On 32bit qemu-user targets, memory allocation failed after about 2GB due to incorrect
signed (instead of the correct unsigned) "last" parameter in pageflags_find and
pageflags_next functions (file accel/tcg/user-exec.c).
The parameter, on 32bit targets, will be signed-extent to the 64bit final uint64_t
parameters, leading to incorrect comparison on the RBTree (only the first call to mmap on
the upper 2GB memory will be successful).

Don't reply to previous patches with a new patch -- tooling doesn't handle it.
I've applied this by hand.
