+Subject: acpi-cpufreq: Honor _PSD table setting on new AMD CPUs
+
+From: Wei Huang <wei.huang2@amd.com>
+
+commit 5368512abe08a28525d9b24abbfc2a72493e8dba upstream.
+
+acpi-cpufreq has a old quirk that overrides the _PSD table supplied by
+BIOS on AMD CPUs. However the _PSD table of new AMD CPUs (Family 19h+)
+now accurately reports the P-state dependency of CPU cores. Hence this
+quirk needs to be fixed in order to support new CPUs' frequency control.
+
+Fixes: acd316248205 ("acpi-cpufreq: Add quirk to disable _PSD usage on all AMD CPUs")

+Subject: ACPI / extlog: Check for RDMSR failure
+
+From: Ben Hutchings <ben@decadent.org.uk>
+
+commit 7cecb47f55e00282f972a1e0b09136c8cd938221 upstream.
+
+extlog_init() uses rdmsrl() to read an MSR, which on older CPUs
+provokes a error message at boot:
+
+ unchecked MSR access error: RDMSR from 0x179 at rIP: 0xcd047307 (native_read_msr+0x7/0x40)
+
+Use rdmsrl_safe() instead, and return -ENODEV if it fails.

+Subject: ACPI: video: use ACPI backlight for HP 635 Notebook
+
+From: Alex Hung <alex.hung@canonical.com>
+
+commit b226faab4e7890bbbccdf794e8b94276414f9058 upstream.
+
+The default backlight interface is AMD's radeon_bl0 which does not
+work on this system, so use the ACPI backlight interface on it
+instead.

+MIME-Version: 1.0

+
+commit ff5c89d44453e7ad99502b04bf798a3fc32c758b upstream.
+
+These two drivers do not provide remove method and use devres for
+allocation of other resources, yet they use led_classdev_register
+instead of the devres variant, devm_led_classdev_register.
+
+Fix this.

+Subject: NFS: fix nfs_path in case of a rename retry
+
+From: Ashish Sangwan <ashishsangwan2@gmail.com>
+
+commit 247db73560bc3e5aef6db50c443c3c0db115bc93 upstream.
+
+We are generating incorrect path in case of rename retry because
+we are restarting from wrong dentry. We should restart from the
+dentry which was received in the call to nfs_path.
