1358681344 tci: Fix build breakage (unresolved symbol tcg_out_tb_finalize)
Commit 32761257c0 enabled
qemu_ld/st optimization unconditionally for some hosts.

The TCG interpreter still does not support this kind of
optimization. Therefore builds with TCI fail with an
unresolved symbol tcg_out_tb_finalize. This is fixed here.

de91f53799 tci: fix build breakage for target MIPS
commit 5f7319cd introduced GETPC() usage for MIPS, which is currently
not defined when building with --enable-tcg-interpreter. Add MIPS to
the list of targets we selectively define GETPC() for.

3bc2f570ec build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.

This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file.  Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).

Thus, all stubs are placed in separate object files and put together in
a static library.  The library then is linked to all programs.

df9ffb726f vga: fix bochs alignment issue
The bochs dispi interface traditionally uses port 0x1ce as 16bit index
register and port 0x1cf as 16bit data register.  The later is unaligned,
and probably for that reason the the data register was moved to 0x1d0
for non-x86 archs.

This patch makes the data register available at 0x1d0 on x86 too.  The
old x86 location is kept for compatibility reasons, so both 0x1cf and
0x1d0 can be used as data register on x86.

68d001928b mips/malta: fix CBUS UART interrupt pin
According to the MIPS Malta Developement Platform User's Manual, the
i8259 interrupt controller is supposed to be connected to the hardware
IRQ0, and the CBUS UART to the hardware interrupt 2.

In QEMU they are both connected to hardware interrupt 0, the CBUS UART
interrupt being wrong. This patch fixes that. It should be noted that
the irq array in QEMU includes the software interrupts, hence
env->irq[2] is the first hardware interrupt.

e1d1e5867d vfio-pci: Add KVM INTx acceleration
This makes use of the new level irqfd support enabling bypass of qemu
userspace both on INTx injection and unmask.  This significantly
boosts the performance of devices making use of legacy interrupts (ex.
~60% better netperf TCP_RR scores for an e1000e assigned to a Linux
guest and booted with pci=nomsi).  This also avoids flipping mmaps on
and off to simulate EOIs, so greatly improves performance of device
access in addition to interrupt latency.
