Pull regulator fixes from Mark Brown:
"An addition to MAINTAINERS plus a fix for a nasty bootstrapping

If there is a long-standing request of one task locking up execution of
deferred requests, and the defer list contains requests of another task
(all files-less), then a potential execution of __io_uring_task_cancel()
by that another task will sleep until that first long-standing request
completion, and that may take long.
E.g.
tsk1: req1/read(empty_pipe) -> tsk2: req(DRAIN)
Then __io_uring_task_cancel(tsk2) waits for req1 completion.
It seems we even can manufacture a complicated case with many tasks
sharing many rings that can lock them forever.
Cancel deferred requests for __io_uring_task_cancel() as well.

When _PAGE_ACCESSED is not set, a minor fault is expected.
To do this, TLB miss exception ANDs _PAGE_PRESENT and _PAGE_ACCESSED
into the L2 entry valid bit.
To simplify the processing and reduce the number of instructions in
TLB miss exceptions, manage it as an APG bit and get it next to
_PAGE_GUARDED bit to allow a copy in one go. Then declare the
corresponding groups as handling all accesses as user accesses.
As the PP bits always define user as No Access, it will generate
a fault.

The kernel expects pte_young() to work regardless of CONFIG_SWAP.
Make sure a minor fault is taken to set _PAGE_ACCESSED when it
is not already set, regardless of the selection of CONFIG_SWAP.
This adds at least 3 instructions to the TLB miss exception
handlers fast path. Following patch will reduce this overhead.
Also update the rotation instruction to the correct number of bits
to reflect all changes done to _PAGE_ACCESSED over time.

Andreas reported that commit ee0a49a6870e ("powerpc/uaccess: Switch
__put_user_size_allowed() to __put_user_asm_goto()") broke
CLONE_CHILD_SETTID.
Further inspection showed that the put_user() in schedule_tail() was
missing entirely, the store not emitted by the compiler.
<.schedule_tail>:
mflr r0
std r0,16(r1)
stdu r1,-112(r1)
bl <.finish_task_switch>
ld r9,2496(r3)
cmpdi cr7,r9,0

addi r1,r1,112
ld r0,16(r1)
mtlr r0
blr
nop
nop
nop
bl <.__balance_callback>
b <.schedule_tail+0x1c>
Notice there are no stores other than to the stack. There should be a
stw in there for the store to current->set_child_tid.
This is only seen with GCC 4.9 era compilers (tested with 4.9.3 and
4.9.4), and only when CONFIG_PPC_KUAP is disabled.
When CONFIG_PPC_KUAP=y, the inline asm that's part of the isync()
and mtspr() inlined via allow_user_access() seems to be enough to
avoid the bug.
We already have a macro to work around this (or a similar bug), called
asm_volatile_goto which includes an empty asm block to tickle the
compiler into generating the right code. So use that.
With this applied the code generation looks more like it will work:
<.schedule_tail>:
mflr r0
std r31,-8(r1)
std r0,16(r1)
stdu r1,-144(r1)
