Paolo Bonzini 0c2d70c448 translate-all: ensure host page mask is always extended with 1's ... Anthony reported that >4GB guests on Xen with 32bit QEMU broke after commit 4ed023c ("Round up RAMBlock sizes to host page sizes", 2015-11-05). In that patch sizes are masked against qemu_host_page_size/mask which are uintptr_t, and thus 32bit on a 32bit QEMU, even though the ram space might be bigger than 4GB on Xen. Since ram_addr_t is not available on user-mode emulation targets, ensure that we get a sign extension when masking away the low bits of the address. Remove the ~10 year old scary comment that the type of these variables is probably wrong, with another equally scary comment. The new comment however does not have "???" in it, which is arguably an improvement. For completeness use the alignment macros in linux-user and bsd-user instead of manually doing an &. linux-user and bsd-user are not affected by the Xen issue, however.
