Building kernel using toolchain build with sanitized headers

[Dan Kegel <dank at kegel dot com>]

This is just a note to myself, really.
I'm sure these issues are my own fault somehow.

I tried building with sanitized headers today, and ran into
curious problems on the following combinations, all using
gcc-3.4.3, glibc-2.3.5, binutils-2.15, linux-2.6.8 (or 2.6.11.3),
and  linux-libc-headers-2.6.11.2:

alpha-gcc-3.4.3-glibc-2.3.5
arm-gcc-3.4.3-glibc-2.3.5
ia64-gcc-3.4.3-glibc-2.3.5

Here are the errors:

--- alpha ---
arch/alpha/kernel/sys_titan.c:204: warning: initialization from incompatible pointer type
make[1]: *** [arch/alpha/kernel/sys_titan.o] Error 1

For alpha, the error was probably a mismatch between
include/linux/irq.h:    void (*set_affinity)(unsigned int irq, cpumask_t dest);
and
arch/alpha/kernel/sys_titan.c: static void titan_set_irq_affinity(unsigned int irq, unsigned long affinity)

(Hmm.  That just seems like a bug?)

Hrm.  It's unhappy that CONFIG_CPU_ABRT_* weren't defined.

--- ia64 ---

arch/ia64/kernel/acpi.c: In function `acpi_get_sysname':
arch/ia64/kernel/acpi.c:77: warning: implicit declaration of function `acpi_find_rsdp'
arch/ia64/kernel/acpi.c:84: error: dereferencing pointer to incomplete type
arch/ia64/kernel/acpi.c:89: error: dereferencing pointer to incomplete type

make[1]: *** [arch/ia64/kernel/acpi.o] Error 1
make: *** [arch/ia64/kernel] Error 2

For ia64, the incomplete types were probably
struct acpi20_table_rsdp
and
struct acpi_table_xsdt
