Hi,
I am trying to port User-mode-linux to Sparc64 architecture. I have the
debian(sid) on my host system with custom built 2.4.18 kernel. When I
try to generate some header file for UML that #included
<asm-sparc64/processor.h> file, I was getting parse errors for u64 data
types. When I changed all those U64 data-types to __u64 type, it fixed
the error. So, I was just wondering, whether it is the right thing to
do.
-Thanks in advance

If you want the 'u64' type, define __KERNEL__. That is what
every platform does, protect the types without underscores with
a __KERNEL__ ifdef.

Hi,
In asm-sparc64/processor.h (2.4.18), in thread_struct structure, there
are 3 fields:
u64 *user_cntd0, *user_cntd1;
u64 kernel_cntd0, kernel_cntd1;
u64 pcr_reg;
which are defined without #ifdef __KERNEL__ . I guess, this is a bug,
which needs fixing.
Thanks
-Regards

You shouldn't be including such kernel headers from userspace.
