[PULL 21/30] target/alpha: Do not use target_ulong for page table entries / indexes

Posted by Philippe Mathieu-Daudé 3 days, 14 hours ago

%L[123]pte are loaded calling ldq_le_phys() which returns
a uint64_t. %pt is loaded with @ptbr, declared as uint64_t
in target/alpha/cpu.h:

  236    uint64_t ptbr;

%index is at most 1024 so can fit in uint16_t.
