Linus Torvalds 27b5d61c0c A fix and an email address update: ... - Prevent FPU state corruption. The condition in irq_fpu_usable() grants FPU usage when the FPU is not used in the kernel. That's just wrong as it does not take the fpregs_lock()'ed regions into account. If FPU usage happens within such a region from interrupt context, then the FPU state gets corrupted. That's a long standing bug, which got unearthed by the recent changes to the random code. - Josh wants to use his kernel.org email address -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmJ3sb0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoRR9EACOcJAkO4ZjHvQf8RDw4ZaC/d0PgEC1 rEcxL7Tq9qAjdY+VmoRdzAia1FbKWrSNzENiBaTwdM2dxsZN0cl5fEQAy5ffHKXr IadRIHICu6INKQ0iuf4VdOt8HuMC+Ams9sFoVDId1avRoejsjIHeCpgBen+0/LQf D4i+nvUL9hMcZDsWiQW9mTe8J4fqr7rrg+p7tD0300DbZ6/PFx+zWP58TE8K7vQ8 dsmfMXxDrJW3d9FOHHvPQXa/Okdm2fHxXuxs3Quc+7HG6cMcwefCYugf8HK3E14F q0O6IAOfiYzCL+8aNo4J3H5jPEGLMJ7JlY5Yoygc1mcx0uGyVraMbFOsK8WuRFvP eAmx31Wh6EIYOwaboSG+74k/b3hPa6Hx3R7aQDS+SnQQI6I9fdi3ZZtQ+DGnZBZG Ipq/f+EjaROh1atUwhE4zM80UKSU6RWEWAlMO4K07uO8a3RnR8qV7N8tl44i+Q7k KZUbN5/aV4ccZNwMbazcpZ32fe3SB9cD4e/aLqpMp0uOl9TVxcOA3hIkQ0wflh94 6XO+gPdvr5VxWayc9tljMXUGPxwjTN4zDKUIlZP2EzYHt6SyZpdwi2+8moEfvU+a qcIWPLeXb+972LaY+rTicT4cQxCKe0CZEXCOq1ns+Ni5f5TdKkvyxpeMIOrGtjYG /4RqWncPKIyuEw== =PpOB -----END PGP SIGNATURE----- Merge tag 'x86-urgent-2022-05-08' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 fix from Thomas Gleixner: "A fix and an email address update: - Prevent FPU state corruption.
