[MERGED] A bug in the NFS client that caused bogus access times with O_EXCL|O_CREAT opens was fixed. [MERGED] +Support for the 80386 processor has been removed from the GENERIC +kernel, as this code seriously pessimizes performance on other ia32 +processors. + +The I386_CPU kernel option to support the 80386 processor is now mutually +exclusive with support for other ia32 processors; this should slightly +improve performance on the 80386 due to the elimination of runtime +processor type checks. + +Custom kernels that will run on the 80386 can still be built by changing +the cpu options in the kernel configuration file to only include I386_CPU. 1.2.
