[PATCH 1/1] x86/hyperv: Disable IBT when hypercall page lacks ENDBR instruction

by Michael Kelley

On hardware that supports Indirect Branch Tracking (IBT), Hyper-V VMs with ConfigVersion 9.3 or later support IBT in the guest. However, current versions of Hyper-V have a bug in that there's not an ENDBR64 instruction at the beginning of the hypercall page. Since hypercalls are made with an indirect call to the hypercall page, all hypercall attempts fail with an exception and Linux panics. A Hyper-V fix is in progress to add ENDBR64. But guard against the Linux panic by clearing X86_FEATURE_IBT if the hypercall page doesn't start with ENDBR. The VM will boot and run without IBT. If future Linux 32-bit kernels were to support IBT, additional hypercall page hackery would be needed to make IBT work for such kernels in a Hyper-V VM.

[RESEND PATCH v8 07/10] serial: sc16is7xx: fix bug when first setting GPIO direction

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> When configuring a pin as an output pin with a value of logic 0, we end up as having a value of logic 1 on the output pin. Setting a logic 0 a second time (or more) after that will correctly output a logic 0 on the output pin. By default, all GPIO pins are configured as inputs. When we enter sc16is7xx_gpio_direction_output() for the first time, we first set the desired value in IOSTATE, and then we configure the pin as an output. The datasheet states that writing to IOSTATE register will trigger a transfer of the value to the I/O pin configured as output, so if the pin is configured as an input, nothing will be transferred. Therefore, set the direction first in IODIR, and then set the desired value in IOSTATE. This is what is done in NXP application note AN10587.

[RESEND PATCH v8 02/10] serial: sc16is7xx: mark IOCONTROL register as volatile

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> Bit SRESET (3) is cleared when a reset operation is completed. Having the IOCONTROL register as non-volatile will always read SRESET as 1, which is incorrect. Also, if IOCONTROL register is not a volatile register, the upcoming patch "serial: sc16is7xx: fix regression with GPIO configuration" doesn't work when setting some shared GPIO lines as modem control lines. Therefore mark IOCONTROL register as a volatile register.
