target/arm/translate-a64: Don't underdecode SIMD ld/st single
In the AdvSIMD load/store single structure encodings, the
non-post-indexed case should have zeroes in [20:16] (which is the
Rm field for the post-indexed case). Bit 31 must also be zero
(a check we got right in ldst_multiple but not here). Correctly
UNDEF these unallocated encodings.

target/arm/translate-a64: Don't underdecode SIMD ld/st multiple
In the AdvSIMD load/store multiple structures encodings,
the non-post-indexed case should have zeroes in [20:16]
(which is the Rm field for the post-indexed case).
Correctly UNDEF the currently unallocated encodings which
have non-zeroes in those bits.

target/arm/translate-a64: Don't underdecode PRFM
The PRFM prefetch insn in the load/store with imm9 encodings
requires idx field 0b00; we were underdecoding this by
only checking !is_unpriv (which is equivalent to idx != 2).
Correctly UNDEF the unallocated encodings where idx == 0b01
and 0b11 as well as 0b10.

target/arm/translate-a64: Don't underdecode system instructions
The "system instructions" and "system register move" subcategories
of "branches, exception generating and system instructions" for A64
only apply if bits [23:22] are zero; other values are currently
unallocated. Correctly UNDEF these unallocated encodings.

target/m68k: Fix LGPL information in the file headers
It's either "GNU *Library* General Public License version 2" or
"GNU Lesser General Public License version *2.1*", but there was
no "version 2.0" of the "Lesser" license. So assume that version
2.1 is meant here.
Also some files mention the GPL instead of the LGPL after declaring
that the files are licensed under the LGPL, so change these spots to
use LGPL, too.

Don't talk about the LGPL if the file is licensed under the GPL
Some files claim that the code is licensed under the GPL, but then
suddenly suggest that the user should have a look at the LGPL.
That's of course non-sense, replace it with the correct GPL wording
instead.

i386: Enable NPT and NRIPSAVE for AMD CPUs
Modern AMD CPUs support NPT and NRIPSAVE features and KVM exposes these
when present. NRIPSAVE apeared somewhere in Opteron_G3 lifetime (e.g.
QuadCore AMD Opteron 2378 has is but QuadCore AMD Opteron HE 2344 doesn't),
NPT was introduced a bit earlier.

Add the FEAT_SVM leaf to Opteron_G4/G5 and EPYC/EPYC-IBPB cpu models.

qom/cpu: Add cluster_index to CPUState
For TCG we want to distinguish which cluster a CPU is in, and
we need to do it quickly. Cache the cluster index in the CPUState
struct, by having the cluster object set cpu->cluster_index for
each CPU child when it is realized.

This means that board/SoC code must add all CPUs to the cluster
before realizing the cluster object. Regrettably QOM provides no
way to prevent adding children to a realized object and no way for
the parent to be notified when a new child is added to it, so
we don't have any way to enforce/assert this constraint; all
we can do is document it in a comment. We can at least put in a
check that the cluster contains at least one CPU, which should
catch the typical cases of "realized cluster too early" or
"forgot to parent the CPUs into it".

The restriction on how many clusters can exist in the system
is imposed by TCG code which will be added in a subsequent commit,
but the check to enforce it in cluster.c fits better in this one.

target/arm: Don't clear supported PMU events when initializing PMCEID1
A bug was introduced during a respin of:

commit 57a4a11b2b281bb548b419ca81bfafb214e4c77a
target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0

This patch introduced two calls to get_pmceid() during CPU
initialization - one each for PMCEID0 and PMCEID1. In addition to
building the register values, get_pmceid() clears an internal array
mapping event numbers to their implementations (supported_event_map)
before rebuilding it. This is an optimization since much of the logic is
shared. However, since it was called twice, the contents of
supported_event_map reflect only the events in PMCEID1 (the second call
to get_pmceid()).

Fix this bug by moving the initialization of PMCEID0 and PMCEID1 back
into a single function call, and name it more appropriately since it is
doing more than simply generating the contents of the PMCEID[01]
registers.

exec.c: Use correct attrs in cpu_memory_rw_debug()
In the softmmu version of cpu_memory_rw_debug(), we ask the
CPU for the attributes to use for the virtual memory access,
and we correctly use those to identify the address space
index. However, we were not passing them in to the
address_space_write_rom() and address_space_rw() functions.

The effect of this was that a memory access from the gdbstub
to a device which had behaviour that was sensitive to the
memory attributes (such as some ARMv8M NVIC registers) was
incorrectly always performed as if non-secure, rather than
using the right security state for the CPU's current state.

target/mips: Correct the second argument type of cpu_supports_isa()
"insn_flags" bitfield was expanded from 32-bit to 64-bit in commit
f9c9cd63e3. However, this was not reflected on the second argument
of the function cpu_supports_isa(). By chance, this did not create
some wrong behavior, since the left-most halves of all instances of
the second argument are currently all zeros. However, this is still
a bug waiting to happen. Correct this by changing the type of the
second argument to be always 64-bit.
