During savevm, the VM state is written to the active L1 of the image and then a snapshot is taken. After that, the VM state isn't needed any more in the active L1 and should be discarded. This is implemented by this patch. The impact of not discarding the VM state is that a snapshot can never become smaller than any previous snapshot (because it would be padded with old VM state), and more importantly that future savevm operations cause unnecessary COWs (with associated flushes), which makes subsequent snapshots much slower.

For newer target architectures, glibc can be picky about the kernel version: for example, it will not run on an aarch64 system unless the kernel reports itself as at least 3.8.0. Accommodate this by enhancing the existing support for faking the kernel version so that each target can optionally specify a minimum version: if the user doesn't force a specific fake version then we will override with the minimum required version only if the real host kernel version is insufficient. Use this facility to let aarch64 report a minimum of 3.8.0. Signed-off-by: NPeter Maydell <peter.maydell@linaro.org> Message-id: 1378235544-22290-21-git-send-email-peter.maydell@linaro.org

Add the main linux-user cpu loop for AArch64. Since AArch64 has a different system call interface, doesn't need to worry about FPA emulation and may in the future keep the prefetch/data abort information in different system registers, it's simplest just to use a completely separate loop from the 32 bit ARM target, rather than peppering it with ifdefs.

We should translate AArch64 mode separately from AArch32 mode. In AArch64 mode, registers look vastly different, instruction encoding is completely different, basically the system turns into a different machine. So let's do a simple if() in translate.c to decide whether we can handle the current code in the legacy AArch32 code or in the new AArch64 code.
