Subject: [PATCH] kpatch-build: add cross-compilation support
|
||||
|
||||
This patch introduces new option for kpatch-build
|
||||
script "--cross-compile" which can be used for
|
||||
specifying cross-complier prefix.
|
||||
It allows to build live patches not only on
|
||||
target system, but also on hosts for a target other
|
||||
than the one on which the compiler is running
|
||||
|
||||
Also removed quotes in exec lines, so it is
|
||||
possible to pass multy-component strings like
|
||||
"ccache x86_64-xelinux-linux-" as cross-compiler

Subject: [PATCH] kpatch-build: allow overriding of distro name
|
||||
|
||||
It is sometimes useful to have ability to override
|
||||
distro name, for example during cross-compilation
|
||||
build when livepatch modules will be ran on the
|
||||
target which differs from host.
|
||||
|
||||
This patch adds a new --distro option which
|
||||
implements all needed functionality
