Hallo l-k,

I'm beginner in the kernel hacking (or fixing ;-))).

I have small patch, which is fixing some compilation errors (I'm using
gcc-2.95.4-17 from Debian sid).

The first chunk fixed this warning:

arch/i386/kernel/irq.c: In function `do_IRQ':
arch/i386/kernel/irq.c:331: warning: unused variable `esp'

I move declaration of variable esp to the #ifdef blok, where it is
using...

The second chunk fixed this warning:

In file included from arch/i386/kernel/timers/timer_pit.c:15:
arch/i386/mach-generic/do_timer.h: In function `do_timer_interrupt_hook':
arch/i386/mach-generic/do_timer.h:26: warning: implicit declaration of
function `smp_local_timer_interrupt'

I've found, that declaration of function do_timer_interrupt_hook is in
the header asm/apic.h and it is as:

extern void do_timer_interrupt_hook...

Then I add #include of asm/apic.h

The third chunk fixed this error:

net/ipv4/raw.c: In function `raw_send_hdrinc':
net/ipv4/raw.c:297: `NF_IP_LOCAL_OUT' undeclared (first use in this
function)
net/ipv4/raw.c:297: (Each undeclared identifier is reported only once
net/ipv4/raw.c:297: for each function it appears in.)

In this case was missing #include of netfilter_ipv4.h...

Any comments and sugestion is welcome...

Sincerely
Jan Marek
