I built 2.6.5-rc2 and it's running fine on a amd64 installed with
Fedora Core 1. Unfortunately the mm1 patch is giving me an assembler
error when macros with args are invoked in:

For example, the first error at line 184 is the invocation
of the SAVE_ARGS macro:
178 ENTRY(system_call)
179 CFI_STARTPROC
180 swapgs
181 movq %rsp,%gs:pda_oldrsp
182 movq %gs:pda_kernelstack,%rsp
183 sti
184 SAVE_ARGS 8,1 <------- HERE
185 movq %rax,ORIG_RAX-ARGOFFSET(%rsp)
186 movq %rcx,RIP-ARGOFFSET(%rsp)
187 GET_THREAD_INFO(%rcx)
The same code without the mm1 patch is identical.
