work around hipe_mfa_info_table lock omission
HiPE maintains per-MFA information such as native code entry point in a table. This table was thought to be read-only at runtime, except when the loader populates it, so it employed no locking. That turned out to be incorrect: if there is an apply of a previously unseen MFA, a native code stub for that MFA is created and recorded in the table, causing it to grow. Work around this for now by slapping a mutex around accesses to that table. Signed-off-by: Mikael Pettersson <[email protected]>
