2017-01-10memhp: consolidate scattered MHPD device declarationIgor Mammedov1-63/+60
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. There aren't any functional change, only AML text movement from externally refferenced MHPD scope directly into MHPD device declaration.

Commit 35c5a52d "acpi: do not use TARGET_PAGE_SIZE" changed struct NvdimmDsmIn from a variable-size structure to a fixed-size structure of 4096 bytes. It forgot to adjust an assert in nvdimm_dsm_set_label_data(..., NvdimmDsmIn *in, ...): assert(sizeof(*in) + sizeof(*set_label_data) + set_label_data->length <= 4096); which could crash QEMU when guest writes NVDIMM labels.

The buffer is used to save the FIT info for all the presented nvdimm devices which is updated after the nvdimm device is plugged or unplugged. In the later patch, it will be used to construct NVDIMM ACPI _FIT method which reflects the presented nvdimm devices after nvdimm hotplug As FIT buffer can not completely mapped into guest address space, OSPM will exit to QEMU multiple times, however, there is the race condition - FIT may be changed during these multiple exits, so that some rules are introduced: 1) the user should hold the @lock to access the buffer and 2) mark @dirty whenever the buffer is updated. @dirty is cleared for the first time OSPM gets fit buffer, if dirty is detected in the later access, OSPM will restart the access As fit should be updated after nvdimm device is successfully realized so that a new hotplug callback, post_hotplug, is introduced Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.
