Pull irq fixes from Borislav Petkov:

 - Work around an erratum on GIC700, where a race between a CPU handling
   a wake-up interrupt, a change of affinity, and another CPU going to
   sleep can result in a lack of wake-up event on the next interrupt

 - Fix the locking required on a VPE for GICv4

 - Enable Rockchip 3588001 erratum workaround for RK3588S

 - Fix the irq-bcm6345-l1 assumtions of the boot CPU always be the first
   CPU in the system

 +Silicon Errata and Software Workarounds
 +=======================================
 +
 +Author: Will Deacon <will.deacon@arm.com>
 +
 +Date  : 27 November 2015
 +
 +It is an unfortunate fact of life that hardware is often produced with
 +so-called "errata", which can cause it to deviate from the architecture
 +under specific circumstances.  For hardware produced by ARM, these
 +errata are broadly classified into the following categories:
 +
 +  ==========  ========================================================
 +  Category A  A critical error without a viable workaround.
 +  Category B  A significant or critical error with an acceptable
 +              workaround.
 +  Category C  A minor error that is not expected to occur under normal
 +              operation.
 +  ==========  ========================================================
 +
 +For more information, consult one of the "Software Developers Errata
 +Notice" documents available on infocenter.arm.com (registration
 +required).
 +
 +As far as Linux is concerned, Category B errata may require some special
 +treatment in the operating system. For example, avoiding a particular
 +sequence of code, or configuring the processor in a particular way. A
 +less common situation may require similar actions in order to declassify
 +a Category A erratum into a Category C erratum. These are collectively
 +known as "software workarounds" and are only required in the minority of
 +cases (e.g. those cases that both require a non-secure workaround *and*
 +can be triggered by Linux).
 +
 +For software workarounds that may adversely impact systems unaffected by
 +the erratum in question, a Kconfig entry is added under "Kernel
 +Features" -> "ARM errata workarounds via the alternatives framework".
 +These are enabled by default and patched in at runtime when an affected
 +CPU is detected. For less-intrusive workarounds, a Kconfig option is not
 +available and the code is structured (preferably with a comment) in such
 +a way that the erratum will not be hit.
 +
 +This approach can make it slightly onerous to determine exactly which
 +errata are worked around in an arbitrary kernel source tree, so this
 +file acts as a registry of software workarounds in the Linux Kernel and
 +will be updated when new workarounds are committed and backported to
 +stable kernels.
