d7cf83fcaf powerpc/powernv: Move opal-api.h closer to the Skiboot version
This commit gets opal-api.h to mostly match the version in Skiboot as of
commit ea7d806ab0ba.

The exceptions are things which are not (currently) used in Linux.

Most of this is just whitespace and a few things moving around. I think
the diff is readable.

Also OpalMessageType became opal_msg_type, requiring a change in the
Linux code.

Finally Skiboot and Linux disagree on CAPI vs CXL, because CAPI means
something else in Linux. To handle that we just point the Linux wrapper,
which is named "cxl" to the OPAL token OPAL_PCI_SET_PHB_CAPI_MODE.

d800ba1218 powerpc/powernv: Move OPAL API definitions to opal-api.h
We'd like to get to the stage where the OPAL API is defined in a header
that is identical between Linux and Skiboot.

As step one, split the bits that actually define the API into
opal-api.h. The Linux specific parts stay in opal.h.

7f4eec3953 powerpc: Delete unnecessary checks before kfree()
The kfree() function tests whether its argument is NULL and then returns
immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

df99e6eb3f powerpc: Change vsrX register defines to vsX to match gcc and glibc
As our various loops (copy, string, crypto etc) get more complicated,
we want to share implementations between userspace (eg glibc) and
the kernel. We also want to write userspace test harnesses to put
in tools/testing/selftest.

One gratuitous difference between userspace and the kernel is the
VSX register definitions - the kernel uses vsrX whereas gcc uses
vsX.

1ee89c519a The clk fixes for 4.0-rc4 comprise three themes. First are the usual
driver fixes for new regressions since v3.19. Second are fixes to the
 common clock divider type caused by recent changes to how we round clock
 rates. This affects many clock drivers that use this common code.
 Finally there are fixes for drivers that improperly compared struct clk
 pointers (drivers must not deref these pointers). While some of these
 drivers have done this for a long time, this did not cause a problem
 until we started generating unique struct clk pointers for every
 consumer. A new function, clk_is_match was introduced to get these
 drivers working again and they are fixed up to no longer deref the
 pointers themselves.

If UEFI Runtime Services are available, they are preferred over direct

For the reset case, we need to hook into machine_restart(), as the

285994a62c arm64: Invalidate the TLB corresponding to intermediate page table levels
The ARM architecture allows the caching of intermediate page table
levels and page table freeing requires a sequence like:

	pmd_clear()
	TLB invalidation
	pte page freeing

With commit 5e5f6dc105 (arm64: mm: enable HAVE_RCU_TABLE_FREE logic),
the page table freeing batching was moved from tlb_remove_page() to
tlb_remove_table(). The former takes care of TLB invalidation as this is
also shared with pte clearing and page cache page freeing. The latter,
however, does not invalidate the TLBs for intermediate page table levels
as it probably relies on the architecture code to do it if required.
When the mm->mm_users < 2, tlb_remove_table() does not do any batching
and page table pages are freed before tlb_finish_mmu() which performs
the actual TLB invalidation.

This patch introduces __tlb_flush_pgtable() for arm64 and calls it from
the {pte,pmd,pud}_free_tlb() directly without relying on deferred page
table freeing.

a51139fdbc ARM: imx: fix struct clk pointer comparing
Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers.  That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get().  This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place.  The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.

That said, the struct clk pointer comparing in the code doesn't work any
more.  Call helper function clk_is_match() instead to fix the problem.

Commit 7ef077a8ad ("usb: isp1760: Move driver from drivers/usb/host/
to drivers/usb/isp1760/") moved the isp1760 driver and changed the
Kconfig option. This makes CONFIG_USB_ISP1760_HCD not selectable
directly anymore. This results in driver being not compiled in when
using vexpress_defconfig and the USB is non-functional.

This patch updates the CONFIG_USB_ISP1760_HCD to CONFIG_USB_ISP1760 to
get back USB functional on vexpress platforms.

05d6a08847 ARM: at91/dt: at91sam9261: fix clocks and clock-names in udc definition
Peripheral clock is named pclk and system clock is named hclk (those are
the names expected by the at91_udc driver).

Drop the deprecated usb_clk (formerly used to configure the usb clock rate
which is now directly configurable through hclk).

39ed853a24 Power management and ACPI fixes for v4.0-rc3
- Fix ACPI resources management problems introduced by the recent
    rework of the code in question (Jiang Liu) and a build issue
    introduced by those changes (Joachim Nilsson).
 
  - Fix a recent suspend-to-idle regression on systems where entering
    idle states causes local timers to stop, prevent suspend-to-idle
    from crashing in restricted configurations (no cpuidle driver,
    cpuidle disabled etc.) and clean up the idle loop somewhat while
    at it (Rafael J Wysocki).
 
  - Fix build problem in the cpufreq ppc driver (Geert Uytterhoeven).
 
  - Allow the ACPI backlight driver module to be loaded if ACPI is
    disabled which helps the i915 driver in those configurations
    (stable-candidate) and change the code to help debug unusual use
    cases (Chris Wilson).
 
  - Wakeup IRQ management changes in v3.18 caused some drivers on the
    at91 platform to trigger a warning from the IRQ core related to
    an unexpected combination of interrupt action handler flags.
    However, on at91 a timer IRQ is shared with some other devices
    (including system wakeup ones) and that leads to the unusual
    combination of flags in question.  To make it possible to avoid
    the warning introduce a new interrupt action handler flag (which
    can be used by drivers to indicate the special case to the core)
    and rework the problematic at91 drivers to use it and work as
    expected during system suspend/resume.  From Boris Brezillon,
    Rafael J Wysocki and Mark Rutland.
 
  - Clean up the generic power domains subsystem's debugfs interface

38f5c8ba30 ARM: dts: OMAP5: fix polling intervals for thermal zones
OMAP4 has a finer counter granularity, which allows for a delay of 1000ms
in the thermal zone polling intervals. OMAP5 has a different counter
mechanism, which allows at maximum a 500ms timer. Adjust the cpu thermal
zone polling interval accordingly.

Without this patch, the polling interval information is simply ignored,
and the following thermal warnings are printed during boot (assuming
thermal is enabled);
