c09199fe73 hw/mips_cmgcr: implement RESET_BASE register in CM GCR
Implement RESET_BASE register which is local to each VP and a write to
it changes VP's reset exception base. Also, add OTHER register to
allow a software running on one VP to access other VP's local registers.

Guest can use this mechanism to specify custom address from which a VP
will start execution.

dff94251f0 hw/mips_cpc: make VP correctly start from the reset vector
When VP enters the Run state it starts execution from the reset vector.
Currently used CPU_INTERRUPT_WAKE does not do that if reset exception
base has been modified. Therefore fix that by simply resetting given VP.

Drop the usage of CPU_INTERRUPT_WAKE also in VP_STOP and instead raise
the CPU_INTERRUPT_HALT to halt a VP.

89777fd10f target-mips: add exception base to MIPS CPU
Replace hardcoded 0xbfc00000 with exception_base which is initialized with
this default address so there is no functional change here.
However, it is now exposed and consequently it will be possible to modify
it from outside of the CPU.

e8bd336dd1 hw/mips: implement Global Interrupt Controller
The Global Interrupt Controller (GIC) is responsible for mapping each
internal and external interrupt to the correct location for servicing.

The internal representation of registers is different from the specification
in order to consolidate information for each GIC Interrupt Sources and Virtual
Processors with same functionalities. For example SH_MAP00_VP00 registers are
defined like each bit represents a VP but in this implementation the equivalent
map_vp contains VP number in integer form for ease accesses. When it is being
accessed via read write functions an internal data is converted back into the
original format as the specification.

Limitations:
Level triggering only
GIC CounterHi not implemented (Countbits = 32bits)
DINT not implemented
Local WatchDog, Fast Debug Channel, Perf Counter not implemented

405140519f hw/mips: implement GIC Interval Timer
The interval timer is similar to the CP0 Count/Compare timer within
each processor. The difference is the GIC_SH_COUNTER register is global
to the system so that all processors have the same time reference.

To ease implementation, all VPs are having its own QEMU timer but sharing
global settings and registers such as GIC_SH_CONFIG.COUTNSTOP and
GIC_SH_COUNTER.

MIPS GIC Interval Timer does support upto 64 bits of Count register but
in this implementation it is limited to 32 bits only.

e5857062a6 slirp: Remove superfluous memset() calls from the TFTP code
Commit fad7fb9ccd  ("Add IPv6 support to the TFTP code")
refactored some common code for preparing the mbuf into a new
function called tftp_prep_mbuf_data(). One part of this common
code is to do a "memset(m->m_data, 0, m->m_size);" for the related
buffer first. However, at two spots, the memset() was not removed
from the calling function, so it currently done twice in these code
paths. Thus let's delete these superfluous memsets in the calling
functions now.

8e758dee66 spapr: drop reference on child object during core realization
When a core is being realized, we create a child object for each thread
of the core.

The child is first initialized with object_initialize() which sets its ref
count to 1, and then added to the core with object_property_add_child()
which bumps the ref count to 2.

When the core gets released, object_unparent() decreases the ref count to 1,
and we g_free() the object: we hence loose the reference on an unfinalized
object. This is likely to cause random crashes.

Let's drop the extra reference as soon as we don't need it, after the
thread is added to the core.

27f2458245 ppc/xics: Replace "icp" with "xics" in most places
The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains
a XICSState pointer. There *is* an ICPState structure too so this makes
the code really confusing.

This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.

a36848ff7c target-ppc: Eliminate redundant and incorrect function booke206_page_size_to_tlb
Eliminate redundant and incorrect booke206_page_size_to_tlb function
from ppce500_spin.c in preference to previously existing but newly
exported definition from e500.c

Defect analysis:

The booke206_page_size_to_tlb function in e500.c was updated in commit
2bd9543 "ppc: booke206: use MAV=2.0 TSIZE definition, fix 4G pages" to
reflect a change in the definition of MAS1_TSIZE_SHIFT from 8
(corresponding to a min TLB page size of 4kb) to a value of 7 (TLB
page size 2k).  The booke206_page_size_to_tlb() function defined in
ppce500_spin.c was never updated to reflect the change in
MAS1_TSIZE_SHIFT.

In http://lists.nongnu.org/archive/html/qemu-ppc/2016-06/msg00533.html,
Scott Wood suggested this "root cause" explanation:

SW> The patch that changed MAS1_TSIZE_SHIFT from 8 to 7 was around the
SW> same time as the patch that added this code, which is probably why
SW> adjusting it got missed.  Commit 2bd9543cd3 did update the
SW> equivalent code in ppce500_mpc8544ds.c, which now resides in
SW> hw/ppc/e500.c and has been changed to not assume a power-of-2
SW> size.  The ppce500_spin version should be eliminated.

e37dac06dc vfio/pci: Hide SR-IOV capability
The kernel currently exposes the SR-IOV capability as read-only
through vfio-pci.  This is sufficient to protect the host kernel, but
has the potential to confuse guests without further virtualization.
In particular, OVMF tries to size the VF BARs and comes up with absurd
results, ending with an assert.  There's not much point in adding
virtualization to a read-only capability, so we simply hide it for
now.  If the kernel ever enables SR-IOV virtualization, we should
easily be able to test it through VF BAR sizing or explicit flags.

Testing whether we should parse extended capabilities is also pulled
into the function to keep these assumptions in one place.
