| |
3.2.83-rt121-rc1 stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@decadent.org.uk>
gcc warns about casting directly from a 32-bit pointer to u64. In the current rt patch series we cast to unsigned long to avoid the warning, but this fix hasn't been backported to all versions.
