tools uapi: fix RISC-V 64-bit support
[ Upstream commit d0df00e30e4bf9bc27ddbd092ad683ff6121b360 ]
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.
