Switch all task workers to a private thinkpad-acpi workqueue. This way, we don't risk causing trouble for other tasks scheduled to the default work queue, as our workers end up needing to access the ACPI EC, run ACPI AML code, trigger SMI traps... and none of those are exactly known to be fast, simple operations.

Unfortunately, a lot of stuff in the kernel has size limitations, so "thinkpad-acpi" ends up eating up too much real estate. We were using "tpacpi" in symbols already, but this shorthand was not visible to userland. Document that the driver will use tpacpi as a short hand where necessary, and use it to name the kernel thread for NVRAM polling (now named "ktpacpi_nvramd"). Also, register a module alias with the shorthand. One can refer to the module using the shorthand name. Signed-off-by:

ibm-acpi and thinkpad-acpi did not know about bit 5 of the EC backlight level control register (EC 0x31), so it was always forced to zero on any writes. This would disable the BIOS option to *not* use a dimmer backlight level scale while on battery, and who knows what else (there are two other control bits of unknown function). Bit 5 controls the "reduce backlight levels when on battery" optional functionality (active low). Bits 6 and 7 are better left alone as well, instead of being forced to zero. Signed-off-by:

If userspace applications mess with the CMOS NVRAM, or something causes both the ACPI firmware and thinkpad-acpi to try to change the brightness at the same time, it is possible to have the CMOS and EC registers for the current brightness go out of sync. Should that happen, thinkpad-acpi could be really obnoxious when using a brightness_mode of 3 (both EC and CMOS). Instead of complaining a massive number of times, make sure to complain only once until EC and CMOS are back in sync. Signed-off-by:

During initialization, thinkpad-acpi outputs some messages to make sure releavant box identification information is easily available in-line with the rest of the driver messages. Enhance those messages to output the alfanumeric model number as well. Signed-off-by:

thinkpad-acpi knows for a while now how to best program the hotkeys by default, and always enable them by default. Unfortunately, this information has not filtered down everywhere it needs to, yet. Notably, old ibm-acpi documentation and most "thinkpad setup guides" will have wrong information on this area. Warn the local admin once whenever any of the following patterns are met: 1. Attempts to set hotkey mask to 0xffff (artifact from docs and config for the old ibm-acpi driver and behaviour). This mask makes no real-world sense; 2. Attempts to set hotkey mask to 0xffffffff, which means the user is trying to just have "everything work" without even reading the documentation, or that we need to get a bug report, because there is a new thinkpad out there with new exciting hot keys :-) 3. Attempts to set hotkey mask to 0xffffff, which is almost never the correct way to set up volume and brightness event reporting (and with the current state-of-the-art, it is known to never be right way to do it). The driver will perform any and all requested operations, though, regardless of any warnings. I hope these warnings can be removed one or two years from now. Signed-off-by:

Lenovo ThinkPads with generic ACPI backlight level control can be easily set to react to keyboard brightness key presses in a more predictable way than what they do when in "DOS / bootloader" mode after Linux brings up the ACPI interface. The switch to the ACPI backlight mode in the firmware is designed to be safe to use only as an one way trapdoor. One is not to force the firmware to switch back to "DOS/bootloader" mode except by rebooting. The mode switch itself is performed by calling any of the ACPI _BCL methods at least once. When in ACPI mode, the backlight firmware just issues (standard) events for the brightness up/down hot key presses along with the non-standard HKEY events which thinkpad-acpi traps, and doesn't touch the hardware. thinkpad-acpi will: 1. Place the ThinkPad firmware in ACPI backlight control mode if one is available 2. Suppress HKEY backlight change notifications by default to avoid double-reporting when ACPI video is loaded when the ThinkPad is in ACPI backlight control mode 3. Urge the user to load the ACPI video driver The user is free to use either the ACPI video driver to get the brightness key events, or to override the thinkpad-acpi default hotkey mask to get them from thinkpad-acpi as well (this will result in duplicate events if ACPI video is loaded, so let's hope distros won't screw this up). Provided userspace is sane, all should work (and *keep* working), which is more that can be said about the non-ACPI mode of the new Lenovo ThinkPad BIOSes when coupled to current userspace and X.org drivers. Full guidelines for backlight hot key reporting and use of the thinkpad-acpi backlight interface have been added to the documentation. Signed-off-by:

Fix 18 errors and several warnings given by checkpatch.pl: - use of C99 // comments; - trailing whitespace; - 'switch' and 'case' not at the same indentation level; - no space before the open parenthesis of the 'if' and 'switch' statements; - space between function name and open parenthesis (though I have introduced such warnins in some places since the code looks prettier with the spaces); - including <asm/io.h> instead of <linux/io.h>; - line over 80 characters. In addition to these changes, also do the following: - make the arrays in sil_set_pio_mode() 'static', and make the arrays in sil_set_dma_mode() 'static const'; - change the string of the 'if' statements into the 'switch' statement in sil_pata_udma_filter(); - drop the needless '==' operators from the 'if' statements where a condition is a mere bit test; - remove needless initializer for the 'tmp' variable in init_chipset_siimage(); - beautify groups of the variable initializers and assignment operators; - add new line after variable definitions; - remove new line between the comment and the statements it refers to; - remove needless curly braces and parentheses; - fix typos, capitalize acronyms, etc. in the comments...

It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the availability of an asm/ide.h It turns out this was done for ARM, and we can simply always select HAVE_IDE on ARM instead of manually tracking which platforms might possible have an IDE controller directly or indirectly.
