* [PATCH] x86_64: Disable ACPI blacklist by year for now on x86-64Andi Kleen2006-02-26
| | | | | | | | | | | | | | | | | ACPI is initialized very early on x86-64, before the DMI code is initialized. This means it would often discover a 0 year and then turn off ACPI because it thought the BIOS was too old. Some systems don't boot without ACPI so this was a problem. I have a full fix by adding new very early DMI detection, but it needs more testing before it can be merged. For 2.6.16 let's just turn the check off. It never made much sense anyways because there are no x86-64 systems older than 2002 or so and they generally all have working ACPI.

* [PATCH] x86-64/i386: Use common X86_PM_TIMER option and make it EMBEDDEDAndi Kleen2006-02-26
| | | | | | | | | | | | | | | | This makes x86-64 use the common X86_PM_TIMER Kconfig entry in drivers/acpi And since PM timer is needed for correct timing on a lot of systems now (e.g. AMD dual cores) and we often get bug reports from people who forgot to set it make it depend on CONFIG_EMBEDDED. x86-64 had this change before and it's a good thing. I also fixed the description slightly to make this more clear. Cc: len.brown@intel.com Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EGA boards suck: they mostly have write-only registers. This is particularly problematic for the overflow register: for being able to write to it, we would have to handle vertical sync & such too, which (I'd say) would potentially break a lot of configurations. Instead, just disabling vertical resize for EGA boards is just nice enough (horizontal resize still works).

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tty_schedule_flip() would schedule a thread that would call flush_to_ldisc(). If tty_buffer_request_room() gets called prior to that thread running -- which is likely in this loop in hvc_poll(), it would set the active flag in the tty buffer and consequently flush_to_ldisc() would ignore it. The result is that input on the hvc console is not processed. This fix calls tty_flip_buffer_push (and flags the tty as "low_latency"). The push to the ldisc thus happens synchronously.

* | | sbp2: variable status FIFO address (fix login timeout)Stefan Richter2006-02-23

Since the core only selects addresses which are guaranteed to be out of the "physical range" as per OHCI 1.1, this patch also fixes an old bug: OHCI controllers which implement a writeable PhysicalUpperBound register included sbp2's status FIFO in the physical range. That way sbp2 was never notified of a succesful login and always failed after timeout. Affected OHCI host adapters include ALi and Fujitsu controllers. As another side effect of this patch, the status FIFO is no longer located in a range for which OHCI chips perform "posted writes". Each status write now requires a response subaction. But since large data transfers involve only few status writes, there is no measurable decrease of I/O throughput. What's more, the status FIFO is now safe from potential host bus errors. Nevertheless, posted writes could be re-enabled by extensions to the ARM features of the 1394 stack.
