spapr_vscsi: Fix REPORT_LUNS handling
Intercept REPORT_LUNS commands addressed either to SRP LUN 0 or the well-known
LUN for REPORT_LUNS commands. This is required to implement the SAM and SPC
specifications.
Since SRP implements only a single SCSI target port per connection, the SRP
target is required to report all available LUNs in response to a REPORT_LUNS
command addressed either to LUN 0 or the well-known LUN. Instead, QEMU was
forwarding such requests to the first QEMU SCSI target, with the result that
initiators that relied on this feature would only see LUNs on the first QEMU
SCSI target.
Behavior for REPORT_LUNS commands addressed to any other LUN is not specified
by the standard and so is left unchanged. This preserves behavior under Linux

mmu-hash64: fix Virtual Page Class Key Protection
commit
f80872e21c07edd06eb343eeeefc8af404b518a6 (mmu-hash64: Implement
Virtual Page Class Key Protection) added a new page protection
mechanism based on page keys and the AMR register to control access.
The AMR register allows or prohibits reads and/or writes on a page
depending on the control bits associated to the key. A store or a load
is only permitted if the associate bit is 0 (Power ISA), and not 1 as
the code is currently doing. This patch modifies ppc_hash64_amr_prot()
to correct the protection check.
This issue was unvailed by commit
ccfb53ed6360cac0d5f6f7915ca9ae7eed866412

The existing default value (-1) of the AMR register forbids data access
to all 32 classes. Since the guest linux does not change this register,
we end up with the guest hanging right after switching from the real to
protected mode.
This sets the default AMR value to zero what enables data access for all
classes.
The only reason for not hitting this bug before is that
kvm_arch_put_registers() did not put any SPR to KVM due to missing
assignment of @one_reg_id in _spr_register() (which is going to be fixed

Visitors get passed a pointer to the visited object. The generated
visitors try to cope with this pointer being null in some places, for
instance like this:
visit_start_optional(m, obj ? &(*obj)->has_name : NULL, "name", &err);
visit_start_optional() passes its second argument to Visitor method
start_optional. Three out of three methods dereference it
unconditionally.
I fail to see how this pointer could legitimately be null.

qjson.h: Remove spurious GCC_FMT_ATTR markup from qobject_from_json() declaration
The function qobject_from_json() doesn't actually allow its
argument to be a format string -- it passes a NULL va_list*
to qobject_from_jsonv(), and the parser code will then never
actually interpret %-escape sequences (it tests whether the
va_list pointer is NULL and will stop with a parse error).
The spurious attribute markup causes clang warnings in some
of the test cases where we programmatically construct JSON
to feed to qobject_from_json():

dump: make kdump-compressed format available for 'dump-guest-memory'
Make monitor command 'dump-guest-memory' be able to dump in kdump-compressed
format. The command's usage:
dump [-p] protocol [begin] [length] [format]
'format' is used to specified the format of vmcore and can be:
1. 'elf': ELF format, without compression
2. 'kdump-zlib': kdump-compressed format, with zlib-compressed
3. 'kdump-lzo': kdump-compressed format, with lzo-compressed
4. 'kdump-snappy': kdump-compressed format, with snappy-compressed
Without 'format' being set, it is same as 'elf'. And if non-elf format is
specified, paging and filter is not allowed.
Note:
1. The kdump-compressed format is readable only with the crash utility and
makedumpfile, and it can be smaller than the ELF format because of the
compression support.
2. The kdump-compressed format is the 6th edition.
