Create std.arm and std.armv6 config files and include the right one from each of the existing kernel configs. This gives a place to put config that applies to the entire arch. Add the ARM_NEW_PMAP option to std.armv6. This is working well in early testing and it's time for wide exposure, but it's still nice to be able to fall back to the old implementation for testing when a problem comes along. Eventually the option and the old implementation will go away. The opportunity now exists to move a whole lot of boilerplate from all the arm kernel config files into std.arm*, but that's a commit for another day.

Remove HZ=<various> from all armv6 configs, put HZ=1000 in std.armv6. All armv6 processors are plenty fast enough for HZ=1000. No changes are made for older arm systems, because some chips are a bit wimpy for 1000 while others do fine, so it has to be set on a per-config basis.

Move ARM_L2_PIPT option to std.armv6 for all armv6 platforms. Only L2 PIPT cache is supported for __ARM_ARCH >= 6. In fact, this is just a pure proclamation as this option is used only in armv4 specific files now.

In the TCP stack, the hhook(9) framework provides hooks for kernel modules to add actions that run when a TCP frame is sent or received on a TCP session in the ESTABLISHED state. In the base tree, this functionality is only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd, and cc_vegas congestion control modules. Presently, we incur overhead to check for hooks each time a TCP frame is sent or received on an ESTABLISHED TCP session. This change adds a new compile-time option (TCP_HHOOK) to determine whether to include the hhook(9) framework for TCP. To retain backwards compatibility, I added the TCP_HHOOK option to every configuration file that already defined "options INET". (Therefore, this patch introduces no functional change. In order to see a functional difference, you need to compile a custom kernel without the TCP_HHOOK option.) This change will allow users to easily exclude this functionality from their kernel, should they wish to do so. Note that any users who use a custom kernel configuration and use one of the congestion control modules listed above will need to add the TCP_HHOOK option to their kernel configuration.
