Add a kernel with LPAE

[anisse]

It would be nice to have the possibility to create bigger memory mappings, in particular when we want to overcommit a lot of memory in a a single process, or eventually use a lot of swap.

Would you consider enabling ARM_LPAE?

Hi @anisse, thank you for your suggestion,

No problem for me ping @aimxhaisse

Thanks @anisse !

I see no problem to enable it either.

Hmm, I 'm reconsidering it. LPAE might have a (small) performance impact, so it should only be enabled for all your customers if you find it acceptable. Also, what I said in the first post is wrong, since LPAE wouln't enlarge a single process virtual space, which is my goal; it only allows addressing more physical RAM, which isn't something useful on C1 servers that don't go over 2GB of RAM.

TBH, what I want is a 64 bits server, but I understand these are just ARMv7 machines.
