From: William Cohen Date: Fri, 1 Mar 2019 20:00:41 +0000 (-0500) Subject: arm64/stacktrace: Export save_stack_trace_regs() X-Git-Tag: v5.1-rc2~24^2~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c82fd1e6bd55ecc001e610e5484e292a7d8a39fc;p=thirdparty%2Flinux.git arm64/stacktrace: Export save_stack_trace_regs() The ARM64 implements the save_stack_trace_regs function, but it is unusable for any diagnostic tooling compiled as a kernel module due the missing EXPORT_SYMBOL_GPL for the function. Export save_stack_trace_regs() to align with other architectures such as s390, openrisc, and powerpc. This is similar to the ARM64 export of save_stack_trace_tsk() added in git commit e27c7fa015d6.
