Move virt's PSCI DT fixup code to arm/boot.c and set this fixup to happen automatically for every board that doesn't mark "psci-conduit" as disabled. This way emulated boards other than "virt" that rely on PSIC for SMP could benefit from that code.

2018-02-09target/arm: Make v7M exception entry stack push check MPUPeter Maydell
The memory writes done to push registers on the stack on exception entry in M profile CPUs are supposed to go via MPU permissions checks, which may cause us to take a derived exception instead of the original one of the MPU lookup fails. We were implementing these as always-succeeds direct writes to physical memory. Rewrite v7m_push_stack() to do the necessary checks.

2018-02-09target/arm: Add ignore_stackfaults argument to v7m_exception_taken()Peter Maydell
In the v8M architecture, if the process of taking an exception results in a further exception this is called a derived exception (for example, an MPU exception when writing the exception frame to memory). If the derived exception happens while pushing the initial stack frame, we must ignore any subsequent possible exception pushing the callee-saves registers. In preparation for making the stack writes check for exceptions, add a return value from v7m_push_stack() and a new parameter to v7m_exception_taken(), so that the former can tell the latter that it needs to ignore failures to write to the stack. We also plumb the argument through to v7m_push_callee_stack(), which is where the code to ignore the failures will be. (Note that the v8M ARM pseudocode structures this slightly differently: derived exceptions cause the attempt to process the original exception to be abandoned; then at the top level it calls DerivedLateArrival to prioritize the derived exception and call TakeException from there. We choose to let the NVIC do the prioritization and continue forward with a call to TakeException which will then take either the original or the derived exception. The effect is the same, but this structure works better for QEMU because we don't have a convenient top level place to do the abandon-and-retry logic.)

2018-02-09target/arm: Split "get pending exception info" from "acknowledge it"Peter Maydell
Currently armv7m_nvic_acknowledge_irq() does three things: * make the current highest priority pending interrupt active * return a bool indicating whether that interrupt is targeting Secure or NonSecure state * implicitly tell the caller which is the highest priority pending interrupt by setting env->v7m.exception We need to split these jobs, because v7m_exception_taken() needs to know whether the pending interrupt targets Secure so it can choose to stack callee-saves registers or not, but it must not make the interrupt active until after it has done that stacking, in case the stacking causes a derived exception. Similarly, it needs to know the number of the pending interrupt so it can read the correct vector table entry before the interrupt is made active, because vector table reads might also cause a derived exception. Create a new armv7m_nvic_get_pending_irq_info() function which simply returns information about the highest priority pending interrupt, and use it to rearrange the v7m_exception_taken() code so we don't acknowledge the exception until we've done all the things which could possibly cause a derived exception.

2018-02-09target/arm: Add armv7m_nvic_set_pending_derived()Peter Maydell
In order to support derived exceptions (exceptions generated in the course of trying to take an exception), we need to be able to handle prioritizing whether to take the original exception or the derived exception. We do this by introducing a new function armv7m_nvic_set_pending_derived() which the exception-taking code in helper.c will call when a derived exception occurs. Derived exceptions are dealt with mostly like normal pending exceptions, so we share the implementation with the armv7m_nvic_set_pending() function. Note that the way we structure this is significantly different from the v8M Arm ARM pseudocode: that does all the prioritization logic in the DerivedLateArrival() function, whereas we choose to let the existing "identify highest priority exception" logic do the prioritization for us. The effect is the same, though.

The x86 vector instruction set is extremely irregular. With newer editions, Intel has filled in some of the blanks. However, we don't get many 64-bit operations until SSE4.2, introduced in 2009. The subsequent edition was for AVX1, introduced in 2011, which added three-operand addressing, and adjusts how all instructions should be encoded. Given the relatively narrow 2 year window between possible to support and desirable to support, and to vastly simplify code maintainence, I am only planning to support AVX1 and later cpus.

To make our efforts on QEMU testing easier to consume by contributors, let's add a document. For example, Patchew reports build errors on patches that should be relatively easy to reproduce with a few steps, and it is much nicer if there is such a documentation that it can refer to. This focuses on how to run existing tests and how to write new test cases, without going into the frameworks themselves. The VM based testing section is moved from tests/vm/README which now is a single line pointing to the new doc.
