Include qapi/qmp/qdict.h exactly where needed
This cleanup makes the number of objects depending on qapi/qmp/qdict.h
drop from 4550 (out of 4743) to 368 in my "build everything" tree.
For qapi/qmp/qobject.h, the number drops from 4552 to 390.

While there, separate #include from file comment with a blank line.

854e67fea6 monitor: Fix crashes when using HMP commands without CPU
When running certain HMP commands ("info registers", "info cpustats",
"info tlb", "nmi", "memsave" or dumping virtual memory) with the "none"
machine, QEMU crashes with a segmentation fault. This happens because the
"none" machine does not have any CPUs by default, but these HMP commands
did not check for a valid CPU pointer yet. Add such checks now, so we get
an error message about the missing CPU instead.

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.

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.
