This is based on the shmem version, but it has diverged quite
a bit. We have no swap to worry about, nor the new file sealing.
Add synchronication via the fault mutex table to coordinate
page faults, fallocate allocation and fallocate hole punch.
What this allows us to do is move physical memory
hugetlb page faults are currently synchronized by the table of
mutexes (htlb_fault_mutex_table). fallocate code will need to
synchronize with the page fault code when it allocates or
deletes pages. Expose interfaces so that fallocate operations
can be synchronized with page faults. Minor name ch
Areas hole punched by fallocate will not have entries in the

Hi Greg,
This patchset replaces the printk(KERN_DEBUG) uses in the tty core
with a common tty_debug(tty, ...) base macro, folding in the common
elements of tty name and function name.
The many inline #ifdef TTY_SOME_DEBUG_FLAG printk's are replaced
with macro equivalents which reduce to tty_debug
Opens of /dev/ptmx don't use tty_open() so debug messages are
not printed for those opens; print a debug message with the
open count (which must always be 1) if TTY_DEBUG_HANGUP is defined.
NB: Each tty core source file undefs support for debug messages.
The relevant source file must be patched/ed
Replace tty_ldisc_debug() macro definition; substitute with equivalent

Now there's two kexec load syscall, one is kexec_load another is
kexec_file_load, kexec_file_load has been splited as kernel/kexec_file.c.
In this patch I split kexec_load syscall code to kernel/kexec.c.
And add a new kconfig option KEXEC_CORE, so we can disable kexec_load
and use kexec_file_load

Split kexec_file syscall related code to another file kernel/kexec_file.c
so that the #ifdef CONFIG_KEXEC_FILE in kexec.c can be dropped.
Sharing variables and functions are moved to kernel/kexec_internal.h per
suggestion from Vivek and Petr.

in_crash_kexec is only useful for kdump, it will not be used without
CONFIG_KEXEC_CORE, thus remove the #else section

Previously Theodore Ts'o brought up an issue about kexec_load syscall bypassing
signature verification:
https://lkml.org/lkml/2015/6/14/280
Because we have two kexec load syscall, one kexec_load, another kexec_file_load,
the latter one was introduced by Vivek Goyal, it is mainly for supporting UEF

The advance of the 'read' buffer index belongs in the outer
flip buffer consume loop, with the other buffer index arithmetic.

Clarify flip buffer producer/consumer operation; the use of
smp_load_acquire() and smp_store_release() more clearly indicates
which memory access requires a barrier.
