ca9d081b49 zram: fix up permission for the hot_add sysfs file
Commit 75a2d4226b ("driver core: class: mark the struct class for
sysfs callbacks as constant") changed the attribute to use
CLASS_ATTR_RO() which changed the permission from 0400 to 0444.  But
this atribute is "special" in that reading it modifies the system state,
so it MUST be set to 0400 so that only root processes can muck around
with it.

Fix this all up, AND document this so that I don't change it again in
3-4 years when I stumble across it and wonder why it's an open-coded
_ATTR() macro.

e9523a0d81 tick/common: Align tick period with the HZ tick.
With HIGHRES enabled tick_sched_timer() is programmed every jiffy to
expire the timer_list timers. This timer is programmed accurate in
respect to CLOCK_MONOTONIC so that 0 seconds and nanoseconds is the
first tick and the next one is 1000/CONFIG_HZ ms later. For HZ=250 it is
every 4 ms and so based on the current time the next tick can be
computed.

This accuracy broke since the commit mentioned below because the jiffy
based clocksource is initialized with higher accuracy in
read_persistent_wall_and_boot_offset(). This higher accuracy is
inherited during the setup in tick_setup_device(). The timer still fires
every 4ms with HZ=250 but timer is no longer aligned with
CLOCK_MONOTONIC with 0 as it origin but has an offset in the us/ns part
of the timestamp. The offset differs with every boot and makes it
impossible for user land to align with the tick.

Align the tick period with CLOCK_MONOTONIC ensuring that it is always a
multiple of 1000/CONFIG_HZ ms.

84f650e632 wifi: iwlwifi: mvm: remove per-STA MFP setting
When we first add the STA before sending an authentication
frame this is false. However, in some cases such as FT or
certainly in MLO link switch scenarios, it will be true.

If it happens to be true, it causes a firmware assert (in
LMAC, 0x2528), because the same bit is used by the firmware
for tracking this setting as well as for tracking if the
management key has been installed, and then we get this
assert from the firmware when installing the MFP key as it
thinks it has already been installed.

Remove the setting for now, until the firmware disentangles
the two. We should be able to set it, in fact we should be
setting it speculatively before authentication/association,
to avoid processing management frames that should have been
protected/encrypted before the key is set.

These got*, plt* and .text.ftrace_trampoline sections specified for
LoongArch have non-zero addressses. Non-zero section addresses in a
relocatable ELF would confuse GDB when it tries to compute the section
offsets and it ends up printing wrong symbol addresses. Therefore, set
them to zero, which mirrors the change in commit 5d8591bc0f
("arm64 module: set plt* section addresses to 0x0").

dce5ea1d0f LoongArch: Mark 3 symbol exports as non-GPL
vm_map_base, empty_zero_page and invalid_pmd_table could be accessed
widely by some out-of-tree non-GPL but important file systems or drivers
(e.g. OpenZFS). Let's use EXPORT_SYMBOL() instead of EXPORT_SYMBOL_GPL()
to export them, so as to avoid build errors.

1, Details about vm_map_base:

This is a LoongArch-specific symbol and may be referenced through macros
PCI_IOBASE, VMALLOC_START and VMALLOC_END.

2, Details about empty_zero_page:

As it stands today, only 3 architectures export empty_zero_page as a GPL
symbol: IA64, LoongArch and MIPS. LoongArch gets the GPL export by
inheriting from MIPS, and the MIPS export was first introduced in commit
497d2adcbf ("[MIPS] Export empty_zero_page for sake of the ext4
module."). The IA64 export was similar: commit a7d57ecf42 ("[IA64]
Export three symbols for module use") did so for kvm.

In both IA64 and MIPS, the export of empty_zero_page was done for
satisfying some in-kernel component built as module (kvm and ext4
respectively), and given its reasonably low-level nature, GPL is a
reasonable choice. But looking at the bigger picture it is evident most
other architectures do not regard it as GPL, so in effect the symbol
probably should not be treated as such, in favor of consistency.

3, Details about invalid_pmd_table:

Keep consistency with invalid_pte_table and make it be possible by some
modules.

16c52e5030 LoongArch: Make WriteCombine configurable for ioremap()
LoongArch maintains cache coherency in hardware, but when paired with
LS7A chipsets the WUC attribute (Weak-ordered UnCached, which is similar
to WriteCombine) is out of the scope of cache coherency machanism for
PCIe devices (this is a PCIe protocol violation, which may be fixed in
newer chipsets).

This means WUC can only used for write-only memory regions now, so this
option is disabled by default, making WUC silently fallback to SUC for
ioremap(). You can enable this option if the kernel is ensured to run on
hardware without this bug.

Kernel parameter writecombine=on/off can be used to override the Kconfig
option.
