- Thread-topic: [PATCH 0/5] xen/arm: Fixes and improvements to SMCCC
Hi Andrew,
While reviewing those patches i found out that cover letter is saying that the
serie has 5 patches but then the patches are number out of 6.
Is there a patch missing or something went wrong in the numbering and there is
actually on 5 patches ?
Regards
Bertrand
