[PATCH 5.4 110/475] perf/x86/intel/pt: Fix address filter config for 32-bit kernel

[Greg Kroah-Hartman]

From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

[ Upstream commit e5524bf1047eb3b3f3f33b5f59897ba67b3ade87 ]

Change from shifting 'unsigned long' to 'u64' to prevent the config bits
being lost on a 32-bit kernel.

Fixes: eadf48cab4b6b0 ("perf/x86/intel/pt: Add support for address range filtering in PT")
