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> Binary file drivers/pnp/built-in.o matches Q> Binary file drivers/built-in.o matches Q> include/linux/ioport.h:108: Q> include/linux/ioport.h:110: Q> include/linux/ioport.h:113: Q> Binary file arch/i386/boot/compressed/vmlinux.bin matches Q> kernel/ksyms.c:453: Q> kernel/resource.c:304: Q> Binary file kernel/resource.o matches Q> Binary file kernel/ksyms.o matches Q> Binary file kernel/built-in.o matches Q> Binary file .tmp_vmlinux1 matches Q> Binary file .tmp_vmlinux2 matches Q> Binary file vmlinux matches Q> System.map:716:c0122a5f T __check_region 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.
