[Qemu-devel] [PATCH 1/1] update-linux-headers: change SRCARCH to ARCH

[Sam Bobroff]

Currently, update-linux-headers.sh will crash when run with a clean
checkout of a recent version of the linux kernel source (e.g. 4.10-rc1):

scripts/Makefile.headersinst:62: *** Missing generated UAPI file
./arch/arm/include/generated/uapi/asm/unistd-common.h.  Stop.

This seems to be due to the script setting "SRCARCH" rather than
"ARCH" when invoking the kernel's "headers_install" target, which
prevents dependencies from being applied correctly.  (The kernel's
Documentation/kbuild/headers_install.txt refers only to "ARCH".)

So, change SRCARCH to ARCH, which corrects the problem.
