This is the s390 version of commit40576e5e63("x86: alternative.h: use asm_inline for all alternative variants"). See commiteb11186930("compiler-types.h: add asm_inline definition") for more details. With this change the compiler will not generate many out-of-line versions for the three instruction sized arch_spin_unlock() function anymore. Due to this gcc seems to change a lot of other inline decisions which results in a net 6k text size growth according to bloat-o-meter (gcc 9.2 with defconfig). But that's still better than having many out-of-line versions of arch_spin_unlock(). Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
