I am resurrecting an old thread at [1] that tried to introduce named address spaces in asm/percpu.h. The thread ended with the above message [2], but no bugreport was ever filled to GCC's bugzilla. Can please someone from linux community file a PR with a failing testcase to GCC Bugzilla, so we (the GCC community) can analyze the problem and eventually fix the compiler?
