With new handling of coalescing tables, we can install the block entry
before unmap of the old table mappings. So make the installation in
stage2_map_walk_table_pre(), and elide the installation from function
stage2_map_walk_table_post().

commit 76e2fc63ca40977af893b724b00cc2f8e9ce47a4 upstream.
Set the maximum DIE per package variable on AMD using the
NodesPerProcessor topology value. This will be used by RAPL, among
others, to determine the maximum number of DIEs on the system in order
to do per-DIE manipula

Nicolas/Ludovic, can one of you review and ACK this patch set?

In a x86 machine, an additional device can be described
inside the BIOS ACPI tables.
For example, an I2C GPIO expander, a LED, etc.,
can be successfully declared in ACPI, so that the related
device driver can start automatically at the boot.
But for the SPI NOR devices, the ACPI description works

commit 7e6d9788aa02333a4353058816d52b9a90aae0d3 upstream.
When the conversion was done to use devm_iio_kfifo_allocate(), a call to
iio_kfifo_free() was omitted (to be removed).
This change removes it.

[Why]
Find out when we try to disable CRC calculation,
crc generation is still enabled. Main reason is
that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.
[How]

Currently, loop device has only one global lock: loop_ctl_mutex.
This becomes hot in scenarios where many loop devices are used.
Scale it by introducing per-device lock: lo_mutex that protects
modifications of all fields in struct loop_device.
Keep loop_ctl_mutex to protect global data: loop_ind
