2014-02-28qmp: Check for returned data from __json_read in get_eventsFam Zheng
When QEMU process aborts and socket is closed, qmp client will not detect it. When this happens, some qemu-iotests scripts will enter an endless loop waiting for qmp events. It's better we raise an exception in qmp.py to catch this and make the test script stop.

Make monitor command 'dump-guest-memory' be able to dump in kdump-compressed format. The command's usage: dump [-p] protocol [begin] [length] [format] 'format' is used to specified the format of vmcore and can be: 1. 'elf': ELF format, without compression 2. 'kdump-zlib': kdump-compressed format, with zlib-compressed 3. 'kdump-lzo': kdump-compressed format, with lzo-compressed 4. 'kdump-snappy': kdump-compressed format, with snappy-compressed Without 'format' being set, it is same as 'elf'. And if non-elf format is specified, paging and filter is not allowed. Note: 1. The kdump-compressed format is readable only with the crash utility and makedumpfile, and it can be smaller than the ELF format because of the compression support. 2. The kdump-compressed format is the 6th edition.

2014-02-26target-arm: Add utility function for checking AA32/64 state of an ELPeter Maydell
There are various situations where we need to behave differently depending on whether a given exception level is in AArch64 or AArch32 state. The state of the current exception level is stored in env->aarch64, but there's no equivalent guest-visible architected state bits for the status of the exception levels "above" the current one which may still affect execution. At the moment we only support EL1 (ie no EL2 or EL3) and insist that AArch64 capable CPUs run with EL1 in AArch64 state, but these may change in the future, so abstract out the "what state is this?" check into a utility function which can be enhanced later if necessary.

2014-02-26target-arm: Store AIF bits in env->pstate for AArch32Peter Maydell
To avoid complication in code that otherwise would not need to care about whether EL1 is AArch32 or AArch64, we should store the interrupt mask bits (CPSR.AIF in AArch32 and PSTATE.DAIF in AArch64) in one place consistently regardless of EL1's mode. Since AArch64 has an extra enable bit (D for debug exceptions) which isn't visible in AArch32, this means we need to keep the enables in env->pstate. (This is also consistent with the general approach we're taking that we handle 32 bit CPUs as being like AArch64/ARMv8 CPUs but which only run in 32 bit mode.)

2014-02-26target-arm: Implement AArch64 OSLAR_EL1 sysreg as WIPeter Maydell
Define a dummy version of the AArch64 OSLAR_EL1 system register which just ignores writes. Linux will always write to this (it is the OS lock used for debugging), but we don't support debug.

2014-02-26target-arm: Implement AArch64 dummy breakpoint and watchpoint registersPeter Maydell
In AArch64 the breakpoint and watchpoint registers are mandatory, so the kernel always accesses them on bootup. Implement dummy versions, which read as written but have no actual effect.

2014-02-26target-arm: Implement AArch64 ID and feature registersPeter Maydell
Implement the AArch64-specific ID and feature registers. Although many of these are currently not used by the architecture (and so always zero for all implementations), we define the full set of fields in the ARMCPU struct for symmetry.
