Log:
Make ADAPTIVE_GIANT as the default in the kernel and remove the option.
Currently, Giant is not too much contented so that it is ok to treact it
like any other mutexes.
Please don't forget to update your own custom config kernel files.
Approved by: cognet, marcel (maintainers of arches where option is
not enabled at the moment)
Also even when it is contended, the ADAPTIVE_GIANT behaviour has always
been a big win in my testing.
