5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andre Przywara <andre.przywara@xxxxxxx>
[ Upstream commit 96dddb7b9406259baace9a1831e8da155311be6f ]
When checking MTE tags, we print some diagnostic messages when the tests
fail. Some variables uses there are "longs", however we only use "%x"
for the format specifier.
Update the format specifiers to "%lx", to match the variable types they
are supposed to print.
Fixes: f3b2a26ca78d ("kselftest/arm64: Verify mte tag inclusion via prctl")
