x86/boot/e820: Rename sanitize_e820_table() to e820__update_table()
sanitize_e820_table() is a minor misnomer in that it suggests that the E820 table requires sanitizing - which implies that it will only do anything if the E820 table is irregular (not sane). That is wrong, because sanitize_e820_table() also does a very regular sorting of the E820 table, which is a necessity in the basic append-only flow of E820 updates the kernel is allowed to perform to it. So rename it to e820__update_table() to include that purpose as well. This also lines up all the table-update functions into a coherent naming family: int e820__update_table(struct e820_entry *biosmap, int max_nr_map, u32 *pnr_map); void e820__update_table_print(void); void e820__update_table_firmware(void); No change in functionality.
