The function get_fd extract context from the received MAD message and
uses it as a key to fetch the destination fd from the mapping table.
A context can be dgid in case of CM request message or comm_id in case
of CM SIDR response message.

When MAD message with a smaller size as expected for the message type
received we are hitting out-of-bounds where we are looking for the
context out of message boundaries.

Fix it by validating the message size.

This patch fixes two issues in the hppa/parisc emulation:

1. The CPU HPA was wrong in the sense that we had negative module
offsets in the firmware-internal module table (which we ignored up to
now). Get it correct by changing the CPU HPA to 0xfffb0000 which is
greater than the DINO_HPA of 0xfff80000.
This change requires the seabios-firmware update.

2. Sven noticed that the FPU register cr10 is only able to reference up
to 8 FPUs, so let's reduce the maximum amount of SMP CPUs too.

Within a delay slot, we were squishing both DISAS_IAQ_N_STALE and
DISAS_IAQ_N_STALE_EXIT to DISAS_IAQ_N_UPDATED.  This lost the

never being delivered.

Some generic arch timer registers are Config-RW in the EL0,
which means the EL0 exception level can have write permission
if it is appropriately configured.

When VM access registers, QEMU firstly checks whether they have RW
permission, then check whether it is appropriately configured.
If they are defined to read only in EL0, even though they have been
appropriately configured, they still do not have write permission.
So need to add the write permission according to ARMV8 spec when
define it.

target/riscv: Convert to decodetree

Bastian: this patchset converts the RISC-V decoder to decodetree in four major steps:

1) Convert 32-bit instructions to decodetree [Patch 1-15]:
    Many of the gen_* functions are called by the decode functions for 16-bit
    and 32-bit functions. If we move translation code from the gen_*
    functions to the generated trans_* functions of decode-tree, we get a lot of
    duplication. Therefore, we mostly generate calls to the old gen_* function
    which are properly replaced after step 2).

    Each of the trans_ functions are grouped into files corresponding to their
    ISA extension, e.g. addi which is in RV32I is translated in the file
    'trans_rvi.inc.c'.

2) Convert 16-bit instructions to decodetree [Patch 16-18]:
    All 16 bit instructions have a direct mapping to a 32 bit instruction. Thus,
    we convert the arguments in the 16 bit trans_ function to the arguments of
    the corresponding 32 bit instruction and call the 32 bit trans_ function.

3) Remove old manual decoding in gen_* function [Patch 19-29]:
    this move all manual translation code into the trans_* instructions of
    decode tree, such that we can remove the old decode_* functions.

Palmer: This, with some additional cleanup patches, passed Alistar's
testing on rv32 and rv64 as well as my testing on rv64, so I think it's
good to go.  I've run my standard test against this exact tag.

I still don't have a Mac to try this on, sorry!
