Pristine 2.5.69 warnings for make defconfig

Pristine 2.5.69 warnings for make defconfig

[Riley Williams]

Hi all.

Using the pristine 2.5.69 source tree, there are several warnings generated
for `make defconfig ; make` which I am curious about. These are as follows:

 Q> kernel/ksyms.c:453: warning: `__check_region' is deprecated
 Q>				(declared at include/linux/ioport.h:113)

This corresponds to the line:

 453>	EXPORT_SYMBOL(__check_region);

Next, there is:

 Q> drivers/ide/ide-probe.c: In function `hwif_check_region':
 Q> drivers/ide/ide-probe.c:642: warning: `__check_region' is deprecated
 Q> 				(declared at include/linux/ioport.h:113)
 Q> drivers/ide/ide-probe.c:644: warning: `__check_region' is deprecated
 Q>				(declared at include/linux/ioport.h:113)

These correspond to the lines:

641>	if(hwif->mmio)
642>		err = check_mem_region(addr, num);
643>	else
644>		err = check_region(addr, num);

Next, there is:

 Q> drivers/pnp/resource.c: In function `pnp_check_port':
 Q> drivers/pnp/resource.c:298: warning: `__check_region' is deprecated
 Q>				(declared at include/linux/ioport.h:113)
 Q> drivers/pnp/resource.c: In function `pnp_check_mem':
 Q> drivers/pnp/resource.c:369: warning: `__check_region' is deprecated
 Q>				(declared at include/linux/ioport.h:113)

These correspond respectively to the lines:

298>	if (check_region(*port, length(port,end)))
 :
369>	if (__check_region(&iomem_resource, *addr, length(addr,end)))

I will also add that this "depreciated" function is found in the kernel
tree (after `make defconfig ; make` completes) as follows:

 Q> Binary file drivers/ide/ide-probe.o matches
 Q> Binary file drivers/ide/built-in.o matches
 Q> drivers/pnp/resource.c:369:
 Q> Binary file drivers/pnp/resource.o matches

 Q> System.map:13232:c0436524 r __ksymtab___check_region
 Q> System.map:15618:c043bd52 r __kstrtab___check_region

Next, there is:

 Q> include/asm/string.h:145: warning: `strchr' defined but not used

This corresponds to the lines:

144>	static inline char * strchr(const char * s, int c)
145>	{
146>	int d0;
147>	register char * __res;
148>	__asm__ __volatile__(
149>		"movb %%al,%%ah\n"
150>		"1:\tlodsb\n\t"
151>		"cmpb %%ah,%%al\n\t"
152>		"je 2f\n\t"
153>		"testb %%al,%%al\n\t"
154>		"jne 1b\n\t"
155>		"movl $1,%1\n"
156>		"2:\tmovl %1,%0\n\t"
157>		"decl %0"
158>		:"=a" (__res), "=&S" (d0) : "1" (s),"0" (c));
159>		return __res;
160>	}

Finally, there is:

 Q> drivers/scsi/qla1280.c:5948: warning:
 Q>		initialization from incompatible pointer type
 Q> drivers/scsi/qla1280.c:5948: warning:
 Q>		initialization from incompatible pointer type

These correspond to the line:

5948>	static Scsi_Host_Template driver_template = QLA1280_LINUX_TEMPLATE;	

Somebody will probably tell me that all of these are false positives,
but that doesn't worry me.

Best wishes from Riley.

Some modules still needs it - so it is exported.
People will ruin them out as time passes.

This I cannot explain - it should not happen. Oleg at some point asked
if this was a compiler bug. Anyone?

Which tell you that this driver is not converted to use the new error handling.
