- In ntoskrnl_var.h, I had defined compat macros for
ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but
never used them. This is fortunate since they were stale. Fix them
to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that
calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this,
ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(),
which lives in subr_hal.o.)
- Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that
call hal_raise_irql() and hal_lower_irql().
- Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c.
- Along the way, I realised subr_ndis.c:ndis_lock() was not calling
hal_lock() correctly (it was using the FASTCALL2() wrapper when
in reality this routine is FASTCALL1()). Using the
ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually
caused any bugs since hal_lock() would have just ignored what
was in %edx, but it was still bogus.
This hides many of the uses of the FASTCALLx() macros which makes the
code a little cleaner. Should not have any effect on generated object
code, other than the one fix in ndis_lock().
