The macros TDX_ATTR_* and DEF_TDX_ATTR_* are related to TD attributes,
which are TD-scope attributes. Naming them as TDX_ATTR_* can be somewhat
confusing and might mislead people into thinking they are TDX global
things.
Rename TDX_ATTR_* to TDX_TD_ATTR_* to explicitly clarify they are
TD-scope things.

The TD scoped TDCS attributes are defined by bit positions. In the guest
side of the TDX code, the 'tdx_attributes' string array holds pretty
print names for these attributes, which are generated via macros and
defines. Today these pretty print names are only used to print the
attribute names to dmesg.
Unfortunately there is a typo in the define for the migratable bit.
Change the defines TDX_ATTR_MIGRTABLE* to TDX_ATTR_MIGRATABLE*. Update
the sole user, the tdx_attributes array, to use the fixed name.
Since these defines control the string printed to dmesg, the change is
user visible. But the risk of breakage is almost zero since it is not
exposed in any interface expected to be consumed programmatically.

The root cause of this bug is that when 'bpf_link_put' reduces the
refcount of 'shim_link->link.link' to zero, the resource is considered
released but may still be referenced via 'tr->progs_hlist' in
'cgroup_shim_find'. The actual cleanup of 'tr->progs_hlist' in
'bpf_shim_tramp_link_release' is deferred. During this window, another
process can cause a use-after-free via 'bpf_trampoline_link_cgroup_shim'.
Based on Martin KaFai Lau's suggestions, I have created a simple patch.
To fix this:
Add an atomic non-zero check in 'bpf_trampoline_link_cgroup_shim'.
Only increment the refcount if it is not already zero.
Testing:
I verified the fix by adding a delay in
'bpf_shim_tramp_link_release' to make the bug easier to trigger:
static void bpf_shim_tramp_link_release(struct bpf_link *link)
{
/* ... */
if (!shim_link->trampoline)
return;
+ msleep(100);
WARN_ON_ONCE(bpf_trampoline_unlink_prog(&shim_link->link,
shim_link->trampoline, NULL));
bpf_trampoline_put(shim_link->trampoline);
}
Before the patch, running a PoC easily reproduced the crash(almost 100%)
with a call trace similar to KaiyanM's report.
After the patch, the bug no longer occurs even after millions of
iterations.

Driver initializes delayed work and then registers interrupt handler
with devm interface. This means that device removal will not use a
reversed order, but first cancel pending work items and then, via devm
release handlers, free the interrupt.
The interrupt handler does not directly use/schedule work
items on the workqueue, however it updates the status of the battery
charger which might lead to calling power_supply_changed() and trigger
chain of calls leading to scheduling the work items. If this happens
during short time window after cancel_delayed_work_sync() in remove()
callback, the work would be rescheduled.
Avoid this by using devm interface to initialize and cancel work item,
thus having exactly reverse order during remove() in respect to rest of
the probe/cleanup paths. This is also more logical and readable code.

rely on hardcoded assumptions about the available reboot-modes.
Create a class 'reboot-mode' and a device under it. Use the name of the
registering driver as device name. Expose a sysfs interface under this
device to show available reboot mode arguments.
This results in the creation of:
/sys/class/reboot-mode/<driver>/reboot_modes

The MAX77759 incorporates the Maxim ModelGauge m5 algorithm. It, as
well as previous generations like m3 on max17047/max17050, requires
the host to save/restore some register values across power cycles to
maintain full accuracy. Extending the driver for such support is out of
