crypto: remove obsolete 'comp' compression API

The 'comp' compression API has been superseded by the acomp API, which
is a bit more cumbersome to use, but ultimately more flexible when it
comes to hardware implementations.

Now that all the users and implementations have been removed, let's
remove the core plumbing of the 'comp' API as well.

crypto: fips - Move fips_enabled sysctl into fips.c

There is currently a large ifdef FIPS code section in proc.c.
Ostensibly it's there because the fips_enabled sysctl sits under

In fact, the whole ethos of the crypto API is against such user
interfaces so this patch moves all the FIPS sysctl code over to
fips.c.

This patch makes /proc/crypto call the type-specific show function
if one is present before calling the legacy show functions for
cipher/digest/compress. This allows us to reuse the type values
for those legacy types. In particular, hash and digest will share
one type value while shash is phased in as the default hash type.

Add the ability to turn FIPS-compliant mode on or off at boot

In order to be FIPS compliant, several check may need to be preformed that may
be construed as unusefull in a non-compliant mode. This patch allows us to set
a kernel flag incating that we are running in a fips-compliant mode from boot
up. It also exports that mode information to user space via a sysctl
(/proc/sys/crypto/fips_enabled).

Tested successfully by me.

The crypto API is made up of the part facing users such as IPsec and the

This patch splits out the latter so that the two APIs are more clearly
delineated. As a bonus the low-level API can now be modularised if all
algorithms are built as modules.
