2017-05-12target/s390x: Implement LOAD PROGRAM PARAMETERMiroslav Benes1-0/+2
Linux arch/s390/kernel/head(64).S uses LPP instruction if it is available in facilities list provided by stfl/stfle instruction. This is the case of newer z/System generations and their qemu definition. The description of LPP is at http://www-01.ibm.com/support/docview.wss?uid=isg26fcd1cc32246f4c8852574ce0044734a Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Miroslav Benes <mbenes@suse.cz> Message-Id: <20170227085353.20787-1-mbenes@suse.cz> Signed-off-by: Richard Henderson <rth@twiddle.net>

At the same time, improve STORE FACILITIES LIST so that we don't hard-code the list for all cpus. Signed-off-by: Richard Henderson <rth@twiddle.net>
2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-0/+931
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
