2006-07-11Keep hashed user tokens, with the following changes:Thomas Hellstrom
32-bit physical device addresses are mapped directly to user-tokens. No duplicate maps are allowed, and the addresses are assumed to be outside of the range 0x10000000 through 0x30000000. The user-token is identical to the 32-bit physical start-address of the map. 64-bit physical device addressed are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. Other map types, like upcoming TTM maps are mapped to user-tokens in the range 0x10000000 to 0x30000000 with page-size increments. The user_token should not be interpreted as an address. This keeps compatibility with buggy drivers, while still implementing a hashed map lookup. The SiS and via device driver major bumps are reverted.
