Hi,

The following patches merge the jdk8 tree up to jdk8u40-b23.

http://people.linaro.org/~edward.nevill/patches/jaxp.patch
http://people.linaro.org/~edward.nevill/patches/jaxws.patch
http://people.linaro.org/~edward.nevill/patches/jdk.patch
http://people.linaro.org/~edward.nevill/patches/jdk8.patch
http://people.linaro.org/~edward.nevill/patches/langtools.patch
http://people.linaro.org/~edward.nevill/patches/nashorn.patch

The following are the aarch64 specific changes

http://people.linaro.org/~edward.nevill/patches/hotspot_aarch64.patch

There is just one aarch64 specific change which is to correct the logic
for saving FP registers on an expection (previously FP registers were
being saved when it wasn't necessary and not saved when it was). This
change has already bee pushed to jdk9 staging.

Tested with JTreg hotspot and langtools

Before merge (jdk8u40-b12)

hotspot: pass 615, fail 13, error 18
langtools: pass 3017, fail 1, error 30

After merge (jdk8u40-b23)

hotspot: pass 639, fail 9, error 22
langtools: pass 3044, error 29

OK to push?
Ed.
