[Xen-devel] [PATCH v8 0/7] misc safety certification fixes

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

This version of the series replaces linker symbols usage in C code with
new uintptr_t variables set in assembly.

Due to the symbols renaming (_start becomes start_) the textual
difference is larger than before. However, there are very few meaningful
changes compared to the latest version of this series that used unsigned
longs. Meaningful changes are highlighted in the patch description.

Cheers,

Stefano
