... and get rid of idiotic struct pt_regs * in asm-generic/syscalls.h prototypes of the same, while we are at it. Eventually we want those in linux/syscalls.h, of course, but that'll have to wait a bit. Note that there are *three* variants of sys_clone() order of arguments. Braindamage galore...

2012-11-28alpha: simplify fork and friendsAl Viro
* no need to restore everything from switch_stack when we only need $26 * no need to pass current_pt_regs() manually, we can just as easily calculate it in alpha_clone/alpha_vfork ($8 + constant) * interpretation of zero usp as "use the parent's" is simpler in copy_thread(); let fork and vfork just pass 0.

2012-11-28sh64: fix altstack switching on sigreturnAl Viro
incidentally, declaring a local variable as __user (!) to make sparse STFU is really sick. Especially since sparse had been 100% right - it *is* a bug. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-11-29video: exynos_dp: Fix incorrect setting for INT_CTLAjay Kumar
INT_CTL register contains bits INT_POL0 and INT_POL1, and not INT_POL. This patch fixes the wrong register setting for INT_CTL. Signed-off-by: Ajay Kumar <ajaykumar.rs@samsung.com> Signed-off-by: Jingoo Han <jg1.han@samsung.com>
2012-11-29video: exynos_dp: Reset and initialize DP before requesting irqAjay Kumar
If DP is not reset properly before kernel bootup(in bootloader code), there can be few pending interrupts, and sometimes they invoke DP irq handler as soon as the irq handler is registered in DP probe. So, we make the DP driver more robust by resetting and initializing DP at the earliest and then registering the irq handler.

2012-11-29video: exynos_dp: Enable hotplug interruptsSean Paul
Enable hotplug interrupts and move the hotplug scheduling into the interrupt handler. This allows us to introduce a screen at any time while we're running.

2012-11-29video: exynos_dp: Move hotplug into a workqueueSean Paul
Move the hotplug related code from probe and resume into a workqueue. This allows us to initialize the DP driver (and resume it) when there is no monitor connected.

2012-11-29video: exynos_dp: Improve EDID error handlingSean Paul
EDID error handling has 2 problems: - It doesn't fail as early as it can - The retry counts for i2c and aux transactions are huge This patch fails if the initial i2c transaction fails, and reduces the aux and i2c retry counts down to 3.
