powerpc: Use global register variable in <thread_pointer.h>
|
||
|
|
|
||
|
|
A local register variable is merely a compiler hint, and so not
|
||
|
|
appropriate in this context. Move the global register variable into
|
||
|
|
<thread_pointer.h> and include it from <tls.h>, as there can only
|
||
|
|
be one global definition for one particular register.
|
||
|
|
|
||
|
|
Fixes commit 8dbeb0561eeb876f557ac9eef5721912ec074ea5
|
||
|
|
("nptl: Add <thread_pointer.h> for defining __thread_pointer").
