2009-06-13FRV: Fix interaction with new generic header stuffDavid Howells
Fix interaction with new generic header stuff as added by: commit 6103ec56c65c33774c7c38652c8204120c3c7519 Author: Arnd Bergmann <arnd@arndb.de> Date: Wed May 13 22:56:27 2009 +0000 asm-generic: add generic ABI headers The problem is that asm/signal.h has been made to include asm-generic/signal.h, but the redundant stuff from asm/signal.h has not been discarded, leading to multiple redefinitions.

2009-06-13avr32: Fix oops on unaligned user accessHaavard Skinnemoen
The unaligned address exception handler (and others) does not scan the fixup tables before oopsing. This is bad because it means passing a badly aligned pointer from user space might crash the kernel. Fix this by scanning the fixup tables in _exception(). This should resolve the issue for unaligned addresses as well as other less common exceptions that might be happening during a userspace access. The page fault handler already does fixup processing.

2009-06-13i2c-ocores: Can add I2C devices to the busRichard Röjfors
There is sometimes a need for the ocores driver to add devices to the bus when installed. i2c_register_board_info can not always be used, because the I2C devices are not known at an early state, they could for instance be connected on a I2C bus on a PCI device which has the Open Cores IP. i2c_new_device can not be used in all cases either since the resulting bus nummer might be unknown. The solution is the pass a list of I2C devices in the platform data to the Open Cores driver. This is useful for MFD drivers.

2009-06-13i2c: OMAP2/3: Fix scll/sclh calculationsAaro Koskinen
Fix scll/sclh calculations for HS and fast modes. Currently the driver uses equal (roughly) low/high times which will result in too short low time. OMAP3430 TRM gives the following equations: F/S: tLow = (scll + 7) * internal_clk tHigh = (sclh + 5) * internal_clk HS: tLow = (scll + 7) * fclk tHigh = (sclh + 5) * fclk Furthermore, the I2C specification sets the following minimum values for HS tLow/tHigh for capacitive bus loads 100 pF (maximum speed 3400) and 400 pF (maximum speed 1700): speed tLow tHigh 3400 160 ns 60 ns 1700 320 ns 120 ns and for F/S: speed tLow tHigh 400 1300 ns 600 ns 100 4700 ns 4000 ns By using duty cycles 33/66 (HS, F) and 50/50 (S) we stay above these minimum values.

2009-06-13i2c: Blackfin TWI: fix transfer errors with repeat startFrank Shew
We have a custom BF537 board with an I2C RTC (MAX DS3231) running uclinux 2007R1 for some time. Recently during migration to 2008R1.5-RC3 we losted access to the RTC. The RTC driver calls 'i2c_transfer()' which in turns calls 'bfin_twi_master_xfer()' in i2c-bfin-twi.c. Compared with 2007R1, it looks like the 2008R1.5 version of i2c-bin-twi.c has a new mode 'TWI_I2C-MODE_REPEAT' which corresponds to the Repeat Start Condition described in the HRM. However, according to the HRM, at XMIT or RECV interrupt and when the data count is 0, not only is the RESTART bit supposed to be set, but MDIR must also be set if the next operation is a receive sequence, and cleared if not. Currently there is no code that looks at the I2C_M_RD bit in the flag from the next cur_msg and set/clear the MDIR flag accordingly at the same time that the RSTART bit is set. Instead, MDIR is set or cleared (by OR'ing with 0?) after the RESTART bit has been cleared during handling of MCOMP interrupt. It appears that this is causing our failure with reading the RTC, as a quick patch to set/clear MDIR when RESTART is set seem to solve our problem.

2009-06-12Driver Core: Rework platform suspend/resume, print warningMagnus Damm
This patch reworks the platform driver code for legacy suspend and resume to avoid installing callbacks in struct device_driver. A warning is also added telling users to update the platform driver to use dev_pm_ops. The functions platform_legacy_suspend()/resume() directly call suspend and resume callbacks in struct platform_driver instead of wrapping things in platform_drv_suspend()/resume().

2009-06-12PM: Remove device_type suspend()/resume()Magnus Damm
This patch removes the legacy callbacks ->suspend() and ->resume() from struct device_type. These callbacks seem unused, and new code should instead make use of struct dev_pm_ops.

2009-06-12PM/Hibernate: Move memory shrinking to snapshot.c (rev. 2)Rafael J. Wysocki
A future patch is going to modify the memory shrinking code so that it will make memory allocations to free memory instead of using an artificial memory shrinking mechanism for that. For this purpose it is convenient to move swsusp_shrink_memory() from kernel/power/swsusp.c to kernel/power/snapshot.c, because the new memory-shrinking code is going to use things that are local to kernel/power/snapshot.c .

Remove the shrinking of memory from the suspend-to-RAM code, where it is not really necessary. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Acked-by: Nigel Cunningham <nigel@tuxonice.net> Acked-by: Wu Fengguang <fengguang.wu@intel.com>
2009-06-12PM: Remove bus_type suspend_late()/resume_early() V2Magnus Damm
Remove the ->suspend_late() and ->resume_early() callbacks from struct bus_type V2. These callbacks are legacy stuff at this point and since there seem to be no in-tree users we may as well remove them. New users should use dev_pm_ops.

2009-06-12PM core: rename suspend and resume functionsAlan Stern
This patch (as1241) renames a bunch of functions in the PM core. Rather than go through a boring list of name changes, suffice it to say that in the end we have a bunch of pairs of functions: device_resume_noirq dpm_resume_noirq device_resume dpm_resume device_complete dpm_complete device_suspend_noirq dpm_suspend_noirq device_suspend dpm_suspend device_prepare dpm_prepare in which device_X does the X operation on a single device and dpm_X invokes device_X for all devices in the dpm_list. In addition, the old dpm_power_up and device_resume_noirq have been combined into a single function (dpm_resume_noirq). Lastly, dpm_suspend_start and dpm_resume_end are the renamed versions of the former top-level device_suspend and device_resume routines.

2009-06-12PM: Rename device_power_down/up()Magnus Damm
Rename the functions performing "_noirq" dev_pm_ops operations from device_power_down() and device_power_up() to device_suspend_noirq() and device_resume_noirq(). The new function names are chosen to show that the functions are responsible for calling the _noirq() versions to finalize the suspend/resume operation. The current function names do not perform power down/up anymore so the names may be misleading. Global function renames: - device_power_down() -> device_suspend_noirq() - device_power_up() -> device_resume_noirq() Static function renames: - suspend_device_noirq() -> __device_suspend_noirq() - resume_device_noirq() -> __device_resume_noirq() Signed-off-by: Magnus Damm <damm@igel.co.jp> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Acked-by: Len Brown <lenb@kernel.org> Signed-off-by: Rafael J.

This is the last unification step. Here we do remove one of the files and rename the left one as cpu.c, as both are now the same.

2009-06-12x86: unify power/cpu_(32|64) copyright notesSergio Luis
In this step, we do unify the copyright notes for both files cpu_32.c and cpu_64.c, making such files exactly the same. It's the last step before the actual unification, that will rename one of them to cpu.c and remove the other one.

In this step we do unify cpu_32.c and cpu_64.c functions that work on restoring the saved processor state. Also, we do eliminate the forward declaration of fix_processor_context() for X86_64, as it's not needed anymore.
