Memory reservation for crashkernel could fail if there are holes around
kdump kernel offset (128M). Fail gracefully in such cases and print an
error message.

In the quest to remove all stack VLA usage from the kernel[1], this
switches to using a stack size large enough for the saved routine and
adds a sanity check making sure the routine doesn't overflow into the
0x600 exception handler.

If a process exits without doing proper cleanup, there's a window
where an opencapi device can try to access the memory of the dying
process and may trigger a page fault. That's an expected scenario and
the ocxl driver holds a reference on the mm_struct of the process
until the opencapi device is notified of the process exiting.
However, if mm_users is already at 0, i.e. the address space of the
process has already been destroyed, the driver shouldn't try resolving
the page fault, as it will fail, but it can also try accessing already
freed data.
It is fixed by only calling the bottom half of the page fault handler
if mm_users is greater than 0 and get a reference on mm_users instead
of mm_count. Otherwise, we can safely return a translation fault to
the device, as its associated memory context is being removed. The
opencapi device will be properly cleaned up shortly after when closing
the file descriptors.

There is a buffer overflow in dscr_inherit_test.c test. In main(), strncpy()'s
third argument is the length of the source, not the size of the destination
buffer, which makes strncpy() behaves like strcpy(), causing a buffer overflow
if argv[0] is bigger than LEN_MAX (100).
This patch maps 'prog' to the argv[0] memory region, removing the static
allocation and the LEN_MAX size restriction.

We use PHB in mode1 which uses bit 59 to select a correct DMA window.
However there is mode2 which uses bits 59:55 and allows up to 32 DMA
windows per a PE.
Even though documentation does not clearly specify that, it seems that
the actual hardware does not support bits 59:55 even in mode1, in other
words we can create a window as big as 1<<58 but DMA simply won't work.
This reduces the upper limit from 59 to 55 bits to let the userspace know
about the hardware limits.

64-bit ELF v2 ABI specification for POWER describes, on section "General
Stack Frame Requirements", that the stack should use the following
instructions when compiled with backchain:
mflr r0
std r0, 16(r1)
stdu r1, -XX(r1)
Where XX is the frame size for that function, and this is the value
checkstack.pl will find the stack size for each function.
This patch also simplifies the entire Powerpc section, since just two
type of instructions are used, 'stdu' for 64 bits and 'stwu' for 32 bits
platform.

Due to recent refactoring in EEH in:
commit b9fde58db7e5 ("powerpc/powernv: Rework EEH initialization on
powernv")
a misleading message was seen in the kernel message buffer:
[ 0.108431] EEH: PowerNV platform initialized
[ 0.589979] EEH: No capable adapters found
This happened due to the removal of the initialization delay for powernv
platform.
Even though the EEH infrastructure for the devices is eventually
initialized and still works just fine the eeh device probe step is
postponed in order to assure the PEs are created. Later
pnv_eeh_post_init does the probe devices job but at that point the
message was already shown right after eeh_init flow.
This patch introduces a new flag EEH_POSTPONED_PROBE to represent that
temporary state and avoid the message mentioned above and showing the
follow one instead:
[ 0.107724] EEH: PowerNV platform initialized
[ 4.844825] EEH: PCI Enhanced I/O Error Handling Enabled

Use new return type vm_fault_t for fault handler. For now, this is
just documenting that the function returns a VM_FAULT value rather
than an errno. Once all instances are converted, vm_fault_t will
become a distinct type.
Ref-> commit 1c8f422059ae ("mm: change return type to vm_fault_t")
There is an existing bug when vm_insert_pfn() can return ENOMEM which
was ignored and VM_FAULT_NOPAGE returned as default. The new inline
vmf_insert_pfn() has removed this inefficiency by returning correct
vm_fault_ type.

"Small set of fixes for this series. Mostly just minor fixes, the only
oddball in here is the sg change.
The sg change came out of the stall fix for NVMe, where we added a
mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
sort-of ruins that, since we'd need to account for that. That's
actually a generic problem, since lots of drivers need to allocate SG
lists. So this just removes support for CONFIG_SG_DEBUG, which I added
back in 2007 and to my knowledge it was never useful.

As suggested by Nick Piggin it seems we can drop the -ffunction-sections
compile flag, now that the kernel uses thin archives. Testing with 32-
and 64-bit kernel showed no difference in kernel size.

This was introduced more than a decade ago when sg chaining was
added, but we never really caught anything with it. The scatterlist
entry size can be critical, since drivers allocate it, so remove
the magic member. Recently it's been triggering allocation stalls
and failures in NVMe.
