linux-next: build failure after merge of the final tree (uprobestree related)

[Stephen Rothwell]

Hi Srikar,

After merging the uprobes tree, today's linux-next build (sparc64
defconfig) failed like this:

In file included from include/linux/mm_types.h:15:0,
                 from include/linux/kmemcheck.h:4,
                 from include/linux/skbuff.h:18,
                 from net/8021q/vlan_core.c:1:
include/linux/uprobes.h: In function 'register_uprobe':
include/linux/uprobes.h:148:10: error: 'ENOSYS' undeclared (first use in this function)

And several more.

Caused by commit fb16338b69cd ("register_unregister_uprobe" - "Uprobes:
register/unregister probes").

I have added this patch for today:

Subject: [PATCH] uprobes: using ENOSYS requires errno.h

Fixes this build problem:

In file included from include/linux/mm_types.h:15:0,
                 from include/linux/kmemcheck.h:4,
                 from include/linux/skbuff.h:18,
                 from net/8021q/vlan_core.c:1:
include/linux/uprobes.h: In function 'register_uprobe':
include/linux/uprobes.h:148:10: error: 'ENOSYS' undeclared (first use in this function)

when CONFIG_UPROBES is not defined.
