+Redefine default library directory for aarch64.
+
+Packages use 'aarch64-poky-linux-gcc -print-multi-os-directory' to get the
+value of install directory. The value is set by MULTILIB_OSDIRNAMES and default
+is '/lib64'. Add the dynamic linker ld-linux-aarch64.so.1 from package eglibc
+is installed to /lib64.
+
+But the default dynamic linker defined in gcc/config/aarch64/aarch64-linux.h
+is:
+
+#define GLIBC_DYNAMIC_LINKER "/lib/ld-linux-aarch64%{mbig-endian:_be}.so.1"
+
+Then cause all the ELF files fail to launch because fail to find the linker.

+Subject: [PATCH 01/11] target-arm: Collect up the debug cp register
+ definitions
+
+At the moment we have a mixed set of mostly dummy register
+definitions for various debug related registers which have
+been added piecemeal in order to get Linux kernels to boot.
+In preparation for actually implementing debug support,
+bring them all together into one place.
+
+This commit doesn't change behaviour: we still expose
+exactly the same registers and behaviour to the guest
+in all configurations.

+Subject: [PATCH 06/11] target-arm: Correctly handle PSTATE.SS when taking
+ exception to AArch32
+
+When an exception is taken to AArch32, we must clear the PSTATE.SS
+bit for the exception handler, and must also ensure that the SS bit
+is not set in the value saved to SPSR_<mode>. Achieve both of these
+aims by clearing the bit in uncached_cpsr before saving it to the SPSR.
