When I replaced hugetlb_dynamic_pool with nr_overcommit_hugepages I used
proc_doulongvec_minmax() directly. However, hugetlb.c's locking rules
require that all counter modifications occur under the hugetlb_lock. Add a
callback into the hugetlb code similar to the one for nr_hugepages. Grab
the lock around the manipulation of nr_overcommit_hugepages in
proc_doulongvec_minmax().

Move Orion virtual mappings higher up in the address space, to free
up more kernel virtual address space.

Hack up the Orion port to distinguish between virtual and physical
addresses of register windows. This will allow moving virtual
mappings higher up in the address space, to free up more kernel
virtual address space.

This patch contain the core infrastructure of enhanced partition
statistics. It adds to struct hd_struct the same stats data as struct
gendisk and define basics function to manipulate them.

Rearrange fields in cache order and initialize some fields that
we didn't previously init. Remove init of ->completion_data, it's
part of a union with ->hash. Luckily clearing the rb node is the same
as setting it to null!

- Add ifdef around macros to read and write hardware registers
- Add parens around REG_READ expression to avoid possible precedence errors.
- Remove useless CVS id tag.
- A couple of fields have changed name:
reg_eth_rw_ga_lo.table -> tbl
reg_eth_rw_ga_hi.table -> tbl
reg_eth_rw_gen_ctrl.flow_ctrl_dis -> flow_ctrl
- Add some new register fields.
reg_eth_rw_gen_ctrl.gtxclk_out
reg_eth_rw_gen_ctrl.phyrst_n
reg_eth_rw_tr_ctrl.carrier_ext
- max_size in reg_eth_rw_rec_ctrl had the wrong size.
- Registers reg_eth_rw_mgm_ctrl and reg_eth_r_stat was reworked completely.
The old name "r" would quite often produce warnings when other
variables with the same name was shadowed. Rename it __x to
make it more unlikely to happen.
- Shorten include paths for machine dependent header files.
- Add volatile to hardeware register pointers.
- Add spinlocks around critical region.
- Expand macros for handling of leds.
- Add partition table struct to be used to parse partition table in flash.
- Add JFFS2 as a type, and add readoly flag.
- Improve some comments.
- Lindent has been run, fixing whitespace and formatting issues.
The header files describe the hardware registers available in both
these chips, note that most of this documentation is automatically
generated from the hardware implementation.
