Commitbd82d4bd21("arm64: Fix incorrect irqflag restore for priority masking") added a macro to the entry.S call paths that leave the PSTATE.I bit set. This tells the pPNMI masking logic that interrupts are masked by the CPU, not by the PMR. This value is read back by local_daif_save(). Commitbd82d4bd21added this call to el0_svc, as el0_svc_handler is called with interrupts masked. el0_svc_compat was missed, but should be covered in the same way as both of these paths end up in el0_svc_common(), which expects to unmask interrupts.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
