KEXEC: Allocate crash structures in low memory
On 64bit Xen with 32bit dom0 and crashkernel, xmalloc'ing items such
as the CPU crash notes will go into the xenheap, which tends to be in
upper memory. This causes problems on machines with more than 64GB
(or 4GB if no PAE support) of ram as the crashkernel physically cant
access the crash notes.
The solution is to force Xen to allocate certain structures in lower
memory. This is achieved by introducing two new command line
parameters; low_crashinfo and crashinfo_maxaddr. Because of the
potential impact on 32bit PV guests, and that this problem does not
exist for 64bit dom0 on 64bit Xen, this new functionality defaults to
the codebase's previous behavior, requiring the user to explicitly
add extra command line parameters to change the behavior.
This patch consists of 3 logically distinct but closely related
changes.
1) Add the two new command line parameters.
2) Change crash note allocation to use lower memory when instructed.
3) Change the conring buffer to use lower memory when instructed.
There result is that the crash notes and console ring will be placed
in lower memory so useful information can be recovered in the case of
a crash.

KEXEC: Allocate crash notes on boot
Currently, the buffers for crash notes are allocated per CPU when a
KEXEC_CMD_kexec_get_range hypercall is made, referencing the CPU in
question. This has certain problems including not being able to
allocate the crash buffers if the host is out of memory when crashing.
In addition, my forthcoming code to support 32bit kdump kernels on
64bit Xen on large (>64GB) boxes will require some guarentees as to
where the crash note buffers are actually allocated in physical
memory. This is far easier to sort out at boot time, rather than
after dom0 has been booted and potentially using the physical memory
required.
Therefore, allocate the crash note buffers at boot time.
Changes since v6:
* Tweak kexec_init() to use xzmalloc_array(), and to defer
registering the
crashdump keyhandler until the crash notes have been successfully
allocated.
Changes since v5:
* Introduce sizeof_cpu_notes to move calculation of note size into a
separate location.
* Tweak sizeof_note() to return size_t rather than int, as it is a
function based upon sizeof().
Changes since v4:
* Replace the current cpu crash note scheme of using void pointers
and hand calculating the size each time is needed, by a range
structure containing a pointer and a size. This removes duplicate
times where the size is calculated.
* Tweak kexec_get_cpu(). Don't fail if a cpu is offline because it
may already have crash notes, and may be up by the time a crash
happens. Split the error conditions up to return ERANGE for an
out-of-range cpu request rather than EINVAL. Finally, returning a
range of zeros is acceptable, so do this in preference to failing.
Changes since v3:
* Alter the spinlocks to avoid calling xmalloc/xfree while holding
the lock.
* Tidy up the coding style used.
Changes since v2:
* Allocate crash_notes dynamically using nr_cpu_ids at boot time,
rather than statically using NR_CPUS.
* Fix the incorrect use of signed integers for cpu id.
* Fix collateral damage to do_crashdump_trigger() and
crashdump_trigger_handler caused by reordering sizeof_note() and
setup_note()
* Tweak the issue about returing -ENOMEM from kexec_init_cpu_note().
No functional change.
* Change kexec_get_cpu() to attempt to allocate crash note buffers
in case we have more free memory now than when the pcpu came up.
* Now that there are two codepaths possibly allocating crash notes,
protect the allocation itself with a spinlock.
Changes since v1:
* Use cpu hotplug notifiers to handle allocating of the notes
buffers rather than assuming the boot state of cpus will be the
same as the crash state.
* Move crash_notes from being per_cpu. This is because the kdump
kernel elf binary put in the crash area is hard coded to physical
addresses which the dom0 kernel typically obtains at boot time.
If a cpu is offlined, its buffer should not be deallocated because
the kdump kernel would read junk when trying to get the crash
notes. Similarly, the same problem would occur if the cpu was
re-onlined later and its crash notes buffer was allocated
elsewhere.
* Only attempt to allocate buffers if a crash area has been
specified. Else, allocating crash note buffers is a waste of
space. Along with this, change the test in kexec_get_cpu to
return -EINVAL if no buffers have been allocated.

Memory sharing: better handling of ENOMEM while unsharing
If unsharing fails with ENOMEM, we were:
- leaving the list of gfns backed by the shared page in an inconsistent state
- cycling forever on the hap page fault handler.
- Attempting to produce a mem event (which could sleep on a wait queue)
while holding locks.
- Not checking, for all callers, that unshare could have indeed failed.
Fix bugs above, and sanitize callers to place a ring event in an unlocked
context, or without requiring to go to sleep on a wait queue.
A note on the rationale for unshare error handling:
1. Unshare can only fail with ENOMEM. Any other error conditions BUG_ON()
2. We notify a potential dom0 helper through a mem_event ring. But we
allow the notification to not go to sleep. If the event ring is full
of ENOMEM warnings, then the helper will already have been kicked enough.
3. We cannot "just" go to sleep until the unshare is resolved, because we
might be buried deep into locks (e.g. something -> copy_to_user ->
__hvm_copy)
4. So, we make sure we:
4.1. return an error
4.2. do not corrupt memory shared with other guests
4.3. do not corrupt memory private to the current guest
4.4. do not corrupt the hypervisor memory sharing meta data
4.5. let the guest deal with the error, if propagation will reach that far

Under extreme congestion conditions, generating a mem event may put the vcpu to
sleep on a wait queue if the ring is full. This is generally desirable, although
fairly convoluted to work with, since sleeping on a wait queue requires a
non-atomic context (i.e. no locks held).
Introduce an allow_sleep flag to make this optional. The default API remains
such that all current callers set allow_sleep to true and thus will sleep if
necessary.
The end-use is for cases in which loss of guest mem events is tolerable. One
such consumer to be added later is the unsharing code under ENOMEM conditions.
