config CEPH_LIB

	depends on INET

	select CRYPTO_CBC
	select CRYPTO
	select KEYS
	default n
	help
	  Choose Y or M here to include cephlib, which provides the
	  common functionality to both the Ceph filesystem and
	  to the rados block device (rbd).

	  More information at http://ceph.newdream.net/.

	  If unsure, say N.

config CEPH_LIB_PRETTYDEBUG
	bool "Include file:line in ceph debug output"
	depends on CEPH_LIB
	default n
	help
	  If you say Y here, debug output will include a filename and
	  line to aid debugging.  This increases kernel size and slows
	  execution slightly when debug call sites are enabled (e.g.,
	  via CONFIG_DYNAMIC_DEBUG).

	  If unsure, say N.

config CEPH_LIB_USE_DNS_RESOLVER
	bool "Use in-kernel support for DNS lookup"
	depends on CEPH_LIB
	select DNS_RESOLVER
	default n
	help
	  If you say Y here, hostnames (e.g. monitor addresses) will
	  be resolved using the CONFIG_DNS_RESOLVER facility.

	  For information on how to use CONFIG_DNS_RESOLVER consult
	  Documentation/networking/dns_resolver.txt

	  If unsure, say N.

ass='commit-subject'>efi/fdt: Avoid FDT manipulation after ExitBootServices()
Some AArch64 UEFI implementations disable the MMU in ExitBootServices(), after which unaligned accesses to RAM are no longer supported. Commit: abfb7b686a3e ("efi/libstub/arm*: Pass latest memory map to the kernel") fixed an issue in the memory map handling of the stub FDT code, but inadvertently created an issue with such firmware, by moving some of the FDT manipulation to after the invocation of ExitBootServices(). Given that the stub's libfdt implementation uses the ordinary, accelerated string functions, which rely on hardware handling of unaligned accesses, manipulating the FDT with the MMU off may result in alignment faults. So fix the situation by moving the update_fdt_memmap() call into the callback function invoked by efi_exit_boot_services() right before it calls the ExitBootServices() UEFI service (which is arguably a better place for it anyway) Note that disabling the MMU in ExitBootServices() is not compliant with the UEFI spec, and carries great risk due to the fact that switching from cached to uncached memory accesses halfway through compiler generated code (i.e., involving a stack) can never be done in a way that is architecturally safe.
