To restore big slabs of memory (more than 1G) via pipes we need
pipes to be able to carry such sizes, for this sake Andrey propose
to use kvmalloc calls. Looking into the code I didn't find a reason
why we can't do so, thus here is a patch.

I was investigating an issue with seabios >= 1.10 which stopped working
for nested KVM on Hyper-V. The problem appears to be in
handle_ept_violation() function: when we do fast mmio we need to skip
the instruction so we do kvm_skip_emulated_instruction(). This, however,

Add a minimal kernel config:
- localmodconfig done on a KVM VM
- all options are set to "=y" where possible
Several modules still exist:
./Documentation/filesystems/configfs/configfs_example_macros.ko
./Documentation/filesystems/configfs/configfs_example_explicit.ko
./Documentation/connector
Guys, if you have suggestions to improve minimal config, please send patches or
just tell me.

We saw excessive direct memory compaction triggered by skb_page_frag_refill.
This causes performance issues and add latency. Commit 5640f7685831e0
introduces the order-3 allocation. According to the changelog, the order-3
allocation isn't a must-have but to improve performance. B

What is it going to be use{d,ful} for?

Hello!
BTW, check this a few lines above:
gfp_head = gfp_mask;
if (gfp_head & __GFP_WAIT)
gfp_head |= __GFP_REPEAT;
What is this??
