Hello,
I'm trying to build a 2.6.22.1-rt9 kernel for a P3.
I used 'make xconfig' to create .config
http://linux.kernel.free.fr/latency/config-2.6.22.1-rt9-adlink
I get the following warning:
LD vmlinux
SYSMAP System.map
SYSMAP .tmp_System.map
MODPOST vmlinux
WARNING: kernel/built-in.o(.text+0x19152): Section mismatch: reference
to .init.text: (between 'kthreadd' and 'init_waitqueue_head')

GZIP arch/i386/boot/compressed/vmlinux.bin.gz

OBJCOPY arch/i386/boot/vmlinux.bin
HOSTCC arch/i386/boot/tools/build
BUILD arch/i386/boot/bzImage
Root device is (3, 1)
Boot sector 512 bytes.
Setup is 7082 bytes.
System is 1142 kB
Kernel: arch/i386/boot/bzImage is ready (#1)
Building modules, stage 2.
MODPOST 0 modules
I also get the following warnings (which seem less severe)
CC drivers/pci/pci.o
CC drivers/pci/quirks.o
CC drivers/pci/pci-driver.o
CC drivers/pci/search.o
drivers/pci/search.c: In function `pci_find_slot':
drivers/pci/search.c:99: warning: `pci_find_device' is deprecated
(declared at include/linux/pci.h:477)
drivers/pci/search.c: At top level:
drivers/pci/search.c:434: warning: `pci_find_device' is deprecated
(declared at drivers/pci/search.c:241)
drivers/pci/search.c:434: warning: `pci_find_device' is deprecated
(declared at drivers/pci/search.c:241)
CC drivers/pci/pci-sysfs.o
CC drivers/pci/rom.o
Finally, I note that X86_CMPXCHG64 is no longer defined since its
specification was changed between 2.6.20 and 2.6.22.
config X86_CMPXCHG64
bool
- depends on !M386 && !M486
+ depends on X86_PAE
default y
Will this have an impact on spinlocks? RCU? something else?
Regards.

This is a bogus warning, already taken care of in 2.6.23-rc1-latestgit.

No idea about this one.

this patch resolve the warning ?
I always got this warning but don't care much about it
