x86: Modify ENTRY in sysdep.h so that p2align can be specified
|
|
|
|
No bug.
|
|
|
|
This change adds a new macro ENTRY_P2ALIGN which takes a second
|
|
argument, log2 of the desired function alignment.
|
|
|
|
The old ENTRY(name) macro is just ENTRY_P2ALIGN(name, 4) so this
|
|
doesn't affect any existing functionality.
