Handle HKEY event generated on AC power change. The current message asks users to submit data related to this event which leads to a lot of confusion and noise on the mailing list. The following is a list affected models and 'Message-Id' from ibm-acpi-devel@lists.sourceforge.net of people who saw this event when either plugging or unplugging the AC adapter or docking or undocking their laptop.

The call to handlers 0x124 and 0x135 (rfkill control) seems to take a bitmask to control various states of the device. For our rfkill we need a fully on/off. SVZ1311Z9R/X's LTE modem needs more bits up. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=47751Signed-off-by:

The new B series BIOS has version string 43CN46WW. The driver requires that 2nd and 3rd characters be 'E' and 'T' respectively, where as the newer BIOS has 'C' and 'N' respectively. Failing to load the module causes some of the hotkeys to not work.

Found another Lenovo ideapad S205 the product name is 1038DPG, it has a 0x78 EC register exposes the state of wifi hardware switch on the machine. So, add this patch to support Lenovo ideapad S205-1038DPG wifi hardware switch in acer-wmi driver. Evidently the Ideapad S205 is just a model name on the market, but they have totally different product name in DMI table.

For machines with AMD graphic chips, it will send out WMI event and ACPI interrupt at the same time while hitting the hotkey. BIOS will notify the system the next display output mode throught WMI event code, so that windows' application can show an OSD to tell the user which mode will be taken effect. User can hit the display toggle key many times within 2 seconds to choose the mode they want. After 2 seconds, WMI dirver should send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose. And then BIOS will raise another ACPI interrupt to tell the system to really switch the display mode. In Linux desktop, we don't have this kind of OSD to let users to choose the mode they want, so we don't need to call WMIMethod(SDSP) to have another ACPI interrupt. To simplify the problem, we just have to ignore the WMI event, and let the first ACPI interrupt to send out the key event. For the need, here comes another quirk to add machines with this kind of behavior. When the WMI driver receives the display toggle WMI event, and found the machin is in the list, it will do nothing and let ACPI video driver to report the key event. Signed-off-by:

For those machines with wapf=4, BIOS won't update the wireless LED, since wapf=4 means user application will take in chage of the wifi and bt. So, we have to update wlan LED status explicitly. But I found there is another wireless LED bug in launchpad and which is not in the wapf=4 quirk. So, it might be better to set wireless LED status explicitly for all machines.

It is a pity to have MAX_NUMNODES+MAX_NUMNODES tree roots statically allocated, particularly when very few users will ever actually tune merge_across_nodes 0 to use more than 1+1 of those trees. Not a big deal (only 16kB wasted on each machine with CONFIG_MAXSMP), but a pity. Start off with 1+1 statically allocated, then if merge_across_nodes is ever tuned, allocate for nr_node_ids+nr_node_ids. Do not attempt to free up the extra if it's tuned back, that would be a waste of effort. Signed-off-by:

I dislike the way in which "swapcache" gets used in do_swap_page(): there is always a page from swapcache there (even if maybe uncached by the time we lock it), but tests are made according to "swapcache". Rework that with "page != swapcache", as has been done in unuse_pte(). Signed-off-by:
