page_is_pfmemalloc() is used mostly by networking drivers. It doesn't
write anything to the struct page itself, so constify its argument and
a bunch of callers and wrappers around this function in drivers.
In Page Pool core code, it can be simply inlined instead.

Userspace Execution protection and fast syscall entry were implemented

leading to syscall entry missing userspace execution protection.
On syscall entry, execution of user space memory must be

If the code can use a stack in vm area, it can also use a
stack in linear space.
Simplify code by removing old non VMAP stack code on PPC32 in syscall.
That means the data translation is now re-enabled early in

Subject: [PATCH]
Now that we are using rfi instead of mtmsr to reactivate MMU, it is
possible to reorder instructions and avoid the need to use CTR for
stashing SRR0.
null_syscall on 8xx is reduced by 3 cycles (283 => 280 cycles).

On 40x and 8xx, kernel text is pinned.
On book3s/32, kernel text is mapped by BATs.
Enable instruction translation at the same time as data translation, it
makes things simpler.
MSR_RI can also be set at the same time because srr0/srr1 are already
saved and r1 is set properly.

Hi Vinod,
This patch series adds support for the Direct Memory Access Controller
variant in the Renesas R-Car V3U (R8A779A0) SoC, to both DT bindings and
driver.
Changes compared to v1:
- Add Reviewed-by,
- Put the full loop control of for_each_rcar_dmac_chan() on a single
line,
Add and helper macro for iterating over all DMAC channels, taking into
account the channel mask. Use it where appropriate, to simplify code.
Restore "reverse Christmas tree" order of local variables while adding a
new variable.

Move kdb environment related get/set APIs to a separate file in order
