2013-02-01linux-user: bsd-user: Don't reset X86CPU twiceAndreas Färber2-2/+2
Since commit 65dee38052597b6285eb208125369f01b29ba6c1 (target-i386: move cpu_reset and reset callback to cpu.c) the x86 CPU is reset through cpu_init() but was still reset immediately after in linux-user and bsd-user. Clean this up. Similarly in linux-user/syscall.c it is also reset after cpu_copy(). But that's a bug of its own, fixing which poses a semantic change.

2013-02-01target-unicore32: Rename CPU subtypesAndreas Färber2-3/+7
In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. No functional changes for -cpu arguments.

2013-02-01target-openrisc: TYPE_OPENRISC_CPU should be abstractAndreas Färber1-1/+1
A basic assumption of CPU subtypes is that only specific models get instantiated. A user is not supposed to instantiate an <arch>-cpu. Suppress it via abstract = true, which also drops or32-cpu from -cpu ? output. Cc: qemu-stable@nongnu.org Cc: Jia Liu <proljc@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a hw_error().

2013-01-31target-mips: Sign-extend the result of LWRRichard Sandiford1-0/+1
Sign-extend the result of LWR, as is already done for LWL. This is necessary in the case where LWR loads the full word (i.e. the address is actually aligned). In the other cases, it is implementation defined whether the upper 32 bits of the result are unchanged or a copy of bit 31. The latter seems easier to implement. Previously the code used: (oldval & (0xfffffffe << (31 - bitshift))) | (newval >> bitshift) which zeroed the upper bits of the register, losing any previous sign extension in the unaligned cases.
