+Subject: [PATCH] tests/ioctl_kvm_run.c: handle cpuid at the end of vcpu dentry
+
+Since Linux 4.16, kernel appends the cpuid as suffix to the entry
+for a kvm vcpu in /proc/$pid/fd like:
+
+    anon_inode:kvm-vcpu:0
+
+That was
+
+    anon_inode:kvm-vcpu
+
+This kernel change causes the test case failure on newer kernels.
+Update the test to deal with the new name as well as the old one.
+
+* tests/ioctl_kvm_run.c: Include unistd.h for using readlink(2).
+(vcpu_dev_should_have_cpuid): New function for detecting whether
+a proc entry for given fd has the cpuid suffix or not.
+(main): Trim vcpu_dev to remove the cpuid suffix if needed.
+(vcpu_dev): Remove const modifier.

+Subject: [PATCH] i18n: Blind fix attempt for std::bad_cast being thrown on
+ Windows
+
+Several reports on Steam and our forums point at std::bad_cast being
+thrown when accessing Preferences and the Multiplayer menu amongst
+others. It's possible that the locale configuration on those systems is
+not quite right, and compare() and icompare() are able to throw
+std::bad_cast when this happens as they both use std::use_facet().
+
+Note that much like the macOS/iOS version of icompare(), this stopgap
+patch doesn't attempt to provide any form of case-insensitive fallback
+and just uses a case-sensitive comparison instead.
