[PATCH v1 0/3] RISC-V: Fix a few kexec_file_load(2) failures

[Petr Tesařík]

Hi,

oops. I wanted to _add_ the kexec ML to all other recipients, but I
somehow screwed up, so this version is sent _only_ to the kexec ML. If
you reply here, the other recipients will not see your reply. The real
thread is here:

I'm sorry
Petr T
