Since segment_pages is no longer a compile time constant, it looks the
DIV_ROUND_UP(node->size, segment_pages) breaks the 32b build. Simplest
is just to use the ULL variant, but really we should need not need more
than u32 for the page alignment (also we are limited by that due to the
sg->length type), so also make it all u32.

Currently the jitter mechanism will require two timer ticks per
iteration, and it requires N iterations per bit. This N is determined
with a small measurement, and if it's too big, it won't waste time with
jitter entropy because it'd take too long or not have sufficient entropy
anyway.
With the current max N of 32, there are large timeouts on systems with a
small CONFIG_HZ. Rather than set that maximum to 32, instead choose a
factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for
different configurations of CONFIG_HZ.

Current stmmac driver will prepare/enable ptp_ref clock in
stmmac_init_tstamp_counter().
The stmmac_pltfr_noirq_suspend will disable it once in suspend flow.
But in resume flow,
stmmac_pltfr_noirq_resume --> stmmac_init_tstamp_counter
stmmac_resume --> stmmac_hw_setup --> stmmac_init_ptp --> stmmac_init_tstamp_counter
ptp_ref clock reference counter increases twice, which leads to unbalance
ptp clock when resume back.
Move ptp_ref clock prepare/enable out of stmmac_init_tstamp_counter to fix it.

If netif is running when stmmac_dvr_remove is invoked,
the unregister_netdev will call ndo_stop(stmmac_release) and
vlan_kill_rx_filter(stmmac_vlan_rx_kill_vid).
Currently, stmmac_dvr_remove() will disable pm runtime before
unregister_netdev. When stmmac_vlan_rx_kill_vid is invoked,
pm_runtime_resume_and_get in it returns EACCESS error number,
and reports:

"Including fixes from netfilter, bpf and wireless.
Still no major regressions, the release continues to be calm. An

There has been a few driver fixes (particularly a few fixes for false

Commit 3a0cf7ab8df3 ("ACPI: video: Change how we determine if brightness
key-presses are handled") made acpi_video_handles_brightness_key_presses()
report false when none of the ACPI Video Devices support backlight control.
But it turns out that at least on a Dell Inspiron N4010 there is no ACPI
backlight control, yet brightness hotkeys are still reported through
the ACPI Video Bus; and since acpi_video_handles_brightness_key_presses()
now returns false, brightness keypresses are now reported twice.
To fix this rename the has_backlight flag to may_report_brightness_keys and
also set it the first time a brightness key press event is received.
Depending on the delivery of the other ACPI (WMI) event vs the ACPI Video
Bus event this means that the first brightness key press might still get
reported twice, but all further keypresses will be filtered as before.
Note that this relies on other drivers reporting brightness key events
calling acpi_video_handles_brightness_key_presses() when delivering
the events (rather then once during driver probe). This is already
required and documented in include/acpi/video.h:
/*
* Note: The value returned by acpi_video_handles_brightness_key_presses()
* may change over time and should not be cached.
*/

nfp_tun_write_neigh() function will configure a tunnel neighbour when
calling nfp_tun_neigh_event_handler() or nfp_flower_cmsg_process_one_rx()
(with no tunnel neighbour type) from firmware.
When configuring IP on physical port as a tunnel endpoint, no operation
will be performed after receiving the cmsg mentioned above.
Therefore, add a progress to configure tunnel neighbour in this case.
v2: Correct format of fixes tag.

xenvif_rx_next_skb() is expecting the rx queue not being empty, but
in case the loop in xenvif_rx_action() is doing multiple iterations,
the availability of another skb in the rx queue is not being checked.
This can lead to crashes:

The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has
not been building cleanly on powerpc and causes link errors due to
mixing hard- and soft-float object files:
powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float
powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o
[..]
and while patches are floating around, it's not exactly obvious what is
going on.
The problem bisects to commit 41b7a347bf14 ("powerpc: Book3S 64-bit
outline-only KASAN support") but that is probably more about changing
config variables than the fundamental cause.
Despite the bisection result, a more directly related commit seems to be
26f4712aedbd ("drm/amd/display: move FPU related code from dcn31 to
dml/dcn31 folder"). It's probably a combination of the two.
This has been going on since the merge window, without any final word.
So instead of blindly applying patches that may or may not be the right
thing, let's disable this for now.
As Michael Ellerman says:
"IIUIC this code was never enabled on ppc before, so disabling it seems
like a reasonable fix to get the build clean"
and once we have more actual feedback (and find any potential users) we
can always re-enable it with the patch that fixes the issues and
back-port as necessary.

