[ Upstream commit 8b9433eb4de3c26a9226c981c283f9f4896ae030 ]

On a DIO_SKIP_HOLES filesystem, the ->get_block() method is currently
not allowed to create blocks for an empty inode.  This confusion comes
from trying to bit shift a negative number, so check the size of the
inode first.

The problem is most visible for hfsplus, because the fallback to
buffered I/O doesn't happen and the write fails with EIO.  This is in
part the fault of the module, because it gives a wrong return value on
->get_block(); that will be fixed in a separate patch.

Often userspace doesn't know when the kernel will be calling dma_buf_detach
on the buffer.
If userpace starts its CPU access at the same time as the sg list is being
freed it could end up accessing the sg list after it has been freed.

Although TMDS clock is required for HDMI to properly function,
nobody called clk_prepare_enable(). This fixes reference counting
issues and makes sure clock is running when it needs to be running.

Due to TDMS clock being parent clock for DDC clock, TDMS clock
was turned on/off for each EDID probe, causing spurious failures
for certain HDMI/DVI screens.

[ Upstream commit a0dc02039a2ee54fb4ae400e0b755ed30e73e58c ]

In ieee80211_rx_h_mesh_fwding, we increment the 'dropped_frames_ttl'
counter when we decrement the ttl to zero.  For unicast frames
destined for other hosts, we stop processing the frame at that point.

For multicast frames, we do not rebroadcast it in this case, but we
do pass the frame up the stack to process it on this STA.  That
doesn't match the usual definition of "dropped," so don't count
those as such.

With this change, something like `ping6 -i0.2 ff02::1%mesh0` from a
peer in a ttl=1 network no longer increments the counter rapidly.

[ Upstream commit 97715058b70da1262fd07798c8b2e3e894f759dd ]

When CONFIG_NO_AUTO_INLINE was present in linux-next (which added
'-fno-inline-functions' to KBUILD_CFLAGS), an allyesconfig build with
Clang failed at the modpost stage:

ERROR: "is_broadcast_mac_addr" [drivers/staging/rtl8723bs/r8723bs.ko] undefined!
ERROR: "is_zero_mac_addr" [drivers/staging/rtl8723bs/r8723bs.ko] undefined!
ERROR: "is_multicast_mac_addr" [drivers/staging/rtl8723bs/r8723bs.ko] undefined!

These functions were marked as extern inline, meaning that if inlining
doesn't happen, the function will be undefined, as it is above.

This happens to work with GCC because the '-fno-inline-functions' option
respects the __inline attribute so all instances of these functions are
inlined as expected and the definition doesn't actually matter. However,
with Clang and '-fno-inline-functions', a function has to be marked with
the __always_inline attribute to be considered for inlining, which none
of these functions are. Clang tries to find the symbol definition
elsewhere as it was told and fails, which trickles down to modpost.

To make sure that this code compiles regardless of compiler and make the
intention of the code clearer, use 'static' to ensure these functions
are always defined, regardless of inlining. Additionally, silence a
checkpatch warning by switching from '__inline' to 'inline'.

Changes since V1:
* Use dev_info instead of printk
* Use dev_warn instead of BUG_ON

Previously, sysfs_create_group was called before all initialization had
fully run - specifically, before pci_set_drvdata was called. Since the
sysctl group is visible to userspace as soon as sysfs_create_group
returns, a small window of time existed during which a process could read
from an uninitialized/partially-initialized device.

This commit moves the creation of the sysctl group to after all
initialized is completed. This ensures that it's impossible for
userspace to read from a sysctl file before initialization has fully
completed.

To catch any future regressions, I've added a check to ensure
that proc_thermal_emum_mode is never PROC_THERMAL_NONE when a process
tries to read from a sysctl file. Previously, the aforementioned race
condition could result in the 'else' branch
running while PROC_THERMAL_NONE was set,
leading to a null pointer deference.

