Dear Alexander Holler,

Beeing kind of a defensive programmer, I still would prefer to use have that __asm__ for write* too. That would at least prevent us from a possible bug there too.
So why don't you simply test and, assuming it's working, ACK the patch I submitted yesterday? We should be on the safe side, then, and don't have to care about which mood the current compiler's optimizer might be in or what the POM is.
Sorry, I haven't had your last patch (mail) before I've written the mail you are referencing.
I have updated my mail-system at home (armv5 with 128mb ram) and the incoming queue, mainly filled through lkml, is still not completly processed. ~2000 messages (3 days) need some time to go through spamassassin on such a low-level hardware. ;)
I've seen you've switched from do {} while() to "something else", but I can't comment on that "something else". Because I've already switched to 4.5.2. I'll have to dig out a system where I have a 4.5.1 to test the problem occured with the write. If anybody else already has tested it, I'm fine with it.
Regards,
Alexander
