Linus Torvalds 6ebb6814a1 Two perf fixes: ... - Do not check the LBR_TOS MSR when setting up unrelated LBR MSRs as this can cause malfunction when TOS is not supported. - Allocate the LBR XSAVE buffers along with the DS buffers upfront because allocating them when adding an event can deadlock. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmCqWZQTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoZe6D/9vKZRfmbdvOwfE0Z7dBil2dyBoqYHw yTfnGs0pNpmj2mY7ZPig3gmXnryt4cwMcTtVJZFdmYJBBS28tqGeJb7eMIxtSqAu aBChANXVOnbAS8vXe555nS/BVxEtfkIBgOLyYlD0hE4PIZpBbqTzhxj4daLTk4bg h4hyIzDMBs+4tLupVhOahg6ZaHd97S61e7gBR9I5D7tHAUMo8Ea0ChQD5p2kDYI5 leKroBnjUFMP0o2DYPUR+6Zma50JQ29QK1u34q4mx0IhIdgqtNs8eZE/kYUu2FSZ Nf4GG2ALzxWjXniqRPrXbkP/ScrwVdhg7ULOG34aNT1Jx04KaMSkav93gbOdozV9 IYvf99zwptD3g9W4yDveWjGrhEoxiARI4VUQJBnIbQP9rZ2YIRwOHIXwux1AxWQh ok6CP94m16AWp0wbm9HRJS80MUv1zHPK5oW3B1vkchxHihkV4XdoP6vny03Z2FcC elMgFquDxP4l5i3ao0Ryn4YaCAFc3MiWvw3x4YXpv9dCE6Al+iKdclkYPJgrYWYE wUN8jdODfIyBIOI94GnwYl5rHIoS2fH8LSpP36gIX7DMKPh5y7184jUQWjHTN6PT /D94us3m8Cvq+sfZrhGDHPY4BEaYeczTo6vbVoN4iBthElLYRkHp7lc7gcDpsU8B dzHcwyMFQAnKLQ== =7WGT -----END PGP SIGNATURE----- Merge tag 'perf-urgent-2021-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull perf fixes from Thomas Gleixner: "Two perf fixes: - Do not check the LBR_TOS MSR when setting up unrelated LBR MSRs as this can cause malfunction when TOS is not supported - Allocate the LBR XSAVE buffers along with the DS buffers upfront because allocating them when adding an event can deadlock" * tag 'perf-urgent-2021-05-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/lbr: Remove cpuc->lbr_xsave allocation from atomic context perf/x86: Avoid touching LBR_TOS MSR for Arch LBR		2021-05-23 06:32:40 -10:00
