ef6673e836 thermal/drivers/qcom/lmh: Add sc8180x compatible 
The LMh instances in the Qualcomm SC8180X platform looks to behave
similar to those in SM8150, add additional compatibles to allow
platform specific behavior to be added if needed.

2d37f5c90b thermal/drivers/rz2gl: Fix OTP Calibration Register values 
As per the latest RZ/G2L Hardware User's Manual (Rev.1.10 Apr, 2022),
the bit 31 of TSU OTP Calibration Register(OTPTSUTRIM) indicates
whether bit [11:0] of OTPTSUTRIM is valid or invalid.

This patch updates the code to reflect this change.

077df623c8 tools/thermal: Add thermal daemon skeleton 
This change provides a simple daemon skeleton. It is an example of how
to use the thermal library which wraps all the complex code related to
the netlink and transforms it into a callback oriented code.

The goal of this skeleton is to give a base brick for anyone
interested in writing its own thermal engine or as an example to rely
on to write its own thermal monitoring implementation.

In the future, it will evolve with more features and hopefully more
logic.

3277e022a1 thermal/drivers/rcar_thermal: Use platform_get_irq_optional() to get the interrupt 
platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypasses the hierarchical setup and messes up the
irq chaining.

In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq_optional().

leads some resource leaked, so adjust the sequence to handle the error
correctly, and if pxa3xx_gcu_add_buffer() fails, pxa3xx_gcu_free_buffers()

58606220a2 drm/i915: Fix CFI violation with show_dynamic_id() 
When an attribute group is created with sysfs_create_group(), the
->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show()
callback to kobj_attr_show(). kobj_attr_show() uses container_of() to
get the ->show() callback from the attribute it was passed, meaning the
->show() callback needs to be the same type as the ->show() callback in
'struct kobj_attribute'.

However, show_dynamic_id() has the type of the ->show() callback in
'struct device_attribute', which causes a CFI violation when opening the
'id' sysfs node under drm/card0/metrics. This happens to work because
the layout of 'struct kobj_attribute' and 'struct device_attribute' are
the same, so the container_of() cast happens to allow the ->show()
callback to still work.

Change the type of show_dynamic_id() to match the ->show() callback in
'struct kobj_attributes' and update the type of sysfs_metric_id to
match, which resolves the CFI violation.

This patch fixes a bug where GEN1 VMs doesn't allow resolutions greater
than 64 MB size (eg 7680x4320). Unnecessary PCI check limits Gen1 VRAM
to legacy PCI BAR size only (ie 64MB). Thus any, resolution requesting
greater then 64MB (eg 7680x4320) would fail. MMIO region assigning this
memory shouldn't be limited by PCI bar size.

47f33de4aa x86/sev: Mark the code returning to user space as syscall gap 
When returning to user space, %rsp is user-controlled value.

If it is a SNP-guest and the hypervisor decides to mess with the
code-page for this path while a CPU is executing it, a potential #VC
could hit in the syscall return path and mislead the #VC handler.

So make ip_within_syscall_gap() return true in this case.
