floatunsidf and fixunsdfsi undefined

Dear all,
 I am trying to compile compat-wireless-3.2-rc6-3 on
a2.6.32-37-generic i686 GNU/Linux.
Everything goes well until I enter in phase 2, and I receive the
following WARNING which prevent the mac80211 modules to work properly
if installed

make -C /lib/modules/2.6.32-37-generic/build
M=/home/claudio/Programs/compat-wireless-3.2-rc6-3 modules

the first time I compiled and installed the compat-wireless-3.2-rc6-3
it worked, but now it is not.

My distribution (UBUNTU 10.04) already comes with ath9k and mac80211.

Could  somebody give me an hint? I am a newbie at this

Thank you

Claudio

[PATCH] mac80211: minstrel_ht: fix NULL pointer dereference during auth/assoc

This patch fixes the following NULL pointer dereference:

> minstrel_tx_status+0x48/0xe0 [mac80211]

static inline int
rix_to_ndx(struct minstrel_sta_info *mi, int rix)
{
        int i = rix;
        for (i = rix; i >= 0; i--)
                if (mi->r[i].rix == rix)
  48:   3b 58 04                cmp    0x4(%eax),%ebx
  4b:   74 4b                   je     98 <minstrel_tx_status+0x98>
  4d:   83 c2 01                add    $0x1,%edx

It fails because of mi->r[i] being a NULL pointer. It is allocated in
minstel_alloc_sta, but minstrel_ht_alloc_sta does not call that function.

struct minstrel_ht_sta_priv holds a union with struct minstrel_ht_sta and
struct minstrel_sta_info. During authenticate the bool is_ht is false so
minstrel_ht_tx_status calls minstrel_tx_status, but minstrel_sta_info::r
is not set until rate_init which is after assoc.
