tools include uapi: Grab a copy of linux/mount.h

2019-01-08T17:09:28+00:00

We were using a copy of uapi/linux/fs.h to create the mount syscall 'flags' string table to use in 'perf trace', to convert from the number obtained via the raw_syscalls:sys_enter into a string, using tools/perf/trace/beauty/mount_flags.sh, but in e262e32d6bde ("vfs: Suppress MS_* flag defs within the kernel unless explicitly enabled") those defines got moved to linux/mount.h, so grab a copy of mount.h too. Keep the uapi/linux/fs.h as we'll use it for the SEEK_ constants.

tools uapi: fix RISC-V 64-bit support

2019-01-07T15:59:28+00:00

The BPF library is not built on 64-bit RISC-V, as the BPF feature is not detected. Looking more in details, feature/test-bpf.c fails to build with the following error: | In file included from /tmp/linux-4.19.12/tools/include/uapi/asm/bitsperlong.h:17, | from /tmp/linux-4.19.12/tools/include/uapi/asm-generic/unistd.h:2, | from /usr/include/riscv64-linux-gnu/asm/unistd.h:1, | from test-bpf.c:2: | /tmp/linux-4.19.12/tools/include/asm-generic/bitsperlong.h:14:2: error: #error Inconsistent word size. Check asm/bitsperlong.h | #error Inconsistent word size. Check asm/bitsperlong.h | ^~~~~ The UAPI from the tools directory is missing RISC-V support, therefore bitsperlong.h from asm-generic is used, defaulting to 32 bits. Fix that by adding tools/arch/riscv/include/uapi/asm/bitsperlong.h as a copy of arch/riscv/include/uapi/asm/bitsperlong.h and by updating tools/include/uapi/asm/bitsperlong.h.
