Applied, thanks
In future please do split this per driver, that helps..

I meant changing perf_evsel__append_filter() and callers in a separate
preparatory patch. Perhaps add and use:
int perf_evsel__append_tp_filter(struct perf_evsel *evsel, const char *filter)
{
return perf_evsel__append_filter(evsel, "(%s) && (%s)", filter);
}

It would be good to have a better explanation that "it's already
broken by some other commit". Is this a platform that never shipped
to end-users, or is it possible that someone out there actually
has a machine with one of these SoCs?

Well, you just used some function in some context which is not relevant to
the normal operation. So adding that mask() is just paranoia for no value.

STiD127 related code, which has never actually been supported

* [PATCH 14/19] pinctrl: st: Remove obsolete platforms from pinctrl-st dt doc
From: Peter Griffin @ 2016-09-14 13:27 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1473859677-9231-1-git-send-email-peter.griffin@linaro.org>
STiH415/6 SoC support is being removed from the kernel.
This patch updates the ST pinctrl dt doc and removes
references to these obsolete platforms. It also updates
the dt example to the currently supported STiH407
platform.

* [PATCH 13/19] pinctrl: st: Remove STiH415/6 SoC pinctrl driver support.

STiH415/6 SoC support is being removed from the kernel.
This patch updates the ST pinctrl driver and removes
references to these obsolete platforms. As some structures
referenced by STiH407 based configuration were shared with
STiH416 we update these names to match the remaining
supported platform.

* [PATCH 09/19] thermal: sti: Remove obsolete STiH416 platform support.
From: Peter Griffin @ 2016-09-14 13:27 UTC (permalink / raw)

In-Reply-To: <1473859677-9231-1-git-send-email-peter.griffin@linaro.org>
STiH415/6 SoC support is being removed from the kernel.
This patch removes support from the thermal driver.
Also it updates the register defines and removes
the SoC and die prefix as neither of these are relevant
in the context of STiH407 based silicon (STiH415/6 were
dual die SoCs with an MPE die and SAS die).

-This file contains documentation for the usb phy found in STiH415/6 SoCs from
-STMicroelectronics.
-
-Required properties:
-- compatible : should be "st,stih416-usb-phy" or "st,stih415-usb-phy"

* [PATCH 01/19] phy: phy-miphy365x: Remove miphy365 driver and dt binding documentation.
From: Peter Griffin @ 2016-09-14 13:27 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <1473859677-9231-1-git-send-email-peter.griffin@linaro.org>
This phy is only used on STiH415/6 based silicon, and support for
these SoC's is being removed from the kernel.

-STMicroelectronics STi MIPHY365x PHY binding
-============================================
-
-This binding describes a miphy device that is used to control PHY hardware
-for SATA and PCIe.
-
-Required properties (controller (parent) node):
-- compatible : Should be "st,miphy365x-phy"
-- st,syscfg : Phandle / integer array property. Phandle of sysconfig group
- containing the miphy registers and integer array should contain
- an entry for each port sub-node, specifying the control
- register offset inside the sysconfig group.
-
-Required nodes : A sub-node is required for each channel the controller
- provides. Address range information including the usual
- 'reg' and 'reg-names' properties are used inside these
- nodes to describe the controller's topology. These nodes
- are translated by the driver's .xlate() function.
-
-Required properties (port (child) node):
-- #phy-cells : Should be 1 (See second example)
- Cell after port phandle is device type from:
- - PHY_TYPE_SATA
- - PHY_TYPE_PCI
-- reg : Address and length of register sets for each device in
- "reg-names"
-- reg-names : The names of the register addresses corresponding to the
- registers filled in "reg":
- - sata: For SATA devices
- - pcie: For PCIe devices
-
-Optional properties (port (child) node):
-- st,sata-gen : Generation of locally attached SATA IP. Expected values
- are {1,2,3). If not supplied generation 1 hardware will
- be expected
-- st,pcie-tx-pol-inv : Bool property to invert the polarity PCIe Tx (Txn/Txp)
-- st,sata-tx-pol-inv : Bool property to invert the polarity SATA Tx (Txn/Txp)
-
-Example:
-
- miphy365x_phy: miphy365x at fe382000 {
- compatible = "st,miphy365x-phy";
- st,syscfg = <&syscfg_rear 0x824 0x828>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- phy_port0: port at fe382000 {
- reg = <0xfe382000 0x100>, <0xfe394000 0x100>;
- reg-names = "sata", "pcie";
- #phy-cells = <1>;
- st,sata-gen = <3>;
- };
-
- phy_port1: port at fe38a000 {
- reg = <0xfe38a000 0x100>, <0xfe804000 0x100>;;
- reg-names = "sata", "pcie", "syscfg";
- #phy-cells = <1>;
- st,pcie-tx-pol-inv;
- };
- };
-
-Specifying phy control of devices
-=================================
-
-Device nodes should specify the configuration required in their "phys"
-property, containing a phandle to the phy port node and a device type.
-
-Example:
-
-#include <dt-bindings/phy/phy.h>
-
- sata0: sata at fe380000 {
- ...
- phys = <&phy_port0 PHY_TYPE_SATA>;
- ...
- };

* [PATCH 00/19] [RESEND] Remove STiH415 and STiH416 SoC platform support
From: Peter Griffin @ 2016-09-14 13:27 UTC (permalink / raw)
To: linux-arm-kernel
Resending due to incorrect Cc tags.
ST have sent patches which remove clock support for these SoCs [1]
which once applied mean the platform will no longer boot.
This series cleans up various STi platform drivers which have
support for these SoC's, by removing code, and updating the DT
documentation accordingly. Some drivers such as miphy365 and
stih41x-usb can be removed completely because the IP is only
found on these legacy SoC's.
Once this series is applied, drm display driver, and ALSA SoC
are the main two remaining references to the legacy SoCs, other
than clocks which already have patches on the ML.
regards,
Peter.

It might look similar, but at different levels (iommu_domain vs.
iova_domain) and with the opposite intent. The dm_region prot flag is
just the standard flag as passed to iommu_map() - trying to map a region
with no access in an empty pagetable isn't going to achieve anything
anyway (it's effectively unmapping addresses that are already unmapped).
But for this case, even if you _did_ map something in the pagetable
(i.e. the iommu_domain), it wouldn't make any difference, because the
thing we're mitigating against is handing out addresses which are going
to cause a device's accesses to blow up inside the PCI root complex
without ever even reaching the IOMMU. In short, dm_regions are about
"these addresses are already being used for DMA, so make sure the IOMMU
API doesn't block them", whereas reserved ranges are about "these
addresses are unusable for DMA, so make sure the DMA API can't allocate
them".
