This patch changes pin multiplexing init to allow registering custom function. The omap_cfg_reg() func will be split into omap processor specific functions in later patch. This is done to make adding omap3 pin multiplexing easier. Signed-off-by: NTony Lindgren <tony@atomide.com>

Currently, the GPIO interrupt handling is duplicating some of the work done by the generic IRQ handlers (handle_edge_irq, handle_level_irq) such as detecting nesting, handling re-triggers etc. Remove this duplication and use generic hooks based on IRQ type. Using generic IRQ handlers ensures correct behavior when using threaded interrupts introduced by the -rt patch.

The clearing was moved to the unmask hook because it is known to run after the interrupt handler has actually run. Before this patch, if interrupts are threaded, the clearing/unmasking of level triggered interrupts would be done before the threaded handler actually ran.

Start cleaning up GPIO handling for OMAP5912 OSK board: - Initialize GPIOs using the cross-platform calls, not the old OMAP-private ones. - Move touchscreen setup out of ads7846 code into board-specfic setup code, where it belongs.

The reason is that some architectures add the "-traditional" flag to the invocation of $(AS), which disables variadic macro argument support.

Increase the PNP "number of devices" limit. We currently use an unsigned char, which limits us to 256 devices per protocol. This patch changes that to an unsigned int. Not all backends can take advantage of this: we limit ISAPNP to 10 devices in isapnp_cfg_begin(), and PNPBIOS is limited to 256 devices because the BIOS interfaces use a one-byte device node number. But there is no limit on the number of PNPACPI devices we may have. Large HP Integrity machines have more than 256, which causes the current "unsigned char number" to wrap around. This causes errors like this: pnp: PnP ACPI init kobject_add failed for 00:00 with -EEXIST, don't try to register things with the same name in the same directory.

It's really a pretty ugly thing to need, and some day it will hopefully be obviated by teaching gcc about the magic calling conventions for the low-level system call code, but in the meantime we can at least add big honking comments about why we need these insane and strange macros. I took my comments from my version of the macro, but I ended up deciding to just pick Roland's version of the actual code instead (with his prettier syntax that uses vararg macros). Thus the previous two commits that actually implement it. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Use asmlinkage_protect in sys_io_getevents, because GCC for i386 with CONFIG_FRAME_POINTER=n can decide to clobber an argument word on the stack, i.e. the user struct pt_regs. Here the problem is not a tail call, but just the compiler's use of the stack when it inlines and optimizes the body of the called function. This seems to avoid it.

由 Roland McGrath 提交于
The prevent_tail_call() macro works around the problem of the compiler clobbering argument words on the stack, which for asmlinkage functions is the caller's (user's) struct pt_regs. The tail/sibling-call optimization is not the only way that the compiler can decide to use stack argument words as scratch space, which we have to prevent. Other optimizations can do it too. Until we have new compiler support to make "asmlinkage" binding on the compiler's own use of the stack argument frame, we have work around all the manifestations of this issue that crop up. More cases seem to be prevented by also keeping the incoming argument variables live at the end of the function. This makes their original stack slots attractive places to leave those variables, so the compiler tends not clobber them for something else. It's still no guarantee, but it handles some observed cases that prevent_tail_call() did not.

This patch also resolves hangs on boot: http://lkml.org/lkml/2008/2/23/263 http://bugzilla.kernel.org/show_bug.cgi?id=10093 The bug was causing once-in-few-reboots 10-15 sec wait during boot on certain laptops. Earlier commit 40d6a146 added smp_call_function in cpu_idle_wait() to kick cpus that are in tickless idle. Looking at cpu_idle_wait code at that time, code seemed to be over-engineered for a case which is rarely used (while changing idle handler). Below is a simplified version of cpu_idle_wait, which just makes a dummy smp_call_function to all cpus, to make them come out of old idle handler and start using the new idle handler. It eliminates code in the idle loop to handle cpu_idle_wait. Signed-off-by: NVenkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
