Commit Message

Mark Corbin Jan. 2, 2019, 2:17 p.m. UTC
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.

Fixes:

+    riscv: add asm/unistd.h UAPI header
+
+    Marcin Juszkiewicz reported issues while generating syscall table for riscv
+    using 4.20-rc1. The patch refactors our unistd.h files to match some other
+    architectures.
+
+    - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
+    - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
+    - Adjust kernel asm/unistd.h
+
+    So now asm/unistd.h UAPI header should show all syscalls for riscv.
+
+<asm/syscalls.h> may be restored by
+
+Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header
+Date: Tue, 11 Dec 2018 09:09:35 +0100
+
+UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header,
+which did resolve issue with missing syscalls macros resulting in
+glibc (2.28) build failure. It also broke glibc in a different way:
+asm/syscalls.h is being used by glibc. I noticed this while doing
+Fedora 30/Rawhide mass rebuild.
+
+The patch returns asm/syscalls.h header and incl. it into asm/unistd.h.
+I plan to send a patch to glibc to use asm/unistd.h instead of
+asm/syscalls.h
+
+In the meantime, we use __has_include__, which was added to GCC 5, to
+check if <asm/syscalls.h> exists before including it.  Tested with
+build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7.
+
+	[BZ #24022]
+	* sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if
+	<asm/syscalls.h> exists with __has_include__ before including it.
