arch, ftrace: for KASAN put hard/soft IRQ entries into separate sections

2016-03-25T23:37:42+00:00

KASAN needs to know whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. Move the definition of __irq_entry to so that the users don't need to pull in . Also introduce the __softirq_entry macro which is similar to __irq_entry, but puts the corresponding functions to the .softirqentry.text section.

whack-a-mole: no need to set_fs(USER_DS) in {start,flush}_thread()

2015-04-12T02:24:31+00:00

flush_old_exec() has already done that. Back on 2011 a bunch of instances like that had been kicked out, but that hadn't taken care of then-out-of-tree architectures, obviously, and they served as reinfection vector... Signed-off-by: Al Viro

C6x: time: Ensure consistency in __init

2015-03-26T14:31:47+00:00

time_init invokes timer64_init (which is __init annotation) since all of these are invoked at init time, lets maintain consistency by ensuring time_init is marked appropriately as well. This fixes the following warning with CONFIG_DEBUG_SECTION_MISMATCH=y WARNING: vmlinux.o(.text+0x3bfc): Section mismatch in reference from the function time_init() to the function .init.text:timer64_init() The function time_init() references the function __init timer64_init(). This is often because time_init lacks a __init annotation or the annotation of timer64_init is wrong.
