This is a note to let you know that I've just added the patch titled s390/vdso: remove -nostdlib compiler flag to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: s390-vdso-remove-nostdlib-compiler-flag.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e7cfd1284f8cf64167685dfa4e13f3b1f13c467f Author: Masahiro Yamada <masahiroy@xxxxxxxxxx> Date: Mon Nov 8 01:21:11 2021 +0900 s390/vdso: remove -nostdlib compiler flag [ Upstream commit 7b737adc10d269e7fdf714ae2caa2281b6a801cf ] The -nostdlib option requests the compiler to not use the standard system startup files or libraries when linking. It is effective only when $(CC) is used as a linker driver. Since commit 2b2a25845d53 ("s390/vdso: Use $(LD) instead of $(CC) to link vDSO"), $(LD) is directly used, hence -nostdlib is unneeded.
