Yazen Ghannam dd61b55d73 RAS/AMD/ATL: Fix bit overflow in denorm_addr_df4_np2() ... The hash_pa8 and hashed_bit values in denorm_addr_df4_np2() are currently defined as u8 types. These variables represent single bits. 'hash_pa8' is set based on logical AND operations using masks with more than 8 bits. So the calculated value will not fit in this variable. It will always be '0'. The 'hash_pa8' check later in the function will fail which produces incorrect results for some cases. Change these variables to bool type. This clarifies that they are single bit values. Also, this allows the compiler to ensure they hold the proper results. Remove an unnecessary shift operation. [ bp: Remove the unnecessary brackets in the else-branch of the hash_pa8 assignment. ] Fixes: 3f3174996b ("RAS: Introduce AMD Address Translation Library") Signed-off-by: Yazen Ghannam <yazen.ghannam@amd.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://lore.kernel.org/r/20240222165449.23582-1-yazen.ghannam@amd.com		2024-02-26 13:05:12 +01:00
