2017-01-10tcg: Allow an operand to be matching or a constantRichard Henderson
This allows an output operand to match an input operand only when the input operand needs a register. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>
2017-01-10tcg: Pass the opcode width to target_parse_constraintRichard Henderson
This will let us choose how to interpret a given constraint depending on whether the opcode is 32- or 64-bit. Which will let us share more constraint combinations between opcodes. At the same time, change the interface to return the advanced pointer instead of passing it in/out by reference.

Move DIMM devices from global _SB scope to a new \_SB.MHPC container along with common methods used by DIMMs: MCRS, MRST, MPXM, MOST, MEJ00, MSCN, MTFY this reduces AML size on 12 * #slots bytes, i.e. up to 3072 bytes for 265 slots.

2017-01-10memhp: don't generate memory hotplug AML if it's not enabled/supportedIgor Mammedov
That reduces DSDT by 910 bytes when memory hotplug isn't enabled. While doing so drop intermediate variables/arguments passing around ACPI_MEMORY_HOTPLUG_IO_LEN and making it local to memory_hotplug.c, hardcoding it there as it can't change. Also don't pass around ACPI_MEMORY_HOTPLUG_BASE through intermediate variables/arguments where it's not needed. Instead initialize in module static variable when MMIO region is mapped and use that within memory_hotplug.c whenever it's required. That way MMIO base specified only at one place and AML with MMIO would always use the same value. Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

since static and dynamic parts of memory MHPD device are now in the same table (DSDT), there is no point keeping them scattered across the table, so consolidate it in one place.
