Similar to 'cc-option' or 'ld-option', it is occasionally necessary to check whether the assembler supports certain ISA extensions. In the arm64 code we currently do this in Makefile with an additional define: lseinstr := $(call as-instr,.arch_extension lse,-DCONFIG_AS_LSE=1) Add the 'as-instr' option so that it can be used in Kconfig directly: def_bool $(as-instr,.arch_extension lse) Acked-by: Masahiro Yamada <masahiroy@kernel.org> Reviewed-by: Vladimir Murzin <vladimir.murzin@arm.com> Tested-by: Vladimir Murzin <vladimir.murzin@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Will Deacon <will@kernel.org> |

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.
