Updates for IRQ stacks and virtually mapped stack support for ARM from the following pull requests, etc: 1) ARM: support for IRQ and vmap'ed stacks This PR covers all the work related to implementing IRQ stacks and vmap'ed stacks for all 32-bit ARM systems that are currently supported by the Linux kernel, including RiscPC and Footbridge. It has been submitted for review in three different waves: - IRQ stacks support for v7 SMP systems [0], - vmap'ed stacks support for v7 SMP systems[1], - extending support for both IRQ stacks and vmap'ed stacks for all remaining configurations, including v6/v7 SMP multiplatform kernels and uniprocessor configurations including v7-M [2] [0] https://lore.kernel.org/linux-arm-kernel/20211115084732.3704393-1-ardb@kernel.org/ [1] https://lore.kernel.org/linux-arm-kernel/20211122092816.2865873-1-ardb@kernel.org/ [2] https://lore.kernel.org/linux-arm-kernel/20211206164659.1495084-1-ardb@kernel.org/ 2) ARM: support for IRQ and vmap'ed stacks [v6] This tag covers the changes between the version of vmap'ed + IRQ stacks support pulled into rmk/devel-stable [0] (which was dropped from v5.17 due to issues discovered too late in the cycle), and my v5 proposed for the v5.18 cycle [1].
