The hyp-stub's el1_sync code doesn't do very much, this can easily fit

With this, all of the hyp-stubs behaviour is contained in its vectors.
This lets kexec and hibernate copy the hyp-stub when they need its

Currently, during kexec load we are copying relocation function and
flushing it. However, we can also flush kexec relocation buffers and
if new kernel image is already in place (i.e. crash kernel), we can
also flush the new kernel image itself.

This header contains only cpu_soft_restart() which is never used directly
anymore. So, remove this header, and rename the helper to be
cpu_soft_restart().

Now that kexec does its relocations with the MMU enabled, we no longer
need to clean the relocation data to the PoC.

Currently, relocation code declares start and end variables
which are used to compute its size.
The better way to do this is to use ld script incited, and put relocation
function in its own section.

To perform the kexec relocations with the MMU enabled, we need a copy
of the linear map.
Create one, and install it from the relocation code. This has to be done
from the assembly code as it will be idmapped with TTBR0. The kernel
runs in TTRB1, so can't use the break-before-make sequence on the m

I might bikeshed the suffix ".o.orig" instead of ".obj".

Hi Masami,
Jakub reported a bug with kretprobe stack traces -- wondering if you've gotten
any bug reports related to stack traces being broken for kretprobes.
I think (can't prove) this used to work:
# bpftrace -e 'kretprobe:__tcp_retransmit_skb { @[kstack()] = count() }'

The MIPS Poly1305 implementation is generic MIPS code written such as to
support down to the original MIPS I and MIPS III ISA for the 32-bit and
64-bit variant respectively. Lift the current limitation then to enable
code for MIPSr1 ISA or newer processors only and have it available for
all MI
Hi Linus,
Two misc fixes that don't belong in other branches:
- Fix a regression with ia64 signals, introduced by the
TIF_NOTIFY_SIGNAL change in 5.11.
- Fix the current swapfile regression from this merge window.
Please pull!

Port enable is not complete until ACK = 0. Change
__afu_port_enable() to guarantee that the enable process
is complete by polling for ACK == 0.
