* 'master' of git.qemu-project.org:/pub/git/qemu:
target-mips: Fix incorrect shift for SHILO and SHILOV
target-mips: Fix incorrect code and test for INSV
xilinx_uartlite: Accept input after rx FIFO pop
xilinx_uartlite: suppress "cannot receive message"
xilinx_axienet: Implement R_IS behaviour
The external CPU models were removed on QEMU 1.2, and the support for
the "cpudef" config sections was documented as deprecated, but the
actual removal of the config section was pending.
Now that QEMU 1.3 was released, we can finally kill the support for
cpudef config sections, and support only the built-in CPU models from
target-i386/cpu.c.

I removed the same sort of workaround for OpenBSD within the
configure script with commit 4dcc3f5876
but didn't bother to grep further to come across this same chunk
of code in the curses code itself. So the following diff removes
the same workaround chunk within the curses code.

This patch updates the seabios submodule to commit
b1c35f2b28cc0c94ebed8176ff61ac0e0b377798.
Most important change is that seabios sets the busmaster bit
in the pci config space for the lsi and esp scsi host adapters.
Since commit 1c380f9460 qemu
is strict here and disallows any dma access when the bit is
clear.
