2017-01-24migration: extend VMStateInfoJianjun Duan1-4/+10
Current migration code cannot handle some data structures such as QTAILQ in qemu/queue.h. Here we extend the signatures of put/get in VMStateInfo so that customized handling is supported. put now will return int type.

2017-01-13cputlb: drop flush_global flag from tlb_flushAlex Bennée3-8/+8
We have never has the concept of global TLB entries which would avoid the flush so we never actually use this flag. Drop it and make clear that tlb_flush is the sledge-hammer it has always been.

2017-01-13qom/cpu: move tlb_flush to cpu_common_resetAlex Bennée2-2/+4
It is a common thing amongst the various cpu reset functions want to flush the SoftMMU's TLB entries. This is done either by calling tlb_flush directly or by way of a general memset of the CPU structure (sometimes both). This moves the tlb_flush call to the common reset function and additionally ensures it is only done for the CONFIG_SOFTMMU case and when tcg is enabled. In some target cases we add an empty end_of_reset_fields structure to the target vCPU structure so have a clear end point for any memset which is resetting value in the structure before CPU_COMMON (where the TLB structures are). While this is a nice clean-up in general it is also a precursor for changes coming to cputlb for MTTCG where the clearing of entries can't be done arbitrarily across vCPUs. Currently the cpu_reset function is usually called from the context of another vCPU as the architectural power up sequence is run. By using the cputlb API functions we can ensure the right behaviour in the future.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth19-0/+38839
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.
