Mauro Carvalho Chehab 54a19b4d3f docs: ABI: cleanup several ABI documents
There are some ABI documents that, while they don't generate
any warnings, they have issues when parsed by get_abi.pl script
on its output result.

Address them, in order to provide a clean output.

Hyeonjun Lim 817eecbf82 doc: Update the name of profiling based on sysfs
The ./kernel/ksysfs.c defines 'profiling' w/o 'profile' like
"KERNEL_ATTR_RW(profiling)".  We need to synchronize the content between ksys.c
source and kernel doc.

Dave Hansen 22b8ce9470 profiling: dynamically enable readprofile at runtime
Way too often, I have a machine that exhibits some kind of crappy
behavior.  The CPU looks wedged in the kernel or it is spending way too
much system time and I wonder what is responsible.

I try to run readprofile.  But, of course, Ubuntu doesn't enable it by
default.  Dang!

The reason we boot-time enable it is that it takes a big bufffer that we
generally can only bootmem alloc.  But, does it hurt to at least try and
runtime-alloc it?

To use:
echo 2 > /sys/kernel/profile

Then run readprofile like normal.

This should fix the compile issue with allmodconfig.  I've compile-tested
on a bunch more configs now including a few more architectures.
