b3e5759e09 usb-musb: uninline functions
Prototype without "inline" keyword breaks the build with some gcc
versions.  Noticed by Alexander Graf.

Fix this by removing the inline keywork everywhere.  Some functions
can't be inlined anyway as the are referenced using function pointers.
Beside that gcc does a pretty good job on auto-inlining these days.

432d268c05 xen: Introduce the Xen mapcache
On IA32 host or IA32 PAE host, at present, generally, we can't create
an HVM guest with more than 2G memory, because generally it's almost
impossible for Qemu to find a large enough and consecutive virtual
address space to map an HVM guest's whole physical address space.
The attached patch fixes this issue using dynamic mapping based on
little blocks of memory.

Each call to qemu_get_ram_ptr makes a call to qemu_map_cache with the
lock option, so mapcache will not unmap these ram_ptr.

Blocks that do not belong to the RAM, but usually to a device ROM or to
a framebuffer, are handled in a separate function. So the whole RAMBlock
can be map.
