of: overlay: update phandle cache on overlay apply and remove
A comment in the review of the patch adding the phandle cache said that
the cache would have to be updated when modules are applied and removed.
This patch implements the cache updates.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull more overflow updates from Kees Cook:
"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of
manual whitespace updates in the patches as well.
Summary:
- Error path bug fix for overflow tests (Dan)
- Additional struct_size() conversions (Matthew, Kees)
- Explicitly reported overflow fixes (Silvio, Kees)
- Add missing kvcalloc() function (Kees)
- Treewide conversions of allocators to use either 2-factor argument
variant when available, or array_size() and array3_size() as needed
(Kees)"

treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window. We stage them in a separate branch and if things look good, we still send them up -- and that's the case here. This is mostly DT additions for Renesas platforms, adding IP block descriptions for existing and new SoCs. There are also some driver updates for Qualcomm platforms for SMEM/QMI and GENI, which is their generalized serial protocol interface. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCVIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3KOcP/3O2+igstXt5rhemITdyi8rHkrIHPgetf25e ISBQzYrQOHV21SqT4le/Gk2CCQ6iX5Nv2DYoIrCzFWi/4DoDxXvryczQLla02Nru i8fcuxae7aFGW7/97G1+cATGPwuBLPiKXs6Wj01sKHeLBja5Det7eoXuHag7Y/Lo 4ls9wNZybMdlCcGm6+ULdj+XUdRyYUhOQQYvnPm2Q8hEkM+AiwLOBJTFwef9P5ad mX37kPDfwCxYwQXgZB1RkK/oJu0G2mTZXmGH5o+s+9yAyAupCQhmHGOrt3mlOf7j tLRlSgarJlO/QGIpJmDuCcxt3msD3OMd2dPbdgwojdpvycOU8EVWYLmCRpyIWQXv DCv9A9Gp4KlJnwxheVegBtilRA1aKsGuarWq6yeyOFt8N23Bgg/IjYKI9JF5+hPD M4q1oVAbUlfWb79rEc+TB0d7euREBkNn4TzzKMSOyP3eGUrXR0WUlq2A2VLxgIJo cx/ufY7CwvRgV+VxfhRbca+FmwDnu7uqzwLe73Ys2hnsuv8hXEtc+vSybqKqxVeU nHpWAqwaWhijlJiGq722vPo8avrLwjsxRwimogvijtesz9ZlTqrGtjkg61+eN2h8 eeuyRAsMUfVRiKuL3W+q4s0rzIauormnKsvRScKVyNFuiJfrfYb1odLoDGaOV/9G dQ7hA7TW =RUL0 -----END PGP SIGNATURE----- Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late updates from Olof Johansson: "This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window.

dma-mapping updates for 4.18:
- replaceme the force_dma flag with a dma_configure bus method.
(Nipun Gupta, although one patch is іncorrectly attributed to me
due to a git rebase bug)
- use GFP_DMA32 more agressively in dma-direct. (Takashi Iwai)
- remove PCI_DMA_BUS_IS_PHYS and rely on the dma-mapping API to do the
right thing for bounce buffering.
- move dma-debug initialization to common code, and apply a few cleanups
to the dma-debug code.
- cleanup the Kconfig mess around swiotlb selection
- swiotlb comment fixup (Yisheng Xie)
- a trivial swiotlb fix. (Dan Carpenter)
- support swiotlb on RISC-V. (based on a patch from Palmer Dabbelt)
- add a new generic dma-noncoherent dma_map_ops implementation and use
it for arc, c6x and nds32.
- improve scatterlist validity checking in dma-debug. (Robin Murphy)
- add a struct device quirk to limit the dma-mask to 32-bit due to
bridge/system issues, and switch x86 to use it instead of a local
hack for VIA bridges.
- handle devices without a dma_mask more gracefully in the dma-direct
code.

of: platform: stop accessing invalid dev in of_platform_device_destroy
Immediately after the platform_device_unregister() the device will be cleaned up. Accessing the freed pointer immediately after that will crash the system. Found this bug when kernel is built with CONFIG_PAGE_POISONING and testing loading/unloading audio drivers in a loop on Qcom platforms. Fix this by moving of_node_clear_flag() just before the unregister calls. Below is the crash trace: Unable to handle kernel paging request at virtual address 6b6b6b6b6b6c03 Mem abort info: ESR = 0x96000021 Exception class = DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 Data abort info: ISV = 0, ISS = 0x00000021 CM = 0, WnR = 0 [006b6b6b6b6b6c03] address between user and kernel address ranges Internal error: Oops: 96000021 [#1] PREEMPT SMP Modules linked in: CPU: 2 PID: 1784 Comm: sh Tainted: G W 4.17.0-rc7-02230-ge3a63a7ef641-dirty #204 Hardware name: Qualcomm Technologies, Inc.

