Subject: [PATCH v6 0/8] ARM vmap'ed and IRQ stacks roundup
Date: Tue, 25 Jan 2022 10:14:45 +0100 [thread overview]
Message-ID: <20220125091453.1475246-1-ardb@kernel.org> (raw)
This v6 series is a followup to [0], and presents the proposed changes
as a set of delta patches against the v4 that was already taken into
rmk/devel-stable, and dropped from v5.17 when it turned out that were
unresolved issues related to suspend/resume.
These patches apply onto rmk/devel-stable directly, which means there is
an unresolved conflict with the changes that landed in v5.17-rc1 via the
ARM tree: these will need to be handled by the maintainer.
Code can be found under the arm-vmap-stacks-v6 tag at
git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux.git

Ard Biesheuvel (8):
ARM: mm: switch to swapper_pg_dir early for vmap'ed stack
ARM: assembler: define a Kconfig symbol for group relocation support
ARM: smp: elide HWCAP_TLS checks or __entry_task updates on SMP+v6
ARM: entry: avoid clobbering R9 in IRQ handler
ARM: mm: make vmalloc_seq handling SMP safe
ARM: iop: make iop_handle_irq() static
ARM: drop pointless SMP check on secondary startup path
ARM: make get_current() and __my_cpu_offset() __always_inline
