v2:
- minor naming updates
Vincent Guittot (3):
sched: Stop nohz stats when decayed
sched: reduce the periodic update
When NEWLY_IDLE load balance is not triggered, we might need to update the
blocked load anyway. We can kick an ilb so an idle CPU will take care of
updating blocked load or we can try to update them locally before entering
idle. In the latter case, we reuse part of the nohz_idle_balance.

Instead of using the cfs_rq_is_decayed() which monitors all *_avg
and *_sum, we create a cfs_rq_has_blocked() which only takes care of
util_avg and load_avg. We are only interested by these 2 values which are
decaying faster than the *_sum so we can stop the periodic update earlier.
Signed-off-by:
Stopped the periodic update of blocked load when all idle CPUs have fully
decayed. We introduce a new nohz.has_blocked that reflect if some idle
CPUs has blocked load that have to be periodiccally updated. nohz.has_blocked
is set everytime that a Idle CPU can have blocked load and it is then clear

When page_mapping() is called and the mapping is dereferenced in
page_evicatable() through shrink_active_list(), it is possible for the
inode to be truncated and the embedded address space to be freed at
the same time. This may lead to the following race.

Presently sysrq key for xmon('x') is registered during kernel init

Linus, I have no strong opini
Before the purgatory is loaded several checks are done whether the ELF file
in kexec_purgatory is valid or not. These checks are incomplete. For
example they don't check for the total size of the sections defined in the
section header table or if the entry point actually points into the
purgatory.
This patch adds the kexec_file_load system call to s390 as well as the arch
specific functions common code requires to work. Loaders for the different
file types will be added later.

Add an ELF loader for kexec_file. The main task here is to do proper sanity
checks on the ELF file. Basically all other functionality was already

The current code uses the sh_offset field in purgatory_info->sechdrs to
store a pointer to the current load address of the section. Depending
whether the section will be loaded or not this is either a pointer into
purgatory_info->purgatory_buf or kexec_purgatory. This is not only a
violation of the

For s390 new kernels are loaded to fixed addresses in memory before they
are booted. With the current code this is a problem as it assumes the
kernel will be loaded to an 'arbitrary' address. In particular,

Which ones? Documenting it, at least in the commit message, would seem
useful. Ou
kexec_file_load needs to prepare the new kernels before they are loaded.
For that it has to know the offsets in head.S, e.g. to register the new
command line. Unfortunately there are no macros right now defining those
offsets. Define them now.

To update the entry point there is an extra loop over all section headers
although this can be done in the main loop. So move it there and eliminate
the extra loop and variable to store the 'entry section index'.
Also, in the main loop, move the usual case, i.e. non-bss section, out of
the extra i
The main loop currently uses quite a lot of variables to update the section
headers. Some of them are unnecessary. So clean them up a little.

The kexec_purgatory buffer is read-only. Thus all pointers into
kexec_purgatory are read-only, too. Point this out by explicitly marking
purgatory_info->ehdr as 'const' and update the comments in purgatory_info.

When inspecting __kexec_load_purgatory you find that it has two tasks
1) setting up the kexec_buffer for the new kernel and,
2) setting up pi->sechdrs for the final load address.
The two tasks are independent of each other. To improve readability split

The stripped purgatory does not contain a symtab. So when looking for

Hi everybody
resending the series as there was no reaction, yet. Furthermore i was told
that Andrew and the x86 list should also be CCed, so welcome.
No changes made to the patches since first time i sent them. The patches
apply to the current master (v4.16-rc1).
Thanks
Philipp
