tools/include/uapi: Fix for parisc and xtensa

2022-09-13T12:04:35Z

tools/include/uapi/asm/errno.h currently attempts to include non-existent arch-specific errno.h header for xtensa. Remove this case so that is used instead, and add the missing arch-specific header for parisc.

ia64: tools: remove inclusion of ia64-specific version of errno.h header

2021-04-16T23:10:37Z

There is no longer an ia64-specific version of the errno.h header below arch/ia64/include/uapi/asm/, so trying to build tools/bpf fails with: CC /usr/src/linux/tools/bpf/bpftool/btf_dumper.o In file included from /usr/src/linux/tools/include/linux/err.h:8, from btf_dumper.c:11: /usr/src/linux/tools/include/uapi/asm/errno.h:13:10: fatal error: ../../../arch/ia64/include/uapi/asm/errno.h: No such file or directory 13 | #include "../../../arch/ia64/include/uapi/asm/errno.h" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. Thus, just remove the inclusion of the ia64-specific errno.h so that the build will use the generic errno.h header on this target which was used there anyway as the ia64-specific errno.h was just a wrapper for the generic header.

tools uapi: fix RISC-V 64-bit support

2019-01-07T15:59:28Z

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.
