Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux
![]() Perf shows we're spending a lot of time in find_insn() and the statistics show we have around 3.2 million instruction. Increase the hash table size to reduce the bucket load from around 50 to 3. This shaves about 2s off of objtool on vmlinux.o runtime, down to 16s.

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.