The OPP tables are present as separate nodes, whose phandle is used in the "operating-points-v2" property of devices. Currently the OF core creates a device for the OPP table unconditionally, which is not used by any kernel code. This patch creates another OF device_id table for the nodes which must be skipped while creating devices and OPP is the only user of it for now.

of/numa: drop export of of_node_to_nid
The "generic" implementation of of_node_to_nid is only used by arm64 and only in built-in code, so remove its export. Any device with a struct device should be able to use dev_to_node() instead. Also, exporting of_node_to_nid doesn't actually work if we build a module on an arch that doesn't select OF_NUMA nor provide its own of_node_to_nid implementation.

seq_put_decimal_ull_w(m, str, val, width) prints a decimal number with a

It is equivalent of seq_printf(m, "%s%*d", str, width, val), but it
works much faster.

kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers
GNU Make automatically deletes intermediate files that are updated
in a chain of pattern rules.
Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
Example 2) %.o <- %.c <- %.c_shipped
A couple of makefiles mark such targets as .PRECIOUS to prevent Make
from deleting them, but the correct way is to use .SECONDARY.
.SECONDARY
Prerequisites of this special target are treated as intermediate
files but are never automatically deleted.
.PRECIOUS
When make is interrupted during execution, it may delete the target
file it is updating if the file was modified since make started.
If you mark the file as precious, make will never delete the file
if interrupted.
Both can avoid deletion of intermediate files, but the difference is
the behavior when Make is interrupted; .SECONDARY deletes the target,
but .PRECIOUS does not.
The use of .PRECIOUS is relatively rare since we do not want to keep
partially constructed (possibly corrupted) targets.
Another difference is that .PRECIOUS works with pattern rules whereas
.SECONDARY does not.
.PRECIOUS: $(obj)/%.lex.c
works, but
.SECONDARY: $(obj)/%.lex.c
has no effect. However, for the reason above, I do not want to use
.PRECIOUS which could cause obscure build breakage.
The targets specified as .SECONDARY must be explicit. $(targets)
contains all targets that need to include .*.cmd files. So, the
intermediates you want to keep are mostly in there. Therefore, mark
$(targets) as .SECONDARY. It means primary targets are also marked
as .SECONDARY, but I do not see any drawback for this.
I replaced some .SECONDARY / .PRECIOUS markers with 'targets'. This
will make Kbuild search for non-existing .*.cmd files, but this is
not a noticeable performance issue.

kbuild: add %.dtb.S and %.dtb to 'targets' automatically
Another common pattern that consists of chained commands is to compile a DTB as binary data into the kernel image or a module. It is used in several places in the source tree. Support it in the core Makefile. $(call if_changed,dt_S_dtb) is more suitable than $(call cmd,dt_S_dtb) in case cmd_dt_S_dtb is changed in the future.

of: Add missing I/O range exception for indirect-IO devices
There are some special ISA/LPC devices that work on a specific I/O range where it is not correct to specify a 'ranges' property in the DTS parent node as CPU addresses translated from DTS node are only for memory space on some architectures, such as ARM64. Without the parent 'ranges' property, of_translate_address() returns an error. Here we add special handling for this case. During the OF address translation, some checking will be performed to identify whether the device node is registered as indirect-IO. If it is, the I/O translation will be done in a different way from that one of PCI MMIO. In this way, the I/O 'reg' property of the special ISA/LPC devices will be parsed correctly.

of_net: Implement of_get_nvmem_mac_address helper
It's common practice to store MAC addresses for network interfaces into nvmem devices. However the code to actually do this in the kernel lacks, so this patch adds of_get_nvmem_mac_address() for drivers to obtain the address from an nvmem cell provider. This is particulary useful on devices where the ethernet interface cannot be configured by the bootloader, for example because it's in an FPGA.

The overlay_data_apply() declaration is outside of the #ifdef that contains

of: unittest: remove unneeded local return value variables
A common pattern in many unittest functions is to save the return
value of a function in a local variable, then test the value of
the local variable, without using that return value for any further
purpose. Remove the local return value variable for these cases.
A second common pattern is:
ret = some_test_function(many, parameters, ...);
if (unittest(ret == 0, "error message format", ...))
return;
This pattern is more clear when the local variable 'ret' is used, due
to the long lines caused by the parameters to the test function and
the long format and data parameters of unittest(). The local
variable is retained in these cases.

of: cache phandle nodes to reduce cost of of_find_node_by_phandle()
Create a cache of the nodes that contain a phandle property. Use this cache to find the node for a given phandle value instead of scanning the devicetree to find the node. If the phandle value is not found in the cache, of_find_node_by_phandle() will fall back to the tree scan algorithm. The cache is initialized in of_core_init(). The cache is freed via a late_initcall_sync() if modules are not enabled. If the devicetree is created by the dtc compiler, with all phandle property values auto generated, then the size required by the cache could be 4 * (1 + number of phandles) bytes. This results in an O(1) node lookup cost for a given phandle value. Due to a concern that the phandle property values might not be consistent with what is generated by the dtc compiler, a mask has been added to the cache lookup algorithm. To maintain the O(1) node lookup cost, the size of the cache has been increased by rounding the number of entries up to the next power of two. The overhead of finding the devicetree node containing a given phandle value has been noted by several people in the recent past, in some cases with a patch to add a hashed index of devicetree nodes, based on the phandle value of the node. One concern with this approach is the extra space added to each node. This patch takes advantage of the phandle property values auto generated by the dtc compiler, which begin with one and monotonically increase by one, resulting in a range of 1..n for n phandle values. This implementation should also provide a good reduction of overhead for any range of phandle values that are mostly in a monotonic range. Performance measurements by Chintan Pandya <cpandya@codeaurora.org> of several implementations of patches that are similar to this one suggest an expected reduction of boot time by ~400ms for his test system. If the cache size was decreased to 64 entries, the boot time was reduced by ~340 ms. The measurements were on a 4.9.73 kernel for arch/arm64/boot/dts/qcom/sda670-mtp.dts, contains 2371 nodes and 814 phandle values.

