This is because asm-generic/io.h defines # PCI_IOBASE, which results in the function acpi_pci_root_remap_iospace() # doing a lot of unnecessary (and wrong) things. # # I'd suggested an #if !CONFIG_IA64 in the functon, but Arnd suggested # keeping the fix inside the arch/ia64 tree. # # Fixes: 0bbf47eab469 ("ia64: use asm-generic/io.h") # Suggested-by: Arnd Bergman <arnd@arndb.de> # Signed-off-by: Tony Luck <tony.luck@intel.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < git log --format=%s --max-count=1 cc26ebbebde8548014d9329ac2f6cf0178181789 # < make -s -j 48 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- x86_64_defconfig # make -s -j 48 ARCH=x86 O=/kisskb/build/linus_x86_64_defconfig_x86_64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:183:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/cgroup/cgroup-v1.c: In function 'cgroup1_mount': /kisskb/src/kernel/cgroup/cgroup-v1.c:1256:20: warning: 'root' may be used uninitialized in this function [-Wuninitialized] kernel/rcu/tree.o: warning: objtool: rcu_init()+0x1c5: unreachable instruction /kisskb/src/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1034:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/vmstat.c: In function 'sysctl_vm_numa_stat_handler': /kisskb/src/mm/vmstat.c:89:5: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] kernel/trace/trace.o: warning: objtool: tracing_start()+0x6d: unreachable instruction /kisskb/src/sound/hda/hdac_regmap.c: In function 'hda_reg_write': /kisskb/src/sound/hda/hdac_regmap.c:282:16: warning: 'err' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:653:2: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1433:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2511:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1833:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:339:21: note: 'pdeo' was declared here drivers/clk/clk.o: warning: objtool: clk_prepare_unlock()+0x44: unreachable instruction /kisskb/src/drivers/dma-buf/reservation.c: In function 'reservation_object_add_shared_fence': /kisskb/src/drivers/dma-buf/reservation.c:208:2: warning: 'k' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/dma-buf/reservation.c:161:17: note: 'k' was declared here /kisskb/src/drivers/gpu/drm/i915/i915_irq.c: In function 'gen11_irq_handler': /kisskb/src/drivers/gpu/drm/i915/i915_irq.c:3120:10: warning: 'gu_misc_iir' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/gpu/drm/i915/i915_irq.c:3131:6: note: 'gu_misc_iir' was declared here fs/aio.o: warning: objtool: aio_nr_sub()+0x2d: unreachable instruction /kisskb/src/net/mac80211/mlme.c: In function 'ieee80211_rx_mgmt_beacon': /kisskb/src/net/mac80211/mlme.c:1448:3: warning: 'pwr_level_cisco' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/mac80211/mlme.c:1405:6: note: 'pwr_level_cisco' was declared here Completed OK # rm -rf /kisskb/build/linus_x86_64_defconfig_x86_64 # Build took: 0:01:23.366396
