Subjectlinux-next: build failure after merge of the final tree (wireless tree related)
Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/net/wireless/rtlwifi/rtl8192cu/sw.c: In function 'rtl92cu_init_sw_vars':
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c:60: error: implicit declaration of function 'vmalloc'
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c:60: warning: assignment makes pointer from integer without a cast
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c: In function 'rtl92cu_deinit_sw_vars':
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c:74: error: implicit declaration of function 'vfree'

Caused by commit 442888c706e90634c4cc3441751b43115a7d8506 ("rtlwifi:
rtl8192cu: Add routines dm, fw, led and sw"). Missing an include of
linux/vmalloc.h. See Rule 1 in Documentation/SubmitChecklist.

I added the following patch:

but then got:

and lots more.

So I have used the wireless tree from next-20110221 for today.
