X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee4ee527278a66321301d4f1f5ae22e49ab18fad;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git sparc64: Fix bug in PTRACE_SETFPREGS64 handling. From: Chris Torek >The SPARC64 kernel code for PTRACE_SETFPREGS64 appears to be an exact copy >of that for PTRACE_GETFPREGS64. This means that gdbserver and native >64-bit GDB cannot set floating-point registers. It looks like a simple typo. Signed-off-by: David S.
