sched/core: Remove unused prefetch_stack()

2017-03-03T00:45:38+00:00

prefetch_stack() is defined by IA64, but not actually used anywhere anymore.

Remove it.

ia64: move exports to definitions

2016-08-08T03:55:50+00:00

Here we have another kind of deviation from the default case -
a difference between exporting functions and non-functions.
EXPORT_DATA_SYMBOL... is really different from EXPORT_SYMBOL...
on ia64, and we need to use the right one when moving exports
from *.c where C compiler has the required information to
*.S, where we need to supply it manually.

parisc64 will be another one like that.

[IA64] Wire up kcmp syscall

2015-10-28T21:22:59+00:00

systemd > 218 fails to compile on ia64 with:

     error: ‘__NR_kcmp’ undeclared [1].

I've been told that this is because the kcmp syscall hasn't been wired up
for the ia64 arch [2].

The proposed patch thus wire up the kcmp syscall for the ia64 arch.

ia64: remove paravirt code

2015-06-10T21:26:32+00:00

All the ia64 pvops code is now dead code since both
xen and kvm support have been ripped out [0] [1]. Just
that no one had troubled to rip this stuff out. The only
useful remaining pieces were the old pvops docs but that
was recently also generalized and moved out from ia64 [2].

This has been run time tested on an ia64 Madison system.
