[Why]
New GCC warnings for stringop-truncation and stringop-overflow help
catch common misuse of strncpy. This patch suppresses these warnings
by fixing bugs identified by them.
[How]
Since the parameter passed for name in amdpgu_dm_create_common_mode has
no fixed length, if the string is >= DRM_DISPLAY_MODE_LEN then
mode->name will not be null-terminated.
The truncation in fill_audio_info won't actually occur (and the string
will be null-terminated since the buffer is initialized to zero), but
the warning can be suppressed by using the proper buffer size.
This patch fixes both issues by using the real size for the buffer and
making use of strscpy (which always terminates).

SoCs that contain MDP5 have a top level wrapper called MDSS that
manages locks, power and irq for the sub-blocks within it.
Irq for HDMI is also routed through the MDSS.
Shortly after the Hot Plug Detection (HPD) is enabled in HDMI,
HDMI interrupts are recieved by the MDSS interrupt handler.
However at this moment the HDMI irq is still not mapped to
the MDSS irq domain so the HDMI irq handler cannot be called
to process the interrupts.
This leads to a flood of HDMI interrupts on CPU 0.
If we are lucky to have the HDMI initialization running on a
different CPU, it will eventually map the HDMI irq to MDSS irq
domain, the next HDMI interrupt will be handled by the HDMI irq
handler, the interrupt flood will stop and we will recover.
If the HDMI initialization is running on CPU 0, then it cannot
complete and there is nothing to stop the interrupt flood on
CPU 0. The system is stuck.
Fix this by moving the HPD enablement after the HDMI irq is
mapped to the MDSS irq domain.

The DSI encoder sets dssdev->ops->dsi.set_config, which is stored at the
same offset as dssdev->ops->hdmi.set_hdmi_mode. The code in omap_encoder
only checks if dssdev->ops->hdmi.set_hdmi_mode is NULL. Due to the way
union works, it won't be NULL if dsi.set_config is set. This means
dsi_set_config will be called with config=hdmi_mode=false=NULL parameter
resulting in a NULL dereference. Also the dereference happens while
console is locked, so kernel hangs without any debug output without
"fb.lockless_register_fb=1" parameter.
This restructures the code, so that the HDMI mode is only configured
for HDMI output types.

panel-dpi used to convey the bus-flags via the videomode, but recent
changes changed the use of videomode to DRM's drm_display_mode which
does not contain bus-flags. This broke panel-dpi, which didn't
explicitly store the bus-flags into dssdev->bus_flags.
Fix this by setting dssdev->bus_flags. Also change the bus_flags type to
u32, as that is the type used in the DRM framework, and we would get a
warning with drm_bus_flags_from_videomode() otherwise.

Major stability-related one is the removal of a regulator from DT on

Merge tag 'pci-v4.20-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
- Fix a link speed checking interface that broke PCIe gen3 cards in
gen1 slots (Mikulas Patocka)
- Fix an imx6 link training error (Trent Piepho)
- Fix a layerscape outbound window accessor calling error (Hou
Zhiqiang)
- Fix a DesignWare endpoint MSI-X address calculation error (Gustavo
Pimentel)
* tag 'pci-v4.20-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
PCI: Fix incorrect value returned from pcie_get_speed_cap()
PCI: dwc: Fix MSI-X EP framework address calculation bug
PCI: layerscape: Fix wrong invocation of outbound window disable accessor
PCI: imx6: Fix link training status detection in link up check
The macros PCI_EXP_LNKCAP_SLS_*GB are values, not bit masks. We must mask
the register and compare it against them.
This fixes errors like this:
amdgpu: [powerplay] failed to send message 261 ret is 0
when a PCIe-v3 card is plugged into a PCIe-v1 slot, because the slot is
being incorrectly reported as PCIe-v3 capable.
6cf57be0f7, which appeared in v4.17, added pcie_get_speed_cap() with the
incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask. 5d9a633040, which
appeared in v4.19, changed amdgpu to use pcie_get_speed_cap(), so the
amdgpu bug reports below are regressions in v4.19.
Fixes: 6cf57be0f7 ("PCI: Add pcie_get_speed_cap() to find max supported link speed")
Fixes: 5d9a633040 ("drm/amdgpu: use pcie functions for link width and speed")

[bhelgaas: update comment, remove use of PCI_EXP_LNKCAP_SLS_8_0GB and
PCI_EXP_LNKCAP_SLS_16_0GB since those should be covered by PCI_EXP_LNKCAP2,
remove test of PCI_EXP_LNKCAP for zero, since that register is required]

Merge tag 'fscache-fixes-20181130' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull fscache and cachefiles fixes from David Howells:
"Misc fixes:
- Fix an assertion failure at fs/cachefiles/xattr.c:138 caused by a
race between a cache object lookup failing and someone attempting
to reenable that object, thereby triggering an update of the
object's attributes.
- Fix an assertion failure at fs/fscache/operation.c:449 caused by a
split atomic subtract and atomic read that allows a race to happen.
- Fix a leak of backing pages when simultaneously reading the same
page from the same object from two or more threads.
- Fix a hang due to a race between a cache object being discarded and
the corresponding cookie being reenabled.
There are also some minor cleanups:
- Cast an enum value to a different enum type to prevent clang from
generating a warning. This shouldn't cause any sort of change in
the emitted code.
- Use ktime_get_real_seconds() instead of get_seconds(). This is just
used to uniquify a filename for an object to be placed in the
graveyard. Objects placed there are deleted by cachfilesd in
userspace immediately thereafter.
- Remove an initialised, but otherwise unused variable. This should
have been entirely optimised away anyway"

The linux-mips.org infrastructure has been unreliable recently & nobody
with sufficient access to fix it is around to do so. As a result we're
moving away from it, and part of this is migrating our mailing list to
kernel.org.
Replace all instances of linux-mips@linux-mips.org in MAINTAINERS with
the shiny new linux-mips@vger.kernel.org address.
The new list is now being archived on kernel.org at
https://lore.kernel.org/linux-mips/ which also holds the history of the
old linux-mips.org list.

ocfs2_get_dentry() calls iput(inode) to drop the reference count of
inode, and if the reference count hits 0, inode is freed. However, in
this function, it then reads inode->i_generation, which may result in a
use after free bug. Move the put operation later.
