dc9f06ca81 kvm: Pass PCI device pointer to MSI routing functions
In-kernel ITS emulation on ARM64 will require to supply requester IDs.
These IDs can now be retrieved from the device pointer using new
pci_requester_id() function.

This patch adds pci_dev pointer to KVM GSI routing functions and makes
callers passing it.

x86 architecture does not use requester IDs, but hw/i386/kvm/pci-assign.c
also made passing PCI device pointer instead of NULL for consistency with
the rest of the code.

4ca172817a qemu-char: add create to register_char_driver
Having creation as a member of the CharDriver struct removes the need
to export functions for qemu-char.c's usage.  After the conversion,
chardev backends implemented outside qemu-char.c will not need a stub
creation function anymore.

Ultimately all drivers will be converted.  For now, support the case
where cd->create == NULL.

4d9310f427 oslib-win32: only provide localtime_r/gmtime_r if missing
The oslib-win32 file currently provides a localtime_r and
gmtime_r replacement unconditionally. Some versions of
Mingw-w64 would provide crude macros for localtime_r/gmtime_r
which QEMU takes care to disable. Latest versions of Mingw-w64
now provide actual functions for localtime_r/gmtime_r, but
with a twist that you have to include unistd.h or pthread.h
before including time.h.  By luck some files in QEMU have
such an include order, resulting in compile errors:

  CC    util/osdep.o

                 from util/osdep.c:48:

This change adds a configure test to see if localtime_r
exits, and only enables the QEMU impl if missing. We also
re-arrange qemu-common.h try attempt to guarantee that all
source files get unistd.h before time.h and thus see the
localtime_r/gmtime_r defs.

4b3cfe72d9 intc/gic: Extract some reusable vGIC code
Some functions previously used only by vGICv2 are useful also for vGICv3
implementation. Untie them from GICState and make accessible from within
other modules:
- kvm_arm_gic_set_irq()
- kvm_gic_supports_attr() - moved to common code and renamed to
  kvm_device_check_attr()
- kvm_gic_access() - turned into GIC-independent kvm_device_access().
  Data pointer changed to void * because some GICv3 registers are
  64-bit wide

Some of these changes are not used right now, but they will be helpful for
implementing live migration.

Actually kvm_dist_get() and kvm_dist_put() could also be made reusable, but
they would require two extra parameters (s->dev_fd and s->num_cpu) as well as
lots of typecasts of 's' to DeviceState * and back to GICState *. This makes
the code very ugly so i decided to stop at this point. I tried also an
approach with making a base class for all possible GICs, but it would contain
only three variables (dev_fd, cpu_num and irq_num), and accessing them through
the rest of the code would be again tedious (either ugly casts or qemu-style
separate object pointer). So i disliked it too.

197e35249a kvm-all.c: add qemu_irq/gsi hash table and utility routines
VFIO platform device needs to setup irqfd but it does not know the
gsi corresponding to the device qemu_irq. This patch proposes to
store a hash table in kvm_state using the qemu_irq as key and the gsi
as a value.

kvm_irqchip_set_qemuirq_gsi allows to insert such a pair. The interrupt
controller is supposed to use it.

kvm_irqchip_[add, remove]_irqfd_notifier allows to setup/tear down
irqfd directly from the qemu_irq.

04e00c92ef monitor: Use trad. command interface for HMP pcie_aer_inject_error
All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one.  Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.

pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print().  The
former is a peculiar crossbreed between HMP and QMP handler.  On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0.  Printing the QDict is left to
pcie_aer_inject_error_print().  On failure, it works more like an HMP
handler: print error to monitor, return negative number.

To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error().  By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

For drive_del, that's easy: hmp_drive_del() sheds its unused last

116694c34a Extend TPM TIS interface to support TPM 2
Following the recent upgrade to version 1.3, extend the TPM TIS
interface with capabilities introduced for support of a TPM 2.

TPM TIS for TPM 2 introduced the following extensions beyond the
TPM TIS 1.3 (used for TPM 1.2):

- A new 32bit interface Id register was introduced.
- New flags for the status (STS) register were defined.
- New flags for the capability flags were defined.

Support the above if a TPM TIS 1.3 for TPM 2 is used with a TPM 2
on the backend side. Support the old TPM TIS 1.3 configuration if a
TPM 1.2 is being used. A subsequent patch will then determine which
TPM version is being used in the backend.

The lack of ffs(3) in the MinGW headers is a hint that we shouldn't rely
on it.  MinGW 4.9.2 does not make it available for linking when QEMU's
./configure --enable-debug is used (release builds are fine though).

Now that all QEMU code has been switched to ctz32() there is no need for
ffs(3).
