The buildbot shows these compiler warnings: block/vvfat.c: In function 'create_short_and_long_name': block/vvfat.c:620: warning: array size (8) smaller than bound length (11) block/vvfat.c:620: warning: array size (8) smaller than bound length (11) block/vvfat.c:635: warning: array size (8) smaller than bound length (11) block/vvfat.c:635: warning: array size (8) smaller than bound length (11) They are caused by tricky code where 8 characters for the name are followed by 3 characters for the extension, and some operations touch both name and extension. Using an 11 character name which includes the extension fixes the compiler warning, satisfies cppcheck, valgrind and maybe other static and dynamic code checkers, and even simplifies some parts of the code.

2013-12-10tcg: Use bitmaps for free temporariesRichard Henderson
We previously allocated 32-bits per temp for the next_free_temp entry. We now allocate 4 bits per temp across the 4 bitmaps. Using a linked list meant that if a translator is tweeked, resulting in temps being freed in a different order, that would have follow-on effects throughout the TB. Always allocating the lowest free temp means that follow-on effects are minimized, which can make it easier to diff output when debugging the translators.

2013-12-10target-arm: Allow secondary KVM CPUs to be booted via PSCIPeter Maydell
New ARM boards are generally expected to boot their secondary CPUs via the PSCI interface, rather than ad-hoc "loop around in holding pen code" as hw/arm/boot.c implements. In particular this is necessary for mach-virt kernels. For KVM we achieve this by creating the VCPUs with a feature flag marking them as starting in PSCI powered-down state; the guest kernel will then make a PSCI call (implemented in the host kernel) to start the secondaries at an address of its choosing once it has got the primary CPU up. Implement this setting of the feature flag, controlled by a qdev property for ARMCPU, which board code can set if it is a PSCI system.

2013-12-10device_tree.c: Terminate the empty reservemap in create_device_tree()Peter Maydell
Device trees created with create_device_tree() may not have any entries in their reservemap, because the FDT API requires that the reservemap is completed before any FDT nodes are added, and create_device_tree() itself creates a node. However we were not calling fdt_finish_reservemap(), which meant that there was no terminator in the reservemap list and whatever happened to be at the start of the FDT data section would end up being interpreted as reservemap entries. Avoid this by calling fdt_finish_reservemap() to add the terminator.

2013-12-10target-arm: Provide mechanism for getting KVM constants even if not CONFIG_KVMPeter Maydell
There are a number of places where it would be convenient for ARM code to have working definitions of KVM constants even in code which is compiled with CONFIG_KVM not set. In this situation we can't simply include the kernel KVM headers (which might conflict with host header definitions or not even compile on the compiler we're using) so we have to redefine equivalent constants. Provide a mechanism for doing this and checking that the values match, and use it for the constants we're currently exposing via an ad-hoc mechanism.

To make it consistent for easier code reading. The order in which variables are defined and functions are called is set to match the address map ordering. The new consistent order of doing stuff is: SCU -> GIC -> MPTimer -> WDT. 0 functional change.
