A few models offer the chance to set whether to resume from S3 and/or S4 when opening the lid. [malattia@linux.it: create three sysfs files for S3/4/5 rather than using a single one accepting a bitmask. Support S5 since the DSDT exports it. Use a struct to hold all the related values, caching of the current status value rather than re-reading all the time in the sysfs show function.] Signed-off-by:

Loop through the list of SNC handles and run the proper initialization function for each of the known handles. Also return void in function where we are not checking the return value anyway. For notifications we also know which handle is linked to the event and the code becomes simpler to read with a switch rather than using convoluted ifs. [malattia@linux.it: Code reworked to merge the initialization code improvements and the notify callback changes. Modified the code paths to allow easier error exit paths. Also fixed some missing break statements and spelling mistakes.] Signed-off-by:

All calls into the SNC device methods have zero or one arguments and return an integer or a buffer (some functions go as far as returning an integer _or_ a buffer depending on the input parameter...). This allows simplifying a couple of code paths and prepares the field for other users of functions returning buffers. Signed-off-by:

Some Toshiba laptops have the transflective LCD and toshset can control its backlight state. I brought this feature to the mainline. To support transflective LCD, it's implemented by adding an extra level to the backlight and having 0 change to transflective mode. It was tested on a Toshiba Portege R500. Signed-off-by:

Currently the backlight device is registered unconditionally, but many (probably most) Toshibas either don't support HCI_LCD_BRIGHTNESS or only support reading from it. This patch adds a test of HCI_LCD_BRIGHTNESS during initialization and only registers the backlight device if this interface supports both reads and writes.

The tp_features.bright_acpimode will not be set correctly for brightness control because ACPI_VIDEO_HID will not be located in ACPI. As a result, a duplicated key event will always be sent. acpi_video_backlight_support() is sufficient to detect standard ACPI brightness control. Signed-off-by:

Daniel Drake authored
The XO-1 rfkill driver should only send EC commands when changing between blocked/unblocked state. The rfkill switch is asked to be unblocked on every resume (even when the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET command here upsets the resume sequence of the libertas driver. Adding the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume behaviour. The rfkill state is maintained by the hardware over suspend/resume so no extra consideration is needed here. Signed-off-by:

As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

Pull Sparc updates from David S. Miller: 1) Remove the idiotic situation wherein Leon was a special case in all of the TLB/cache handling code. The worst side effect of this bogosity is that you couldn't build a kernel with Leon support enabled (to get better build coverage), and test boot it on a non-LEON cpu. Leon is, in all core respects, programatically identical to the 32-bit SRMMU. Except that they put the TLB registers in a different alternate address space location. Through code patching (for fast paths) and run time checks, this issue is now a thing of the past. From Sam Ravnborg. 2) There was a mis-merge of arch/sparc/Kconfig for one of the clockevents changes that went in, causing 32-bit sparc to start failing to build. I merged in your tree to get those clockevents changes (and added a note to the merge commit) then added Stephen Rothwell's fix for the merge error. 3) Software quad floating point emulation was not working properly on more recent Niagara chips, because the way the situation is reported by the cpu has changed. Nobody noticed because gcc emits calls to software emulation routines in glibc. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: (25 commits) sparc: fix sparc64 build due to leon.h inclusion sparc32: remove unused variable in head_32.S sparc32,leon: fix leon bootup sparc32: Export leon_dma_ops to modules. sparc32: support leon + sun in dma_make_coherent() sparc32,leon: always support leon in ioport sparc32,leon: always include leon_pmc in build sparc32: refactor cpu_idle() sparc32: srmmu_probe now knows about leon too sparc32: drop LEON hack for ASI_M_MMUREGS sparc32: introduce run-time patching of srmmu access functions sparc32: introduce support for run-time patching for all shared assembler code sparc32,leon: fix section mismatch warning sparc32,leon: always include leon_smp + leon_mm in build sparc32,leon: always include leon_kernel in build sparc32,leon: clean up leon.h sparc32: handle leon in cpu.c sparc32: handle leon in irq_32.c sparc32: add support for run-time patching of leon/sun single instructions sparc32: introduce sparc32_start_kernel called from head_32.S ...

The GPIO devicetree binding in 3.5 doesn't register the various LPC32xx GPIO banks via DT subnodes but always all at once, and changes the gpio referencing to 3 cells (bank, gpio, flags). This patch adjusts the DTS files to this binding that was just accepted to the gpio subsystem. Signed-off-by:
