-Subject: [PATCH] qxl_dev: Align QXLRam to 4 bytes
-
-This avoids compilers detect misaligned access which can lead to
-warnings.
-In QEMU the structure is allocated at the beginning of a 4Kb page,
-in Xspice is allocated with a calloc, so the structure will end up 4
-bytes aligned as well with these users. We are not aware of other users
-of QXLRam, but if there was, it's likely the struct would be at least
-naturally aligned, so this change should not impact anyone.
-Aligning to 4 bytes maintains the size of the structure unchanged
-avoiding possible ABI changes.
-clang currently generates an invalid function call if a misaligned
-4 byte atomic operation is detected.
