As suggested by paulus we can simplify the Data Stream Control Register
(DSCR) Facility Status and Control Register (FSCR) handling.
Firstly, we simplify the asm by using a rldimi.
Secondly, we now use the FSCR only to control the DSCR facility, rather
than both the FSCR and HFSCR. Users will se

Hi S.Saravanan,
Root complex's would normally interrupt a device via a PCIe write
to a register in a BAR on the end-point (or in extended configuration
space registers depending on the hardware implementation).
MPC8640 End point implements only the Type 0 header (Page 1116) . The
header implem

We plan to use the jump label in the cpu/mmu feature check on ppc.
This will need to include the jump_label.h in several very basic header
files of ppc which seems to be included by most of the other head
files implicitly or explicitly. But in the current jump_label.h,
it also include the "linux/wo
The mmu features are fixed once the probe of mmu features are done.
And the function mmu_has_feature() does be used in some hot path.
The checking of the mmu features for each time of invoking of
mmu_has_feature() seems suboptimal. This tries to reduce this
overhead of this check by using jump labe

The struct static_key will have a atomic_t type member no matter
whether jump label is enabled or not. We would include linux/atomic.h
when jump label is not enabled. But it also does make sense to include
this header file when jump label is enabled.

We plan to use jump label for cpu_has_feature. In order to implement
this we need to include the linux/jump_label_base.h in asm/cputable.h.
But it seems that asm/cputable.h is so basic header file for ppc that
it is almost included by all the other header files. The including of
the linux/jump_labe
Inspired by Benjamin Herrenschmidt, this patch series try to reduce the
cpu/mmu feature checking overhead by using jump label. The following is
the difference of the run path of cpu_has_feature between before and after
applying these patches:
