From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mark Corbin Date: Wed, 2 Jan 2019 15:15:58 +0000 Subject: [Buildroot] [PATCH v2 1/1] package/glibc: fix include of syscalls.h for RISC-V architecture Message-ID: <20190102151559.32221-1-mark.corbin@embecosm.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net UAPI header file asm/syscalls.h has been merged into the UAPI asm/unistd.h header file for the RISC-V architecture in the 4.20 kernel. This causes the glibc 2.28 build to break. This commit applies the upstream glibc patch for this issue.
