x86: CPA: fix gbpages support in try_preserve_large_page
[ mingo@elte.hu: while gbpages cannot be enabled on mainline currently, keep the code uptodate and this fix is easy enough. ] Use correct page sizes and masks for GB pages in try_preserve_large_page() This prevents a boot hang on a GB capable system with CONFIG_DIRECT_GBPAGES enabled.
