From: Yann Droneaud Date: Thu, 27 Mar 2014 11:10:33 +0000 (+0100) Subject: IB: Allow build of hw/ and ulp/ subdirectories independently X-Git-Tag: omap-for-v3.16/fixes-against-rc1~68^2^6~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=729ee4efcc29c040a1729c058f03fae3cebc6035;p=pandora-kernel.git IB: Allow build of hw/ and ulp/ subdirectories independently It is not possible to build only the drivers/infiniband/hw/ (or ulp/) subdirectory with command such as: $ make ARCH=x86_64 O=./obj-x86_64/ drivers/infiniband/hw/ This fails with following error messages: make[2]: Nothing to be done for `all'. make[2]: Nothing to be done for `relocs'. CHK include/config/kernel.release Using /home/ydroneaud/src/linux as source for kernel GEN /home/ydroneaud/src/linux/obj-x86_64/Makefile CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CALL /home/ydroneaud/src/linux/scripts/checksyscalls.sh /home/ydroneaud/src/linux/scripts/Makefile.build:44: /home/ydroneaud/src/linux/drivers/infiniband/hw/Makefile: No such file or directory make[2]: *** No rule to make target `/home/ydroneaud/src/linux/drivers/infiniband/hw/Makefile'. Stop. make[1]: *** [drivers/infiniband/hw/] Error 2 make: *** [sub-make] Error 2 This patch creates a Makefile in hw/ and ulp/ and moves each corresponding parts of drivers/infiniband/Makefile in the new Makefiles. It should not break build except if some hw/ drivers or ulp/ were allowed previously to be built while CONFIG_INFINIBAND is set to 'n', but according to drivers/infiniband/Kconfig, it's not possible. So it should be safe to apply. Signed-off-by: Yann Droneaud Reviewed-by: Bart Van Assche Signed-off-by: Roland Dreier --- Reading git-diff-tree failed
