Subject: [PATCH] perf arm64: Fix mksyscalltbl when system kernel headers are ahead of the kernel
Date: Tue, 21 May 2019 06:02:03 +0300 [thread overview]
Message-ID: <20190521030203.1447-1-vt@altlinux.org> (raw)
When a host system has kernel headers that are newer than a compiling
kernel, mksyscalltbl fails with errors such as:
<stdin>: In function 'main':
<stdin>:271:44: error: '__NR_kexec_file_load' undeclared (first use in this function)
<stdin>:271:44: note: each undeclared identifier is reported only once for each function it appears in
<stdin>:272:46: error: '__NR_pidfd_send_signal' undeclared (first use in this function)
<stdin>:273:43: error: '__NR_io_uring_setup' undeclared (first use in this function)
<stdin>:274:43: error: '__NR_io_uring_enter' undeclared (first use in this function)
<stdin>:275:46: error: '__NR_io_uring_register' undeclared (first use in this function)
tools/perf/arch/arm64/entry/syscalls//mksyscalltbl: line 48: /tmp/create-table-xvUQdD: Permission denied
mksyscalltbl is compiled with default host includes, but run with
compiling kernel tree includes, causing some syscall numbers being
undeclared.
