Subject: modpost: Fix processing of CRCs on 32-bit build machines
From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>
commit fb27e70f6e408dee5d22b083e7a38a59e6118253 upstream.
modpost now reads CRCs from .*.cmd files, parsing them using strtol().
This is inconsistent with its parsing of Module.symvers and with their
definition as *unsigned* 32-bit values.
strtol() clamps values to [LONG_MIN, LONG_MAX], and when building on a
32-bit system this changes all CRCs >= 0x80000000 to be 0x7fffffff.
Change extract_crcs_for_object() to use strtoul() instead.
