Revert "Get rid of _t suffix" In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

/* Define target_phys_addr_t if it exists. */
Hardware convenience library The only target dependency for most hardware is sizeof(target_phys_addr_t). Build these files into a convenience library, and use that instead of building for every target. Remove and poison various target specific macros to avoid bogus target dependencies creeping back in. Big/Little endian is not handled because devices should not know or care about this to start with. Signed-off-by: Paul Brook <paul@codesourcery.com>

Make target_phys_addr_t 64 bits unconditionally The hassle and compile time overhead of maintaining both 32-bit and 64-bit capable source isn't worth the tiny performance advantage which is seen on a minority of configurations. Switch to compiling libhw only once, with target_phys_addr_t unconditionally typedefed to uint64_t. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Split TLB addend and target_phys_addr_t Historically the qemu tlb "addend" field was used for both RAM and IO accesses, so needed to be able to hold both host addresses (unsigned long) and guest physical addresses (target_phys_addr_t). However since the introduction of the iotlb field it has only been used for RAM accesses. This means we can change the type of addend to unsigned long, and remove associated hacks in the big-endian TCG backends. We can also remove the host dependence from target_phys_addr_t.

targphys.h: Define TARGET_PRI*PHYS format specifier macros Define a set of TARGET_PRI*PHYS format specifier macros for working with target_phys_addr_t types. These follow the standard pattern for such macros, and are more flexible than TARGET_FMT_plx, which does not allow specification of field widths.
