Hi,
just tried to ALSA 0.9.0rc8b on a stock-Redhat 8.0 with redhat kernel 2.4.18-14. I got
a
series of similar warnings:
...
In file included from /root/alsa-driver-0.9.0rc8b/include/sound/driver.h:43,
from ../../alsa-kernel/core/ioctl32/ioctl32.c:21,

/root/alsa-driver-0.9.0rc8b/include/adriver.h:325:1: warning: "vmalloc_to_page"

...
I saw that the patch suggested by Takashi (see below) was integrated in 0.9.0rc8b -
but I
guess it doesn't apply to my 2.4.18 kernel, because when I changed it, compilation went
through fine:
alsa-driver/include/adriver.h:322
/* vmalloc_to_page wrapper */
- #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 4, 19)
+ #if LINUX_VERSION_CODE < KERNEL_VERSION(2, 4, 18)
struct page *snd_compat_vmalloc_to_page(void *addr);
#define vmalloc_to_page(addr) snd_compat_vmalloc_to_page(addr)
#endif
and analogous changes in
alsa-driver/acore/memory_wrapper.c
alsa-driver/acore/memalloc.c.
Maybe you should verify in which kernel version this modification was actually made to
the
vmalloc thing...
