stmmac registers a 32-bit. u32 is unsigned int. The use of BIT() and
GENMASK() leads to integer promotion to unsigned long in expressions
such as:
u32 old = foo;
dev_info(dev, "%08x %08x\n", old, old & BIT(1));
resulting in arg2 being accepted as compatible with the format string
and arg3 warning that the argument does not match (because the former
is unsigned int, and the latter is unsigned long.)
Fix this by defining 32-bit register bits using BIT_U32() and
GENMASK_U32() macros.

RTL8127ATF supports a SFP+ port for fiber modules (10GBASE-SR/LR/ER/ZR and
DAC). The list of supported modes was provided by Realtek. According to the
r8127 vendor driver also 1G modules are supported, but this needs some more
complexity in the driver, and only 10G mode has been tested so far.
Therefore mainline support will be limited to 10G for now.
The SFP port signals are hidden in the chip IP and driven by firmware.
Therefore mainline SFP support can't be used here.

This PHY driver is used by the RTL8127ATF support in r8169.

Motorcomm YT6801 is a PCIe ethernet controller based on DWMAC4 IP. It
integrates an GbE phy, supporting WOL, VLAN tagging and various types
of offloading. It ships an on-chip eFuse for storing various vendor
configuration, including MAC address.
This patch adds basic glue code for the controller, allowing it to be
set up and transmit data at a reasonable speed. Features like WOL could
be implemented in the future.

norm_set_tx_desc_len_on_ring() incorrectly tests the buffer length,
leading to a length of 2048 being squeezed into a bitfield covering
bits 10:0 - which results in the buffer 1 size being zero.
If this field is zero, buffer 1 is ignored, and thus is equivalent to
transmitting a zero length buffer.
The path to norm_set_tx_desc_len_on_ring() is only possible when the
hardware does not support enhanced descriptors (plat->enh_desc clear)
which is dependent on the hardware.

In dwmac4_wrback_get_rx_status(), the code extracts the PTP message
type from receive descriptor 1 using the dwmac enhanced descriptor
definitions:
message_type = (rdes1 & ERDES4_MSG_TYPE_MASK) >> 8;
This is defined as:
#define ERDES4_MSG_TYPE_MASK GENMASK(11, 8)
The correct definition is RDES1_PTP_MSG_TYPE_MASK, which is also
defined as:
#define RDES1_PTP_MSG_TYPE_MASK GENMASK(11, 8)
Use the correct definition, converting to use FIELD_GET() to extract
it without needing an open-coded shift right that is dependent on the
mask definition.
As this change has no effect on the generated code, there is no need
to treat this as a bug fix.

In dwmac4_debug(), the wrong shift is used with the RXFSTS mask:
#define MTL_DEBUG_RXFSTS_MASK GENMASK(5, 4)
#define MTL_DEBUG_RXFSTS_SHIFT 4
#define MTL_DEBUG_RRCSTS_SHIFT 1
u32 rxfsts = (value & MTL_DEBUG_RXFSTS_MASK)
>> MTL_DEBUG_RRCSTS_SHIFT;
where rxfsts is tested against small integers 1 .. 3. This results in
the tests always failing, causing the "mtl_rx_fifo__fill_level_empty"
statistic counter to always be incremented no matter what the fill
level actually is.
Fix this by using FIELD_GET() and remove the unnecessary
MTL_DEBUG_RXFSTS_SHIFT definition as FIELD_GET() will shift according
to the least siginificant set bit in the supplied field mask.

Unlike UBLK_CMD_STOP_DEV, this command does not disrupt existing users.
New opens are blocked only after disk_openers has reached zero; if the

The ub->block_open flag is used only to close a race with an in-progress

tempX_crit and GPU max temperature limit as temp2_max.
Update Xe hwmon documentation with above entries.
v2:
- Resolve a documentation warning.
- Address below review comments from Raag.
- Update date and kernel version in Xe hwmon documentation.
- Remove explicit disable of has_mbx_thermal_info for unsupported
platforms.
- Remove unnecessary default case in switches.
- Remove obvious comments.
- Use TEMP_LIMIT_MAX to compute number of dwords needed in
xe_hwmon_thermal_info.
- Remove THERMAL_LIMITS_DWORDS macro.
- Use has_mbx_thermal_info for checking thermal mailbox support.
v3:
- Address below minor comments. (Raag)
- Group new temperature attributes with existing temperature attributes
as per channel index in Xe hwmon documentation.
- Rename enums of xe_temp_limit to improve clarity.
- Use DIV_ROUND_UP to calculate dwords needed for temperature limits.
- Use return instead of breaks in xe_hwmon_temp_read.
- Minor aesthetic refinements.
v4:
- Remove a redundant break. (Raag)
- Update drm_dbg to drm_warn to inform user of unavailability for
thermal mailbox on expected platforms.

Now that the AES library's performance has been improved, replace
aes_generic.c with a new file aes.c which wraps the AES library.
In preparation for making the AES library actually utilize the kernel's
existing architecture-optimized AES code including AES instructions, set
the driver name to "aes-lib" instead of "aes-generic". This mirrors
what's been done for the hash algorithms. Update testmgr.c accordingly.
Since this removes the crypto_aes_set_key() helper function, add
temporary replacements for it to arch/arm/crypto/aes-cipher-glue.c and
arch/arm64/crypto/aes-cipher-glue.c. This is temporary, as that code
will be migrated into lib/crypto/ in later commits.

We're improving NAN support, but NAN datapath support also
means we need to change some other things, e.g. related to
rate control. Remove NAN by default again from hwsim since
it's the much newer feature.

strncpy() is deprecated [1] for NUL-terminated destination buffers since
it does not guarantee NUL termination. Remove the manual NUL termination
and replace strncpy() with strscpy() to ensure NUL termination of the
destination buffer.
Using strscpy_pad() to retain the NUL-padding behavior of strncpy() is
not needed because ->fw_ver is only used as a C-string.

The "i" iterator variable is used to count two different things but
unfortunately we can't store two different numbers in the same variable.
Use "i" for the outside loop and "j" for the inside loop.

The struct ieee80211_vif contains trailing space for vif driver data,
when struct ieee80211_vif is allocated, the total memory size that is
allocated is sizeof(struct ieee80211_vif) + size of vif driver data.
The size of vif driver data is set by each WiFi driver as needed.
The RSI911x driver does not set vif driver data size, no trailing space
for vif driver data is therefore allocated past struct ieee80211_vif .
The RSI911x driver does however use the vif driver data to store its
vif driver data structure "struct vif_priv". An access to vif->drv_priv
leads to access out of struct ieee80211_vif bounds and corruption of
some memory.
In case of the failure observed locally, rsi_mac80211_add_interface()
would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;
vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member
struct list_head new_flows . The flow = list_first_entry(head, struct
fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus
address, which when accessed causes a crash.
The trigger is very simple, boot the machine with init=/bin/sh , mount
devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1",
"ip link set wlan0 down" and the crash occurs.
Fix this by setting the correct size of vif driver data, which is the
size of "struct vif_priv", so that memory is allocated and the driver
can store its driver data in it, instead of corrupting memory around
it.

Commit 32ece31db4df ("ACPI: PM: s2idle: Only retrieve constraints
when needed"), that attempted to avoid useless evaluation of LPS0 _DSM
Function 1 in lps0_device_attach(), forgot to add checks for
lps0_device_handle and sleep_no_lps0 to acpi_s2idle_begin_lps0()
where they should be done before calling lpi_device_get_constraints()
or lpi_device_get_constraints_amd().
Add the missing checks.