The initially merged version of the igc driver code (via commit
146740f9abc4, "igc: Add support for PF") contained the following
IGC_REMOVED checks in the igc_rd32/wr32() MMIO accessors:
u32 igc_rd32(struct igc_hw *hw, u32 reg)
{
u8 __iomem *hw_addr = READ_ONCE(hw->hw_addr);
u32 value = 0;
if (IGC_REMOVED(hw_addr))
return ~value;
value = readl(&hw_addr[reg]);
/* reads should not return all F's */
if (!(~value) && (!reg || !(~readl(hw_addr))))
hw->hw_addr = NULL;
return value;
}
And:
#define wr32(reg, val) \
do { \
u8 __iomem *hw_addr = READ_ONCE((hw)->hw_addr); \
if (!IGC_REMOVED(hw_addr)) \
writel((val), &hw_addr[(reg)]); \
} while (0)
E.g. igb has similar checks in its MMIO accessors, and has a similar
macro E1000_REMOVED, which is implemented as follows:
#define E1000_REMOVED(h) unlikely(!(h))
These checks serve to detect and take note of an 0xffffffff MMIO read
return from the device, which can be caused by a PCIe link flap or some
other kind of PCI bus error, and to avoid performing MMIO reads and
writes from that point onwards.
However, the IGC_REMOVED macro was not originally implemented:
#ifndef IGC_REMOVED
#define IGC_REMOVED(a) (0)
#endif /* IGC_REMOVED */
This led to the IGC_REMOVED logic to be removed entirely in a
subsequent commit (commit 3c215fb18e70, "igc: remove IGC_REMOVED
function"), with the rationale that such checks matter only for
virtualization and that igc does not support virtualization -- but a
PCIe device can become detached even without virtualization being in
use, and without proper checks, a PCIe bus error affecting an igc
adapter will lead to various NULL pointer dereferences, as the first
access after the error will set hw->hw_addr to NULL, and subsequent
accesses will blindly dereference this now-NULL pointer.
This patch reinstates the IGC_REMOVED checks in igc_rd32/wr32(), and
implements IGC_REMOVED the way it is done for igb, by checking for the
unlikely() case of hw_addr being NULL. This change prevents the oopses
seen when a PCIe link flap occurs on an igc adapter.

On corporate (CSME) ADL systems, the Ethernet Controller may stop working
("HW unit hang") after exiting from the s0ix state. The reason is that
CSME misses the message sent by the host. Enabling the dynamic GPT clock
solves this problem. This clock is cleared upon HW initialization.

The issue exists when multipath is enabled and the namespace is
shared, but all the other controller checks at nvme_is_unique_nsid()
are false. The reason for this issue is that nvme_is_unique_nsid()
returns false when is called from nvme_mpath_alloc_disk() due to an
uninitialized value of head->shared. The patch fixes it by setting
head->shared before nvme_mpath_alloc_disk() is called.

When releasing a DMA coherent buffer, sometimes, I don't know in what

Currently, the data flow of the max/min linkrate in the driver is
* in pm8001_get_lrate_mode():
hardcoded value ==> struct sas_phy
* in pm8001_bytes_dmaed():
struct pm8001_phy ==> struct sas_phy
* in pm8001_phy_control():
libsas data ==> struct pm8001_phy
Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), and the fields
in struct pm8001_phy are not initialized, sysfs
`/sys/class/sas_phy/phy-*/maximum_linkrate` always shows `Unknown`.
To fix the issue, change the dataflow to the following:
* in pm8001_phy_init():
initial value ==> struct pm8001_phy
* in pm8001_get_lrate_mode():
struct pm8001_phy ==> struct sas_phy
* in pm8001_phy_control():
libsas data ==> struct pm8001_phy
For negotiated linkrate, the current dataflow is:
* in pm8001_get_lrate_mode():
iomb data ==> struct asd_sas_phy ==> struct sas_phy
* in pm8001_bytes_dmaed():
struct asd_sas_phy ==> struct sas_phy
Since pm8001_bytes_dmaed() follows pm8001_get_lrate_mode(), the assignment
statements in pm8001_bytes_dmaed() are unnecessary and cleaned up.
