Peter, Frederic,
Here's a v2 of the patch series to fix the loadavg spikes I'm seeing
on a v3.12 based kernel, caused by delaying load sampling if a sample
period was crossed while in NO_HZ idle.
I tried to make the changelog for PATCH 1 clearer this time around by
incorporating suggestions from
If we crossed a sample window while in NO_HZ we will add LOAD_FREQ to
the pending sample window time on exit, setting the next update not
one window into the future, but two.
This situation on exiting NO_HZ is described by:
this_rq->calc_load_update < jiffies < calc_load_update
In this scenari

Many "embedded" architectures provide CMDLINE_FORCE to allow the kernel
to override the command line provided by an inflexible bootloader.
However there is currrently no way for the kernel to override the
initramfs image provided by the bootloader meaning there are still ways
for bootloaders to mak

This basically restores slightly modified version of original

The only modification is protection against 'address' overflow.

With 5-level paging randomization happens on P4D level instead of PUD.
Maximum amount of physical memory also bumped to 52-bits for 5-level
paging.

Most of things are in place and we can enable support of 5-level paging.
Enabling XEN with 5-level paging requires more work. The patch makes XEN
dependent on !X86_5LEVEL.

This patch introduces two new prctl(2) handles to manage maximum virtual
address available to userspace to map.
On x86, 5-level paging enables 56-bit userspace virtual address space.
Not all user space is ready to handle wide addresses. It's known that
at least some JIT compilers use higher bits i

We don't need extra virtual address space for ESPFIX, so it stays within
one PUD page table for both 4- and 5-level paging.

This patch adds support for 5-level paging during early boot.
It generalizes boot for 4- and 5-level paging on 64-bit systems with
compile-time switch between them.
