Function its_alloc_tables() maintains two local variables, "order" and
and "alloc_size", to hold memory size that has been allocated to
ITS_BASEn. We don't always refresh the variable alloc_size whenever
value of the variable order changes, causing the following two
problems.
- Cache flush operation with size more than required.
- Information reported by pr_info is not correct.
Use a helper macro that converts page order to size in bytes instead of
variable "alloc_size" to fix both the problems.