of: change overlay apply input data from unflattened to FDT
Move duplicating and unflattening of an overlay flattened devicetree
(FDT) into the overlay application code. To accomplish this,
of_overlay_apply() is replaced by of_overlay_fdt_apply().
The copy of the FDT (aka "duplicate FDT") now belongs to devicetree
code, which is thus responsible for freeing the duplicate FDT. The
caller of of_overlay_fdt_apply() remains responsible for freeing the
original FDT.
The unflattened devicetree now belongs to devicetree code, which is
thus responsible for freeing the unflattened devicetree.
These ownership changes prevent early freeing of the duplicated FDT
or the unflattened devicetree, which could result in use after free
errors.
of_overlay_fdt_apply() is a private function for the anticipated
overlay loader.
Update unittest.c to use of_overlay_fdt_apply() instead of
of_overlay_apply().
Move overlay fragments from artificial locations in
drivers/of/unittest-data/tests-overlay.dtsi into one devicetree
source file per overlay. This led to changes in
drivers/of/unitest-data/Makefile and drivers/of/unitest.c.
- Add overlay directives to the overlay devicetree source files so
that dtc will compile them as true overlays into one FDT data
chunk per overlay.
- Set CFLAGS for drivers/of/unittest-data/testcases.dts so that
symbols will be generated for overlay resolution of overlays
that are no longer artificially contained in testcases.dts
- Unflatten and apply each unittest overlay FDT using
of_overlay_fdt_apply().
- Enable the of_resolve_phandles() check for whether the unflattened
overlay is detached. This check was previously disabled because the
overlays from tests-overlay.dtsi were not unflattened into detached
trees.
- Other changes to unittest.c infrastructure to manage multiple test
FDTs built into the kernel image (access by name instead of
arbitrary number).
- of_unittest_overlay_high_level(): previously unused code to add
properties from the overlay_base devicetree to the live tree
was triggered by the restructuring of tests-overlay.dtsi and thus
testcases.dts. This exposed two bugs: (1) the need to dup a
property before adding it, and (2) property 'name' is
auto-generated in the unflatten code and thus will be a duplicate
in the __symbols__ node - do not treat this duplicate as an error.

of: Support parsing phandle argument lists through a nexus node
Platforms like 96boards have a standardized connector/expansion
slot that exposes signals like GPIOs to expansion boards in an
SoC agnostic way. We'd like the DT overlays for the expansion
boards to be written once without knowledge of the SoC on the
other side of the connector. This avoids the unscalable
combinatorial explosion of a different DT overlay for each
expansion board and SoC pair.
We need a way to describe the GPIOs routed through the connector
in an SoC agnostic way. Let's introduce nexus property parsing
into the OF core to do this. This is largely based on the
interrupt nexus support we already have. This allows us to remap
a phandle list in a consumer node (e.g. reset-gpios) through a
connector in a generic way (e.g. via gpio-map). Do this in a
generic routine so that we can remap any sort of variable length
phandle list.
Taking GPIOs as an example, the connector would be a GPIO nexus,
supporting the remapping of a GPIO specifier space to multiple
GPIO providers on the SoC. DT would look as shown below, where
'soc_gpio1' and 'soc_gpio2' are inside the SoC, 'connector' is an
expansion port where boards can be plugged in, and
'expansion_device' is a device on the expansion board.
soc {
soc_gpio1: gpio-controller1 {
#gpio-cells = <2>;
};
soc_gpio2: gpio-controller2 {
#gpio-cells = <2>;
};
};
connector: connector {
#gpio-cells = <2>;
gpio-map = <0 0 &soc_gpio1 1 0>,
<1 0 &soc_gpio2 4 0>,
<2 0 &soc_gpio1 3 0>,
<3 0 &soc_gpio2 2 0>;
gpio-map-mask = <0xf 0x0>;
gpio-map-pass-thru = <0x0 0x1>
};
expansion_device {
reset-gpios = <&connector 2 GPIO_ACTIVE_LOW>;
};
The GPIO core would use of_parse_phandle_with_args_map() instead
of of_parse_phandle_with_args() and arrive at the same type of
result, a phandle and argument list. The difference is that the
phandle and arguments will be remapped through the nexus node to
the underlying SoC GPIO controller node. In the example above,
we would remap 'reset-gpios' from <&connector 2 GPIO_ACTIVE_LOW>
to <&soc_gpio1 3 GPIO_ACTIVE_LOW>.
