Attached are two small patches for include/net/ieee80211.h to prepare
for later submission of code to implement a user-space daemon that
supplies 802.11 regulatory information.
The first change adds a bit indicating that 802.11h rules are to be
applied to a channel. As discussed earlier in this list, a single bit
is unlikely to be sufficient; however, at this time I have been unable
to find any regulations implementing differences between 802.11a and
802.11h other than DFS, radar detection and passive scanning. A single
bit is thus sufficient to convey to the driver that these rules should
be obeyed.
The second change adds comments to the freq and max_power fields of
struct ieee80211_channel to indicate the units that are used.

Make HZ configurable. DECSTATION can select 128/256/1024 HZ, JAZZ can
only select 100 HZ, others can select 100/128/250/256/1000/1024 HZ if
not explicitly specified). Also remove all mach-xxx/param.h files and
update all defconfigs according to current HZ value.

Keeping in accordance with other machines, IP27 and IP32 lack a few

Historically plat_mem_setup did the entire platform initialization. This
was rather impractical because it meant plat_mem_setup had to get away
without any kind of memory allocator. To keep old code from breaking
plat_setup was just renamed to plat_setup and a second platform
initialization hook for anything else was introduced.

kern_addr_valid is currently only being used in kmem_ptr_validate which
is making some vague attempt at verfying the validity of an address.
Only IA-64, PARISC and x86-64 actually make some actual effort to verify
the validity of the pointer. Most architecture definitions of
kern_addr_valid() just define it as 1; the Alpha and CONFIG_DISCONTIGMEM
on i386 and MIPS even as 0; the 0-definition will result in
kmem_ptr_validate always failing which in turn will cause d_validate to
always fail. d_validate's only two users are smbfs and ncpfs, so the
0 definition ended breaking those ...

I found that NPTL's pthread_cond_signal() does not work properly on
kernels compiled by gcc 4.1.x. I suppose inline asm for
__futex_atomic_op() was wrong. I suppose:
1. "=&r" constraint should be used for oldval.
2. Instead of "r" (uaddr), "=R" (*uaddr) for output and "R" (*uaddr)
for input should be used.
3. "memory" should be added to the clobber list.

Currently, all userspace verbs operations that call into the kernel
are serialized by ib_uverbs_idr_mutex. This can be a scalability
issue for some workloads, especially for devices driven by the ipath
driver, which needs to call into the kernel even for datapath
operations.
Fix this by adding reference counts to the userspace objects, and then
converting ib_uverbs_idr_mutex into a spinlock that only protects the
idrs long enough to take a reference on the object being looked up.
Because remove operations may fail, we have to do a slightly funky
two-step deletion, which is described in the comments at the top of
uverbs_cmd.c.
This also still leaves ib_uverbs_idr_lock as a single lock that is
possibly subject to contention. However, the lock hold time will only
be a single idr operation, so multiple threads should still be able to
make progress, even if ib_uverbs_idr_lock is being ping-ponged.
Surprisingly, these changes even shrink the object code:
add/remove: 23/5 grow/shrink: 4/21 up/down: 633/-693 (-60)
