Description Elton Algera 2004-05-20 02:53:24 UTC 
When including SMP support in the Usermode 2.6.4-uml1-r0 kernel, compile fails.
In /usr/src/linux-2.6.4-uml1-r0/include/linux/spinlock.h a conditional include of <asm/spinlock.h> is done :

#ifdef CONFIG_SMP
#include <asm/spinlock.h>
.....

The asm/spinlock.h file does not exist in the tree.

Reproducible: Always
Steps to Reproduce:
1. make ARCH=um menuconfig
2. In menuconfig, include SMP support
3. make ARCH=um

Actual Results:  
Give loads of errors, including the message: <asm/spinlock.h>: no such file or
directory.

Expected Results:  
compile the kernel
Comment 1 Tim Yamin (RETIRED) gentoo-dev 2004-06-20 13:03:25 UTC 
Do you still get this issue with usermode-sources-2.6.6-r1?
Comment 2 John Herdy 2004-06-23 03:28:22 UTC 
Still doesn't work with usermode-sources-2.6.6-r1 and Highmem doesn't work either.
Also note that if I disable Tracing thread support, Enable kernel debugging symbols or Enable ptrace proxy I'm not able to build the kernel.

Comment 3 Daniel Drake (RETIRED) gentoo-dev 2004-08-21 14:56:09 UTC 
It seems there are quite a few compilation issues with this patchset, unfortunately they appear to be upstream issues. Making bug 49277 the place to monitor any progress. FYI, the new UML 2.6.7-2 patch still fails to compile with SMP support.
