drm/vc4: add gem_info node via debugfs
The memps requires gem_info with gem_names to analyze graphics
shared memory, so this patch adds gem_info node via debugfs

Let's save pid/tgid in private file data only once when gem object is
created or prime_fd is imported and use them on gem_info. This is to
solve the wrong pid problem of gem_info created as different processes

of: overlay: set node fields from properties when add new overlay node
commit
f96278810150fc39085d1872e5b39ea06366d03e upstream.
Overlay nodes added by add_changeset_node() do not have the node
fields name, phandle, and type set.
The node passed to __of_attach_node() when the add node changeset
entry is processed does not contain any properties. The node's
properties are located in add property changeset entries that will
be processed after the add node changeset is applied.
Set the node's fields in the node contained in the add node
changeset entry and do not set them to incorrect values in
add_changeset_node().
A visible symptom that is fixed by this patch is the names of nodes
added by overlays that have an entry in /sys/bus/platform/drivers/*/
will contain the unit-address but the node-name will be <NULL>, for
example, "
fc4ab000.<NULL>". After applying the patch the name, in
this example, for node restart@
fc4ab000 is "
fc4ab000.restart".

If the properties are already in the live tree then there is no

x86/ftrace: Do not call function graph from dynamic trampolines
[ Upstream commit
d2a68c4effd821f0871d20368f76b609349c8a3b ]
Since commit
79922b8009c07 ("ftrace: Optimize function graph to be
called directly"), dynamic trampolines should not be calling the
function graph tracer at the end. If they do, it could cause the function
graph tracer to trace functions that it filtered out.
Right now it does not cause a problem because there's a test to check if
the function graph tracer is attached to the same function as the
function tracer, which for now is true. But the function graph tracer is
undergoing changes that can make this no longer true which will cause
the function graph tracer to trace other functions.
For example:
# cd /sys/kernel/tracing/
# echo do_IRQ > set_ftrace_filter
# mkdir instances/foo
# echo ip_rcv > instances/foo/set_ftrace_filter
# echo function_graph > current_tracer
# echo function > instances/foo/current_tracer
Would cause the function graph tracer to trace both do_IRQ and ip_rcv,
if the current tests change.
As the current tests prevent this from being a problem, this code does
not need to be backported. But it does make the code cleaner.

binder: fix race between munmap() and direct reclaim
commit
5cec2d2e5839f9c0fec319c523a911e0a7fd299f upstream.
An munmap() on a binder device causes binder_vma_close() to be called
which clears the alloc->vma pointer.
If direct reclaim causes binder_alloc_free_page() to be called, there
is a race where alloc->vma is read into a local vma pointer and then
used later after the mm->mmap_sem is acquired. This can result in
calling zap_page_range() with an invalid vma which manifests as a
use-after-free in zap_page_range().
The fix is to check alloc->vma after acquiring the mmap_sem (which we
were acquiring anyway) and skip zap_page_range() if it has changed
to NULL.

include/linux/module.h: copy __init/__exit attrs to init/cleanup_module
commit
a6e60d84989fa0e91db7f236eda40453b0e44afa upstream.
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.
In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.
These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.
Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias.
In order to keep the warning enabled, we decided to silence
this case. Ideally, we would mark the aliases directly
as __init/__exit. However, there are currently around 132 modules
in the kernel which are missing __init/__exit in their init/cleanup
functions (either because they are missing, or for other reasons,
e.g. the functions being called from somewhere else); and
a section mismatch is a hard error.
A conservative alternative was to mark the aliases as __cold only.
However, since we would like to eventually enforce __init/__exit
to be always marked, we chose to use the new __copy function
attribute (introduced by GCC 9 as well to deal with this).
With it, we copy the attributes used by the target functions
into the aliases. This way, functions that were not marked
as __init/__exit won't have their aliases marked either,
and therefore there won't be a section mismatch.
Note that the warning would go away marking either the extern
declaration, the definition, or both. However, we only mark
the definition of the alias, since we do not want callers
(which only see the declaration) to be compiled as if the function
was __cold (and therefore the paths leading to those calls
would be assumed to be unlikely).

Compiler Attributes: add support for __copy (gcc >= 9)
commit
c0d9782f5b6d7157635ae2fd782a4b27d55a6013 upstream.
From the GCC manual:
copy
copy(function)
The copy attribute applies the set of attributes with which function
has been declared to the declaration of the function to which
the attribute is applied. The attribute is designed for libraries
that define aliases or function resolvers that are expected
to specify the same set of attributes as their targets. The copy
attribute can be used with functions, variables, or types. However,
the kind of symbol to which the attribute is applied (either
function or variable) must match the kind of symbol to which
the argument refers. The copy attribute copies only syntactic and
semantic attributes but not attributes that affect a symbol’s
linkage or visibility such as alias, visibility, or weak.
The deprecated attribute is also not copied.
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html
The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target, e.g.:
void __cold f(void) {}
void __alias("f") g(void);
diagnoses:
warning: 'g' specifies less restrictive attribute than
its target 'f': 'cold' [-Wmissing-attributes]
Using __copy(f) we can copy the __cold attribute from f to g:
void __cold f(void) {}
void __copy(f) __alias("f") g(void);
This attribute is most useful to deal with situations where an alias
is declared but we don't know the exact attributes the target has.
For instance, in the kernel, the widely used module_init/exit macros
define the init/cleanup_module aliases, but those cannot be marked
always as __init/__exit since some modules do not have their
functions marked as such.

maybe not even the primary one), hence we need to check for the

We had a more radical approach before in commit

but that resulted in new warnings and oopses on shutdown on rk3399
chromeos devices.
So second try is resurrecting Vicentes shutdown change which should
achieve the same result but in a less drastic way.

drm/tegra: gem: Fix CPU-cache maintenance for BO's allocated using get_pages()
commit
61b51fb51c01a519a249d28ec55c6513a13be5a3 upstream.
The allocated pages need to be invalidated in CPU caches. On ARM32 the
DMA_BIDIRECTIONAL flag only ensures that data is written-back to DRAM and
the data stays in CPU cache lines. While the DMA_FROM_DEVICE flag ensures
that the corresponding CPU cache lines are getting invalidated and nothing
more, that's exactly what is needed for a newly allocated pages.
This fixes randomly failing rendercheck tests on Tegra30 using the
Opentegra driver for tests that use small-sized pixmaps (10x10 and less,
i.e. 1-2 memory pages) because apparently CPU reads out stale data from
caches and/or that data is getting evicted to DRAM at the time of HW job
execution.
