I almost forgot about it again, but noticed it was missing from your tree. - Soumya PN sent me a clean up patch to not disable interrupts when taking the tasklist_lock for read, as it's unnecessary because that lock is never taken for write in irq context. - Newer gcc's can cause the jump in the function_graph code to the global ftrace_stub label to be a short jump instead of a long one. As that jump is dynamically converted to jump to the trace code to do function graph tracing, and that conversion expects a long jump it can corrupt the ftrace_stub itself (it's directly after that call).

2016-05-22x86: remove more uaccess_32.h complexityLinus Torvalds4-31/+3
I'm looking at trying to possibly merge the 32-bit and 64-bit versions of the x86 uaccess.h implementation, but first this needs to be cleaned up. For example, the 32-bit version of "__copy_from_user_inatomic()" is mostly the special cases for the constant size, and it's actually almost never relevant. Most users aren't actually using a constant size anyway, and the few cases that do small constant copies are better off just using __get_user() instead. So get rid of the unnecessary complexity.

2016-05-21x86 isa: add back X86_32 dependency on CONFIG_ISALinus Torvalds1-2/+2
Commit b3c1be1b789c ("base: isa: Remove X86_32 dependency") made ISA support available on x86-64 too. That's not right - while there are some LPC-style devices that might be useful still and be based on ISA-like IP blocks, that is *not* an excuse to try to enable any random legacy drivers. Such drivers should be individually enabled and made to perhaps depend on ISA_DMA_API instead (which we have continued to support on x86-64). Or we could add another "ISA_XYZ_API" that we support that doesn't enable random old drivers that aren't even 64-bit clean nor do we have any test coverage for. Turning off ISA will now also turn off some drivers that have been marked as depending on it as part of this series, and that used to work on modern platforms. See for example commits ad7afc38eab3..cc736607c86d, which may also need to be reverted. This commit means that the warnings that came in due to enabling ISA widely are now gone again.

To prepare the alarm IRQ support, the current code enables all the alarm types by setting each AE_x to 1.
