Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

This moves the boardfile definition of the flash memory in the
Versatile board into the device tree. The flash was already
defined with the property "arm,versatile-flash" which was
not handled by the kernel: instead define it as compatible
also with "cfi-flash" so it detects properly, and delete the
corresponding boardfile code so we get a smooth transition.
The old compatible string "arm,versatile-flash" is reused to
indicate to the MTD physmap subsystem that this flash requires
special VPP handling. (See separate patch.)

With DT-only support now in place and most of the legacy code removed,
the separation of core.c and versatile_dt.c makes little sense. The
headers in mach include directory also have to move for multi-platform
support, but with a single .c file the remaining definitions needed can
also be moved into the versatile_dt.c.
In the move, the system registers and IB2 registers are converted to
run-time mappings and all register accesses converted to use
readl/writel.

With DT support for clocks, irqchips, timers, and PCI now in place, DT
based booting has feature parity with non-DT legacy boot. The final
piece is actually enabling common clock support on Versatile. Enabling
full DT support requires either removing the old Versatile clock code,
updating the legacy boot to use the common clock code, or making DT and
legacy boot mutually exclusive. Given that removing legacy boot code is
the goal anyway, I am going with the 1st option.

The definition
static const char *axxia_dt_match[] __initconst = {
...
defines a changable array of constant strings. That is you must not do:
*axxia_dt_match[0] = 'k';
but
axxia_dt_match[0] = "different string";
is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.
As the struct machine_desc member dt_compat is declared as
const char *const *dt_compat;
making the arrays const is the better alternative over changing all
annotations to __initdata.

ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.

This adds support for a VIC to be cascaded off another IRQ.
On the Integrator/AP logical module IM-PD1 there is a VIC
cascaded off the central FPGA IRQ controller so this is
needed for that to work out.
In order for the plug-in board to be able to register all
the devices with their IRQs relative to the offset of the
base obtained for the cascaded VIC, the base IRQ number
is passed back to the caller.

From Peter Maydell:
These patches fix a number of issues with the PCI controller
code for mach-versatile:
(1) The irq mapping matched neither hardware nor QEMU; we correct
it to match the hardware, which means it will also work on recent
(1.5 or later) QEMU.
(2) The code was confused between the PCI I/O window (at 0x43000000)
and the first PCI memory window (at 0x44000000), which meant that
PCI devices using PCI PIO rather than MMIO didn't work. This is
fixed (and some variables/labels are renamed to avoid further
confusion in future).
(3) The SMAP register offsets were all off-by-four, though by
fluke this didn't actually have any ill effects.
All these changes have been tested on real hardware (PB926
plus the PCI backplane), as well as on QEMU. I have confirmed
that IRQs and PCI PIO and MMIO work OK.
PCI bus-master DMA doesn't seem to work on h/w -- as far as I can
tell the device is correctly managing to DMA to the right places
in memory, but every other 32 bit word is corrupt (at least judging
from rtl8139 debug dumps of the frames it's receiving). I'm not
sure what's going on here, but since this is disjoint from
the irq and I/O issues I don't think that applying the
patches that fix those should be stalled on trying to debug
DMA problems. (DMA works fine on QEMU, incidentally.)

The SMAP register offsets in the versatile PCI controller code were
all off by four. (This didn't have any observable bad effects
because on this board PHYS_OFFSET is zero, and (a) writing zero to
the flags register at offset 0x10 has no effect and (b) the reset
value of the SMAP register is zero anyway, so failing to write SMAP2
didn't matter.)

The versatile PCI controller code was confused between the
PCI I/O window (at 0x43000000) and the first PCI memory
window (at 0x44000000). Pass the correct base address to
pci_remap_io() so that PCI I/O accesses work.
Since the first PCI memory window isn't used at all (it's
an odd size), rename the associated variables and labels
so that it's clear that it isn't related to the I/O window.
This has been tested and confirmed to fix PCI I/O accesses
both on physical PB926+PCI backplane hardware and on QEMU.

