Another round of SPDX header file fixes for 5.2-rc4
These are all more "GPL-2.0-or-later" or "GPL-2.0-only" tags being
added, based on the text in the files. We are slowly chipping away at
the 700+ different ways people tried to write the license text. All of
these were reviewed on the spdx mailing list by a number of different
people.
We now have over 60% of the kernel files covered with SPDX tags:
$ ./scripts/spdxcheck.py -v 2>&1 | grep Files
Files checked: 64533
Files with SPDX: 40392
Files with errors: 0
I think the majority of the "easy" fixups are now done, it's now the
start of the longer-tail of crazy variants to wade through.

Here are some small char and misc driver fixes for 5.2-rc4 to resolve a
number of reported issues.
The most "notable" one here is the kernel headers in proc^Wsysfs fixes.
Those changes move the header file info into sysfs and fixes the build
issues that you reported.
Other than that, a bunch of small habanalabs driver fixes, some fpga
driver fixes, and a few other tiny driver fixes.
All of these have been in linux-next for a while with no reported
issues.

The trace buffer address is 40 bits wide.
The end of the buffer is set in the RWP register (lower 32 bits), and in
the RWPHI register (upper 8 bits).
Currently only the lower 32 bits are read, and this patch fixes it and
concatenates the upper 8 bits to the output address.

The debugfs interface for accessing DRAM virtual addresses currently
uses the 12 LSBs of a virtual address as an offset.
However, it should use the 20 LSBs in case the device MMU page size is
2MB instead of 4KB.
This patch fixes the offset calculation to be based on the page size.

This patch fix a bug in the mmu code that checks whether we can use huge
page mappings for host pages.
The code is supposed to enable huge page mappings only if ALL DMA
addresses are aligned to 2MB AND the number of pages in each DMA chunk is
a modulo of the number of pages in 2MB. However, the code ignored the
first requirement for the first DMA chunk.
This patch fix that issue by making sure the requirement of address
alignment is validated against all DMA chunks.

This tag contains the following fixes:
- Halt debug engines when user process closes the FD. We can't allow the
device to issue transactions for a user which doesn't exists anymore.
- Fix various security holes in debugfs API.
- Add a new opcode to the DEBUG IOCTL API. The opcode is designed
for setting the device into and out of debug mode. Although not a fix
per-se, because this is a new IOCTL which is upstreamed in kernel 5.2, I
think this is justified at this point because we won't be able to change
the API later.
- Fix a bug where the code used an uninitialized mutex

habanalabs: Avoid using a non-initialized MMU cache mutex
habanalabs: fix debugfs code
uapi/habanalabs: add opcode for enable/disable device debug mode
habanalabs: halt debug engines on user process close
The MMU cache mutex is used in the ASIC hw_init() functions, but it is
initialized only later in hl_mmu_init().
This patch prevents it by moving the initialization to the
device_early_init() function.

This fixes multiple things in the habanalabs debugfs code, in particular:
- mmu_write() was unnecessarily verbose, copying around between multiple
buffers
- mmu_write() could write a user-specified, unbounded amount of userspace
memory into a kernel buffer (out-of-bounds write)
- multiple debugfs read handlers ignored the user-supplied count,
potentially corrupting out-of-bounds userspace data
- hl_device_read() was unnecessarily verbose
- hl_device_write() could read uninitialized stack memory
- multiple debugfs read handlers copied terminating null characters to
userspace

This patch fix a potential bug where a user's process has closed
unexpectedly without disabling the debug engines. In that case, the debug
engines might continue running but because the user's MMU mappings are
going away, we will get page fault errors.
This behavior is also opposed to the general rule where nothing runs on
the device after the user process closes.
The patch stops the debug H/W engines upon process termination and thus
makes sure nothing runs on the device after the process goes away.

There are a couple potential integer overflows here.
round_up(m->size + (m->addr & ~PAGE_MASK), PAGE_SIZE);
The first thing is that the "m->size + (...)" addition could overflow,
and the second is that round_up() overflows to zero if the result is
within PAGE_SIZE of the type max.
In this code, the "m->size" variable is an u64 but we're saving the
result in "map_size" which is an unsigned long and genwqe_user_vmap()
takes an unsigned long as well. So I have used ULONG_MAX as the upper
bound. From a practical perspective unsigned long is fine/better than
trying to change all the types to u64.

