The arch/m68k/lib versions of the libgcc functions: ashldi3, ashrdi3 and lshrdi3 were taken directly from an older version of gcc. We can use the kernel's own generic lib versions of these - they are virtually identical. Switch to those and remove the m68k local ones. Signed-off-by:

strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of sizeof(dest).

Replace the (incorrect) external declarations by an inclusion of the appropriate header file. Semantically, the "src" parameters of the various fp_*() functions are constant. However, they cannot actually be const as most of these functions perform a normalization step first. As the fp_one constant passed to fp_add() is already normalized, it is safe to cast away its constness when making the function call. Signed-off-by:

Pull tracing fixes from Steven Rostedt: - Fix the "bytes" output of the per_cpu stat file The tracefs/per_cpu/cpu*/stats "bytes" was giving bogus values as the accounting was not accurate. It is suppose to show how many used bytes are still in the ring buffer, but even when the ring buffer was empty it would still show there were bytes used. - Fix a bug in eventfs where reading a dynamic event directory (open) and then creating a dynamic event that goes into that diretory screws up the accounting. On close, the newly created event dentry will get a "dput" without ever having a "dget" done for it. The fix is to allocate an array on dir open to save what dentries were actually "dget" on, and what ones to "dput" on close. * tag 'trace-v6.6-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Remember what dentries were created on dir open ring-buffer: Fix bytes info in per_cpu buffer stats
