When device is removed, we need to make sure the F/W won't send us
any more events because during the remove process we disable the
interrupts.

Driver does not zero some pci counters packets before sending

When using Deep learning framework such as tensorflow or pytorch, there
are tens of thousands of host memory mappings. When the user frees
all those mappings at the same time, the process of unmapping and
unpinning them can take a long time, which may cause a soft lockup
bug.
To prevent this, we need to free the core to do other things during
the unmapping process. For now, we chose to do it every 32K unmappings
(each unmap is a single 4K page).

There are some points in the reset process where if the code fails
for some reason, and the system admin tries to initiate the reset
process again we will get a kernel panic.
This is because there aren't any protections in different fini
functions that are called during the reset process.
The protections that are added in this patch make sure that if the fini
functions are called multiple times, without calling init functions
between them, there won't be double release of already released
resources.

When doing dma_alloc_coherent in the driver, we add a certain hard-coded
offset to the DMA address before returning to the callee function. This
offset is needed when our device use this DMA address to perform
outbound transactions to the host.
However, if we want to map the DMA'able memory to the user via
dma_mmap_coherent(), we need to pass the original dma address, without
this offset. Otherwise, we will get erronouos mapping.

Inconveniently devm_ioport_map() and devm_ioremap_resource()
return errors differently, i.e. former uses simply NULL pointer,
while the latter an error pointer.
Due to this, we have to check each of them separately.

We need to make sure our device is idle when rebooting a virtual

Up until now validation errors were counted in the parsing field
of the cs_counters struct, so we added a new counter and increased
it when needed.
In addition, there were some locations where only one of the counters
was updated (ctx or aggregate) so add the second one to be updated
as well.

When the firmware security is enabled, the pcie_aux_dbi_reg_addr
register in the PCI controller is blocked. Therefore, ignore
the result of writing to this register and assume it worked. Also
remove the prints on errors in the internal ELBI write function.
If the security is enabled, the firmware is responsible for setting
this register correctly so we won't have any problem.
If the security is disabled, the write will work (unless something
is totally broken at the PCI level and then the whole sequence
will fail).
In addition, remove a write to register pcie_aux_dbi_reg_addr+4,
which was never actually needed.
Moreover, PCIE_DBI registers are blocked to access from host when
firmware security is enabled. Use a different register to flush the
writes.

In case the clock gating was enabled in preboot we need to disable it
at the H/W initialization stage before touching the MME/TPC registers.
Otherwise, the ASIC can get stuck. If the security is enabled in
the firmware level, the CGM is always disabled and the driver can't
enable it.

__builtin_object_size(x, 0) case. This test is called FORTIFY_OBJECT.
- runtime detection of the overrun of a char array within a structure.
This covers the __builtin_object_size(x, 1) case which can be used
for some string functions. This test is called FORTIFY_SUBOBJECT.

entry_SYSCALL_64_after_hwframe+0x44/0xa9
The reason is that rodata.o generates a dummy function that lives in
.rodata to validate that .rodata can't be executed; however, Clang 11 adds
KASAN globals support by generating module constructors to initialize
globals redzones. When Clang 11 adds a module constructor to rodata.o, it
is also added to .rodata: any attempt to call it on initialization results
in the above error.
Therefore, disable KASAN instrumentation for rodata.o.

There is no use for OF headers in the driver, but mod_devicetable.h
must be included. Update driver accordingly.

There is nothing special in the driver that requires to have
a special ACPI driver for it. Combine both into simple

We return 'err' in the error branch, but this variable may be set as
zero before. Fix it by setting 'err' as a negative value before we
goto the error label.

vmci_ctx_get_chkpt_doorbells()
A kernel-infoleak was reported by syzbot, which was caused because
dbells was left uninitialized.
Using kzalloc() instead of kmalloc() fixes this issue.

The usage of in_interrupt() in xpc_partition_disengaged() is clearly
intended to avoid canceling the timeout timer when the function is invoked
from the timer callback.
While in_interrupt() is deprecated and ill defined as it does not provide
what the name suggests it catches the intended case.
Add an argument to xpc_partition_disengaged() which is true if called
from timer and otherwise false.
Use del_timer_sync() instead of del_singleshot_timer_sync() which is the
same thing.
Note: This does not prevent reentrancy into the function as the function
has no concurrency control and timer callback and regular task context
callers can happen concurrently on different CPUs or the timer can
interrupt the task context before it is able to cancel it.
While the only driver which is providing the arch_xpc_ops callbacks
(xpc_uv) seems not to have a reentrancy problem and the only negative
effect would be a double dev_info() entry in dmesg, the whole mechanism is
conceptually broken.
But that's not subject of this cleanup endeavour and left as an exercise to
the folks who might have interest to make that code fully correct.
[bigeasy: Add the argument, use del_timer_sync().]

When building with KASAN and LKDTM, clang may implictly generate an
asan.module_ctor function in the LKDTM rodata object. The Makefile moves
the lkdtm_rodata_do_nothing() function into .rodata by renaming the
file's .text section to .rodata, and consequently also moves the ctor
function into .rodata, leading to a boot time crash (splat below) when
the ctor is invoked by do_ctors().
Let's prevent this by marking the function as noinstr rather than
notrace, and renaming the file's .noinstr.text to .rodata. Marking the
function as noinstr will prevent tracing and kprobes, and will inhibit
any undesireable compiler instrumentation.
The ctor function (if any) will be placed in .text and will work
correctly.