The PCI controller code for the Versatile board has never had the
correct IRQ mapping for hardware. For many years it had an odd
mapping ("all interrupts are int 27") which aligned with the
equivalent bug in QEMU. However as of commit 1bc39ac5da
the mapping changed and no longer matched either hardware or QEMU,
with the result that any PCI card beyond the first in QEMU would
not have functioning interrupts; for example a boot with a SCSI
controller would time out as follows:
------------
sym0: <895a> rev 0x0 at pci 0000:00:0d.0 irq 92
sym0: SCSI BUS has been reset.
scsi0 : sym-2.2.3
[...]
scsi 0:0:0:0: ABORT operation started
scsi 0:0:0:0: ABORT operation timed-out.
scsi 0:0:0:0: DEVICE RESET operation started
scsi 0:0:0:0: DEVICE RESET operation timed-out.
scsi 0:0:0:0: BUS RESET operation started
scsi 0:0:0:0: BUS RESET operation timed-out.
scsi 0:0:0:0: HOST RESET operation started
sym0: SCSI BUS has been reset
------------
Fix the mapping so that it matches real hardware (checked against the
schematics for PB926 and backplane, and tested against the hardware).
This allows PCI cards using interrupts to work on hardware for the
first time; this change will also work with QEMU 1.5 or later, where
the equivalent bugs in the modelling of the hardware have been fixed.
Although QEMU will attempt to autodetect whether the kernel is
expecting the long-standing "everything is int 27" mapping or the one
hardware has, for certainty we force it into "definitely behave like
hardware mode"; this will avoid unexpected surprises later if we
implement sparse irqs. This is harmless on hardware.
Thanks to Paul Gortmaker for bisecting the problem and finding an initial
solution, to Russell King for providing the correct interrupt mapping,
and to Guenter Roeck for providing an initial version of this patch
and prodding me into relocating the hardware and retesting everything.

Now that the PL01X debug include can mostly stand alone without

a lot of debug-macros include files.
The autodetect case for Versatile Express and the ux500 are left alone;

A large number of cleanups, all over the platforms. This is dominated
largely by the Samsung platforms (s3c, s5p, exynos) and a few of the
others moving code out of arch/arm into more appropriate subsystems.
The clocksource and irqchip drivers are now abstracted to the point
where platforms that are already cleaned up do not need to even specify
the driver they use, it can all get configured from the device tree
as we do for normal device drivers. The clocksource changes basically
touch every single platform in the process.
We further clean up the use of platform specific header files here,
with the goal of turning more of the platforms over to being
"multiplatform" enabled, which implies that they cannot expose
their headers to architecture independent code any more.
It is expected that no functional changes are part of the cleanup.
The overall reduction in total code lines is mostly the result of
removing broken and obsolete code.

The PCI IRQs were regressing due to two things:
- The PCI glue layer was using an hard-coded IRQ 27 offset.
This caused the immediate regression.
- The SIC IRQ mask was inverted (i.e. a bit was indeed set to
one for each valid IRQ on the SIC, but accidentally inverted
in the init call). This has been around forever, but we have
been saved by some other forgiving code that would reserve
IRQ descriptors in this range, as the versatile is
non-sparse.
When the IRQs were bumped up 32 steps so as to avoid using IRQ
zero and avoid touching the 16 legacy IRQs, things broke.
Introduce an explicit valid mask for the IRQs that are active
on the PIC/SIC, and pass that. Use the BIT() macro from
<linux/bitops.h> to make sure we hit the right bits, readily
defined in <mach/platform.h>.

Merge tag 'gic-vic-to-irqchip' of git://sources.calxeda.com/kernel/linux into next/cleanup
From Rob Herring:
Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas
Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
and adapted to use the new infrastructure. All DT enabled platforms
using GIC and VIC are converted over to use the new irqchip_init.
* tag 'gic-vic-to-irqchip' of git://sources.calxeda.com/kernel/linux:
irqchip: Move ARM vic.h to include/linux/irqchip/arm-vic.h
ARM: picoxcell: use common irqchip_init function
ARM: spear: use common irqchip_init function
irqchip: Move ARM VIC to drivers/irqchip
ARM: samsung: remove unused tick.h
ARM: remove unneeded vic.h includes
ARM: remove mach .handle_irq for VIC users
ARM: VIC: set handle_arch_irq in VIC initialization
ARM: VIC: shrink down vic.h
irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h
ARM: use common irqchip_init for GIC init
irqchip: Move ARM GIC to drivers/irqchip
ARM: remove mach .handle_irq for GIC users
ARM: GIC: set handle_arch_irq in GIC initialization
ARM: GIC: remove direct use of gic_raise_softirq
ARM: GIC: remove assembly ifdefs from gic.h
ARM: mach-ux500: use SGI0 to wake up the other core
arm: add set_handle_irq() to register the parent IRQ controller handler function
irqchip: add basic infrastructure
irqchip: add to the directories part of the IRQ subsystem in MAINTAINERS
Fixed up massive merge conflicts with the timer cleanup due to adjacent changes:

Clockevent cleanup series from Shawn Guo.
Resolved move/change conflict in mach-pxa/time.c due to the sys_timer
cleanup.
* clocksource/cleanup:
clocksource: use clockevents_config_and_register() where possible
ARM: use clockevents_config_and_register() where possible
clockevents: export clockevents_config_and_register for module use
+ sync to Linux 3.8-rc3

Now that we have VIC moved to drivers/irqchip and all VIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

Now that the VIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static. Move vic_handle_irq
to avoid a forward declaration.

With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

The Versatile starts to register Linux IRQ numbers from offset 0
which is illegal, since this is NO_IRQ. Bump all hard-coded IRQs
by 32 to get rid of the problem.
