2019-10-28translator: add translator_ld{ub,sw,uw,l,q}Emilio G. Cota
We don't bother with replicating the fast path (tlb_hit) of the old cpu_ldst helpers as it has no measurable effect on performance. This probably indicates we should consider flattening the whole set of helpers but that is out of scope for this change.

2019-10-28plugins: implement helpers for resolving hwaddrAlex Bennée
We need to keep a local per-cpu copy of the data as other threads may be running. Currently we can provide insight as to if the access was IO or not and give the offset into a given device (usually the main RAMBlock). We store enough information to get details such as the MemoryRegion which might be useful in later expansions to the API.

2019-10-28plugin-gen: add module for TCG-related codeEmilio G. Cota
We first inject empty instrumentation from translator_loop. After translation, we go through the plugins to see what they want to register for, filling in the empty instrumentation. If if turns out that some instrumentation remains unused, we remove it. This approach supports the following features: - Inlining TCG code for simple operations. Note that we do not export TCG ops to plugins. Instead, we give them a C API to insert inlined ops. So far we only support adding an immediate to a u64, e.g. to count events. - "Direct" callbacks. These are callbacks that do not go via a helper. Instead, the helper is defined at run-time, so that the plugin code is directly called from TCG. This makes direct callbacks as efficient as possible; they are therefore used for very frequent events, e.g. memory callbacks. - Passing the host address to memory callbacks. Most of this is implemented in a later patch though. - Instrumentation of memory accesses performed from helpers. See the corresponding comment, as well as a later patch. Signed-off-by: Emilio G.

2019-10-28riscv/sifive_u: Add L2-LIM cache memoryAlistair Francis
On reset only a single L2 cache way is enabled, the others are exposed as memory that can be used by early boot firmware. This L2 region is generally disabled using the WayEnable register at a later stage in the boot process. To allow firmware to target QEMU and the HiFive Unleashed let's add the L2 LIM (LooselyIntegrated Memory). Ideally we would want to adjust the size of this chunk of memory as the L2 Cache Controller WayEnable register is incremented. Unfortunately I don't see a nice way to handle reducing or blocking out the L2 LIM while still allowing it be re returned to all enabled from a reset.

2019-10-28block: Add @exact parameter to bdrv_co_truncate()Max Reitz
We have two drivers (iscsi and file-posix) that (in some cases) return success from their .bdrv_co_truncate() implementation if the block device is larger than the requested offset, but cannot be shrunk. Some callers do not want that behavior, so this patch adds a new parameter that they can use to turn off that behavior. This patch just adds the parameter and lets the block/io.c and block/block-backend.c functions pass it around. All other callers always pass false and none of the implementations evaluate it, so that this patch does not change existing behavior. Future patches take care of that.

2019-10-25hw/arm/bcm2836: Rename cpus[] as cpu[].corePhilippe Mathieu-Daudé
As we are going to add more core-specific fields, add a 'cpu' structure and move the ARMCPU field there as 'core'.

Connect the recently added SYS_timer. Now U-Boot does not hang anymore polling a free running counter stuck at 0. This timer is also used by the Linux kernel thermal subsystem.

2019-10-25hw/misc/bcm2835_thermal: Add a dummy BCM2835 thermal sensorPhilippe Mathieu-Daudé
We will soon implement the SYS_timer. This timer is used by Linux in the thermal subsystem, so once available, the subsystem will be enabled and poll the temperature sensors. We need to provide the minimum required to keep Linux booting.

2019-10-25virtio: drop unused virtio_device_stop_ioeventfd() functionStefan Hajnoczi
virtio_device_stop_ioeventfd() has not been used since commit 310837de6c1e0badfd736b1b316b1698c53120a7 ("virtio: introduce grab/release_ioeventfd to fix vhost") in 2016. Nowadays ioeventfd is stopped implicitly by the virtio transport when lifecycle events such as the VM pausing or device unplug occur.
