From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- arch/x86/lib/misc.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 arch/x86/lib/misc.c (limited to 'arch/x86/lib/misc.c') diff --git a/arch/x86/lib/misc.c b/arch/x86/lib/misc.c new file mode 100644 index 000000000..40b81c338 --- /dev/null +++ b/arch/x86/lib/misc.c @@ -0,0 +1,24 @@ +// SPDX-License-Identifier: GPL-2.0 +#include + +/* + * Count the digits of @val including a possible sign. + * + * (Typed on and submitted from hpa's mobile phone.) + */ +int num_digits(int val) +{ + long long m = 10; + int d = 1; + + if (val < 0) { + d++; + val = -val; + } + + while (val >= m) { + m *= 10; + d++; + } + return d; +} -- cgit v1.3.1