To facilitate additional options to get_user_pages_fast() change the
singular write parameter to be gup_flags.
This patch does not change any functionality. New functionality will
follow in subsequent patches.
Some of the get_user_pages_fast() call sites were unchanged because they
already passed FOLL_WRITE or 0 for the write parameter.
NOTE: It was suggested to change the ordering of the get_user_pages_fast()
arguments to ensure that callers were converted. This breaks the current
GUP call site convention of having the returned pages be the final
parameter. So the suggestion was rejected.

SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents the kernel
from accidentally accessing userspace outside copy_to/from_user(), or
ever executing userspace.
- KASAN support on 32-bit.
- Rework of where we map the kernel, vmalloc, etc. on 64-bit hash to use the
same address ranges we use with the Radix MMU.
- A rewrite into C of large parts of our idle handling code for 64-bit Book3S
(ie. power8 & power9).
- A fast path entry for syscalls on 32-bit CPUs, for a 12-17% speedup in the
null_syscall benchmark.
- On 64-bit bare metal we have support for recovering from errors with the time
base (our clocksource), however if that fails currently we hang in __delay()
and never crash. We now have support for detecting that case and short
circuiting __delay() so we at least panic() and reboot.
- Add support for optionally enabling the DAWR on Power9, which had to be
disabled by default due to a hardware erratum. This has the effect of
enabling hardware breakpoints for GDB, the downside is a badly behaved
program could crash the machine by pointing the DAWR at cache inhibited
memory. This is opt-in obviously.
- xmon, our crash handler, gets support for a read only mode where operations
that could change memory or otherwise disturb the system are disabled.
Plus many clean-ups, reworks and minor fixes etc.

Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small driver
subsystems" these days. Which is fine with me, if it makes things
easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues.

Pull char/misc update part 2 from Greg KH:
"Here is the "real" big set of char/misc driver patches for 5.2-rc1
Loads of different driver subsystem stuff in here, all over the places:
- thunderbolt driver updates
- habanalabs driver updates
- nvmem driver updates
- extcon driver updates
- intel_th driver updates
- mei driver updates
- coresight driver updates
- soundwire driver cleanups and updates
- fastrpc driver updates
- other minor driver updates
- chardev minor fixups
Feels like this tree is getting to be a dumping ground of "small
driver subsystems" these days. Which is fine with me, if it makes
things easier for those subsystem maintainers.
All of these have been in linux-next for a while with no reported
issues"

This is the first pull request for the char/misc driver tree for 5.2-rc1
This contains only a small number of bugfixes that would have gone to
you for 5.1-rc8 if that had happened, but instead I let them sit in
linux-next for an extra week just "to be sure".
The "big" patch here is for hyper-v, fixing a bug in their sysfs files
that could cause big problems. The others are all small fixes,
resolving reported issues that showed up in 5.1-rcs, plus some odd
'static' cleanups for the phy drivers that really should have waited for
-rc1. Most of these are tagged for the stable trees, so 5.1 will pick
them up.
All of these have been in linux-next for a while, with no reported
issues.

"Remove Mysterious Macro Intended to Obscure Weird Behaviours (mmiowb())
Remove mmiowb() from the kernel memory barrier API and instead, for

The only relatively recent changes have been addressing review
comments on the documentation, which is in a much better shape thanks
to the efforts of Ben and Ingo.
I was initially planning to split this into two pull requests so that
you could run the coccinelle script yourself, however it's been plain
sailing in linux-next so I've just included the whole lot here to keep
things simple"

atmel_tclib is probed too late in the boot process to be able to use the
TCB as the boot clocksource. This is an issue for SoCs without the PIT
(sams70, samv70 and samv71 families) as they simply currently can't boot.
Get rid of the atmel_tclib dependency and probe everything on our own using
the correct device tree binding.
This also allows getting rid of ATMEL_TCB_CLKSRC_BLOCK and makes the driver
a bit more flexible as the TCB is not hardcoded in the kernel anymore.

Event_fd is only used in the driver frontend, so it does not
need to exist in the backend code. Relocate it to the frontend
and provide an opaque mechanism for consumers instead.
