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 --- include/asm-generic/simd.h | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) create mode 100644 include/asm-generic/simd.h (limited to 'include/asm-generic/simd.h') diff --git a/include/asm-generic/simd.h b/include/asm-generic/simd.h new file mode 100644 index 000000000..70c8716ad --- /dev/null +++ b/include/asm-generic/simd.h @@ -0,0 +1,22 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _ASM_GENERIC_SIMD_H +#define _ASM_GENERIC_SIMD_H + +#include +#include +#include +#include + +/* + * may_use_simd - whether it is allowable at this time to issue SIMD + * instructions or access the SIMD register file + * + * As architectures typically don't preserve the SIMD register file when + * taking an interrupt, !in_interrupt() should be a reasonable default. + */ +static __must_check inline bool may_use_simd(void) +{ + return !in_interrupt(); +} + +#endif /* _ASM_GENERIC_SIMD_H */ -- cgit v1.3.1
