From: Wei Liu <redacted> Add an config file snippet which enalbes additional options useful for running the kernel in a Hyper-V guest. The expected use case is a user provides an existing config file then executes `make hvconfig`. It will merge those options with the provided config file. Based on similar concept for Xen and KVM. Signed-off-by: Wei Liu <redacted> --- RFC: I only tested this on x86. Although the config options included in hv_guest.config don't seem to be arch-specific, we should probably move the ones not yet implemented on Arm to an x86 specific config file. --- Documentation/admin-guide/README.rst | 3 +++ kernel/configs/hv_guest.config | 33 ++++++++++++++++++++++++++++ scripts/kconfig/Makefile | 5 +++++ 3 files changed, 41 insertions(+) create mode 100644 kernel/configs/hv_guest.config