The motivation for this change was lockdep splat like below.

| potentially unexpected fatal signal 11.
| BUG: sleeping function called from invalid context at ../mm/page_alloc.c:4317
| in_atomic(): 1, irqs_disabled(): 0, pid: 57, name: segv

| Preemption disabled at:

|  do_signal+0x30/0x224
|  resume_user_mode_begin+0x90/0xd8

So signal handling core calls show_regs() with preemption disabled but
an ensuing GFP_KERNEL page allocator call is flagged by lockdep.

We could have switched to GFP_NOWAIT, but turns out that is not enough
anways and eliding page allocator call leads to less code and
instruction traces to sift thru when debugging pesky crashes.

FWIW, this patch doesn't cure the lockdep splat (which next patch does).

It's GNU Make and linker specific.

The default Makefile rule looks like:

$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)

When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.

More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

https://lkml.org/lkml/2010/2/10/362

tools/perf: libraries must come after objects

Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libpthread.

[ Upstream commit 827cb0323928952c0db9515aba9d534fb1285b3f ]

I submitted this driver several times before it got accepted. The
first series hasn't been accepted but the DTS binding did made it.
I then made a second series that added generic reset support to the
PHY core, this in turn required a change to the DT binding. This
second series seemed to have been ignored, so I did a third one
without the change to the PHY core and the DT binding update, and this
last attempt finally made it.

But two months later the DT binding update from the second series has
been integrated too. So now the driver doesn't match the binding and
the only DTS using it. This patch fix the driver to match the new
binding.

Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.

1) Uses of size += snprintf(buf, SIZE - size, fmt, ...)
In this case, if snprintf would have written more characters than what the
buffer size (SIZE) is, then size will end up larger than SIZE. In later
uses of snprintf, SIZE - size will result in a negative number, leading
to problems. Note that size might already be too large by using
size = snprintf before the code reaches a case of size += snprintf.

2) If size is ultimately used as a length parameter for a copy back to user
space, then it will potentially allow for a buffer overflow and information
disclosure when size is greater than SIZE. When the size is used to index
the buffer directly, we can have memory corruption. This also means when
size = snprintf... is used, it may also cause problems since size may become
large.  Copying to userspace is mitigated by the HARDENED_USERCOPY kernel
configuration.

The solution to these issues is to use scnprintf which returns the number of
characters actually written to the buffer, so the size variable will never
exceed SIZE.

Using sizeof(pointer) for determining the size of a memset() only works
when the size of the pointer and the size of type to which it points are
the same. For pte_t this is only true for 64bit and 32bit-NONPAE. On 32bit
PAE systems this is wrong as the pointer size is 4 byte but the PTE entry
is 8 bytes. It's actually not a real world issue as this code depends on
64bit, but it's wrong nevertheless.

Use sizeof(*p) for correctness sake.

				       prtd->periods);

In this code prtd->pcm_size is the buffer_size and prtd->periods comes
from params->buffer.fragments.  If we allow the number of fragments to
be zero then it results in a divide by zero bug.  One possible fix would
be to use prtd->pcm_count directly instead of using the division to
re-calculate it.  But I decided that it doesn't really make sense to
allow zero fragments.

The sysfs phy_identifier attribute for a sas_end_device comes from the rphy
phy_identifier value.

Currently this is not being set for rphys with an end device attached, so
we see incorrect symlinks from systemd disk/by-path:

Indeed, each sas_end_device phy_identifier value is 0:

root@localhost:/# more sys/class/sas_device/end_device-0\:0\:2/phy_identifier
0
root@localhost:/# more sys/class/sas_device/end_device-0\:0\:10/phy_identifier
0

This patch fixes the discovery code to set the phy_identifier.  With this,
we now get proper symlinks:

root@localhost:~# ls -l /dev/disk/by-path/
total 0
lrwxrwxrwx 1 root root  9 Feb 13 11:53 platform-HISI0162:01-sas-exp0x500e004aaaaaaa1f-phy10-lun-0 -> ../../sdg
