[Xen-devel] [PATCH v1 4/7] page-alloc: Remove dependency on __LINE__ for release builds

[Ross Lagerwall <ross.lagerwall@xxxxxxxxxx>]

When using xsplice, use of __LINE__ can generate spurious changes in
functions due to embedded line numbers.  For release builds, remove the
use of these line numbers in BOOT_BUG_ON() and print the current text
address instead.
