.SH NAME

kpatch-build \- build script

.SH SYNOPSIS

kpatch-build [options] <patch file>

.SH DESCRIPTION

This script takes a patch based on the version of the kernel 

currently running and creates a kernel module that will replace 

modified functions in the kernel such that the patched code takes 

effect.

This script currently only works on Fedora and will need to be adapted 

to work on other distros.  

.SH OPTIONS

-h|--help

-a|--archversion

   Specify the kernel arch version

-r|--sourcerpm

   Specify kernel source RPM

-s|--sourcedir

   Specify kernel source directory

-c|--config

   Specify kernel config file

-v|--vmlinux

   Specify original vmlinux

-j|--jobs

   Specify the number of make jobs

-t|--target

   Specify custom kernel build targets

-n|--name

   Specify the name of the kpatch module

-o|--output

   Specify output folder

-d|--debug

   (can be specified multiple times)

--skip-cleanup

   Skip post-build cleanup

--skip-gcc-check

   Skips check that ensures that the system gcc version and

   the gcc version that built the kernel match.  Skipping this

   check is not recommended, but is useful if the exact gcc

   version is not available or is not easily installed. Use

   only when confident that the two versions of gcc output

   identical objects for a given target.  Otherwise, use of

   this option might result in unexpected changed objects

   being detected.
