Protect against what?
Protect against invalid memory accesses, mainly caused by bugs, I guess.
I meant just applying tight memory attributes, sorry for the
bad wording. I will change it in the next version.
Set sections alignment in linker script for the kernel decompressor
(boot/compressed/vmlinux.lds.S).
Do not talk about *what* the patch is doing in the commit message -
that
should be obvious from the diff itself. Rather, concentrate on the
*why*
it needs to be done.
Makes sense. I'll try to improve it before resubmitting.
Also introduce symbols that can be used to reference compressed
kernel blob section later in the later patches.
Introduce those with the respective patch that uses them. This one is
adding section alignment only and that's all that it should do.
Oh, good point, will do.
Thx.
Thanks,
