read_current_timer is used in the get_cycles() function when
|
||
|
|
ARM_ARCH_TIMER is set, and that function can be inlined into
|
||
|
|
driver modules, so we should export the function to avoid
|
||
|
|
errors like
|
||
|
|
|
||
|
|
ERROR: "read_current_timer" [drivers/video/udlfb.ko] undefined!
|

ERROR: "read_current_timer" [crypto/tcrypt.ko] undefined!
