CA-142346: don't IPI all spinlock waiters (add patches to series)
CP-10412: refresh 64-bit kernel configuration

The kernel configuration should always be updated with make menuconfig
(or similar) and not by editing the configuration file directly.
Refresh the configuration so it correctly includes the options that
are selected or now enabled by default.
CP-10412: remove the 32-bit kernel configuration

This configuration is not maintained and we're never going to need a
32-bit kernel.
CP-10412: increase kernel log buffer to 256 KiB

Hosts with lots of devices (e.g., NetScaler SDX) log too much before
userspace has a chance to save the initial log buffer.
CA-153450: Revert "CP-9934: Safe grant unmap (unmap only when no longer in use)"

This reverts commit 8096887cbc9d9136698afc742c08e3d4a2c76681.

Certain types of network traffic are causing the unmaps in netback to
fail because the pages are in use.  We are not expecting these pages
to be in use here but it will take time to investigate why.
