commit 553de072d2750a4c60ad5b4d8acb13af2bf47b98 Author: Julien Grall <julien.grall@xxxxxxx> AuthorDate: Wed Oct 31 18:13:01 2018 +0000 Commit: Stefano Stabellini <sstabellini@xxxxxxxxxx> CommitDate: Fri Nov 9 10:14:30 2018 -0800 xen/arm: Move HSR defines in a new header hsr.h The HSR defines are pretty much self-contained and not necessary to be included everywhere in Xen. So move them in a new header hsr.h.
