On a real hardware changing read-only bits has no effect
Use a mask common for SCSI and Ethernet registers. The crucial
bit is DMA_INTR, because setting or clearing it may produce
spurious interrupts.

The 'tarbin' Makefile rule doesn't include qemu-system-sparc64, but
should do, now that sparc64-softmmu is in the default target list.
The rule attempts to tar up binaries that were not built if a target
list was passed to the configure script -- in which case, it will
either fail, or otherwise include binaries from previous builds.
Fix both problems once and for all by building a list of binaries to
include in the tarball, using the list of targets to be built.

This seems to resolve subtle breakages of our build system:
Dependency files generated for targets like 'dir/foo.o' were saved as
'foo.d'. Now, if there was also a target 'foo.o', one of the dependency
file was overwritten. Concrete example: libhw*/macio.o vs.
libhw*/ide/macio.o. And this often left a segfaulting build result
behind when changing the "wrong" data structures".
Fix it by generating proper 'dir/foo.d'.

they can be modified by called functions.

Alpha passes oldset by value in a register, and returns the newset
as the return value; as compared to the standard implementation in
which both are passed by reference. This requires being able to
distinguish negative return values that are not errors. Do this in
the same way as the Alpha Linux kernel, by storing a zero in V0 in
the implementation of the syscall.
At the same time, fix a think-o in the regular sigprocmask path in
which we passed the target, rather than the host, HOW value.

Add more OPC values, and tgen_arithr. Use the later throughout.
Note that normal reg/reg arithmetic now uses the Gv,Ev opcode form
instead of the Ev,Gv opcode form used previously. Both forms
disassemble properly, and so there's no visible change when diffing
log files before and after the change. This change makes the operand
ordering within the output routines more natural, and avoids the need
to define an OPC_ARITH_EvGv since a read-modify-write with memory is
not needed within TCG.

In oneshot mode, the delta needs to come from the TimerLoad register,
not the maximum limit.
Signed-off-by: Rabin Vincent <rabin@rab.in>
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
Reload the timer when TimerControl is written, if the timer is to be
enabled. Otherwise, if an earlier write to TimerLoad was done while
periodic mode was not set, s->delta may incorrectly still have the value
of the maximum limit instead of the value written to TimerLoad.
This problem is evident on versatileap on current linux-next, which
enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling
periodic mode and starting the timer. This causes the first periodic
tick to be scheduled to occur after 0xffffffff periods, leading to a
perceived hang while the kernel waits for the first timer tick.
