6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann arnd@arndb.de
commit 48a136639ec233614a61653e19f559977d5da2b5 upstream.
On 32-bit architectures, the new calculation causes a build failure:
ld.lld-21: error: undefined symbol: __aeabi_uldivmod
Since neither value is ever larger than a register, cast both sides into a uintptr_t.
