The commit 911dec0db4de6ccc544178a8ddaf9cec0a11d533 "xen/arm: Fix compile errors when drivers are compiled as modules." exports the neccessary functions. But to guard ourselves against out-of-tree modules and future drivers hitting this, lets export all of the relevant hypercalls.

2012-10-29ARM: 7567/1: io: avoid GCC's offsettable addressing modes for halfword accessesWill Deacon
Using the 'o' memory constraint in inline assembly can result in GCC generating invalid immediate offsets for memory access instructions with reduced addressing capabilities (i.e. smaller than 12-bit immediate offsets): http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54983 As there is no constraint to specify the exact addressing mode we need, fallback to using 'Q' exclusively for halfword I/O accesses. This may emit an additional add instruction (using an extra register) in order to construct the address but it will always be accepted by GAS.

When CONFIG_VFPv3 is set, but the kernel is booted on a pre-VFPv3 core, the code attempts to save and restore the d16-d31 VFP registers. These are only present on non-D16 VFPv3+, so this results in an undefined instruction exception. The code didn't crash before commit 846a136 because the save and restore code was only touching d0-d15, present on all VFP. Fix by implementing a request from Russell King to add a new HWCAP flag that affirmatively indicates the presence of the d16-d31 registers: http://marc.info/?l=linux-arm-kernel&m=135013547905283&w=2 and some feedback from Måns to clarify the name of the HWCAP flag.

2012-10-29ARM: 7565/1: sched: stop sched_clock() during suspendFelipe Balbi 2
The scheduler imposes a requirement to sched_clock() which is to stop the clock during suspend, if we don't do that any RT thread will be rescheduled in the future which might cause any sort of problems. This became an issue on OMAP when we converted omap-i2c.c to use threaded IRQs, it turned out that depending on how much time we spent on suspend, the I2C IRQ thread would end up being rescheduled so far in the future that I2C transfers would timeout and, because omap_hsmmc depends on an I2C-connected device to detect if an MMC card is inserted in the slot, our rootfs would just vanish. arch/arm/kernel/sched_clock.c already had an optional implementation (sched_clock_needs_suspend()) which would handle scheduler's requirement properly, what this patch does is simply to make that implementation non-optional. Note that this has the side-effect that printk timings won't reflect the actual time spent on suspend so other methods to measure that will have to be used. This has been tested with beagleboard XM (OMAP3630) and pandaboard rev A3 (OMAP4430). Suspend to RAM is now working after this patch. Thanks to Kevin Hilman for helping out with debugging.

The i2c core driver will turn the platform device ID to busnum When using platfrom device ID as -1, it means dynamically assigned the busnum. When writing code, we need to make sure the busnum, and call i2c_register_board_info(int busnum, ...) to register device if using -1, we do not know the value of busnum In order to solve this issue, set the platform device ID as a fix number Here using 0 to match the busnum used in i2c_regsiter_board_info() Signed-off-by: Bo Shen <voice.shen@atmel.com> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: Ludovic Desroches <ludovic.desroches@atmel.com> Cc: stable <stable@vger.kernel.org> [very long time]

2012-10-24ARM: AM33XX: Fix configuration of dmtimer parent clock by dmtimer ↵Vaibhav Hiremath
driverDate:Wed, 17 Oct 2012 13:55:55 -0500 Add dmtimer clock aliases for AM33XX devices so that the parent clock for the dmtimer can be set correctly by the dmtimer driver. Without these clock aliases the dmtimer driver will fail to find the parent clocks for the dmtimer. Verified that DMTIMERs can be successfully requested on AM335x beagle bone.

2012-10-23ARM: imx: select HAVE_IMX_SRC when SMP is enabledShawn Guo
With being part of multi-platform support, SMP can be enabled by other platform even when SOC_IMX6Q is deselected. It leads to a situation that arch/arm/mach-imx/platsmp.c is built without HAVE_IMX_SRC selection which will cause build error. For example, the following link errors will be seen when building imx5 with other v7 platforms. arch/arm/mach-imx/built-in.o: In function `imx_cpu_die': platform-ahci-imx.c:(.text+0x219c): undefined reference to `imx_enable_cpu' arch/arm/mach-imx/built-in.o: In function `imx_boot_secondary': platform-ahci-imx.c:(.cpuinit.text+0x14): undefined reference to `imx_set_cpu_jump' platform-ahci-imx.c:(.cpuinit.text+0x20): undefined reference to `imx_enable_cpu' Select HAVE_IMX_SRC as long as SMP is enabled to fix the problem.

2012-10-22ARM: OMAP3: Beagle: fix OPP customization and initcall orderingKevin Hilman
After commit 24d7b40a60cf19008334bcbcbd98da374d4d9c64 (ARM: OMAP2+: PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered using an existing CPU device, not the omap_device for MPU-SS. First, fix the board file to use get_cpu_device() as required by the above commit, otherwise custom OPPs will be added to the wrong device. Second, the board files OPP init is called from the its init_machine method, and the generic CPU devices are not yet created when init_machine is run. Therefore OPP initialization will fail. To fix, use a device_initcall() for the board file's OPP customization, and make the device_initcall board-specific by using a machine_is check.

In any case, hotplugis selected by other non-experimental options which then cause a Kconfig warning. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
