+/**
+ * Worker for bs3CpuBasic2_RaiseXcpt0e_c32 that does the actual testing.
+ *
+ * Caller does all the cleaning up.
+ *
+ * @returns Error count.
+ * @param   bMode               The mode to test.
+ * @param   pbTestOrg           Pointer to the actual memory allocation (low
+ *                              memory) where it is identity mapped (virtual
+ *                              address == physical address).  This function
+ *                              will not touch paging structures here.
+ * @param   pbTest              Pointer to the aliased allocation in high
+ *                              memory.  This is aligned on a gigabyte boundrary
+ *                              so that 1GB pages can be tested (later).
+ * @param   cbTest              The size of the memory allocated for testing.
+ * @param   pPgInfo             The paging info for @a pbTest.
