Hi All,
I have a doubt, the MSI domains are handled differently in different RC
drivers.
Some drivers use irq_domain_add_linear alone, and some use
pci_msi_create_irq_domain also to handle MSI.
In most of the 32-bit architectures only irq_domain_add_linear is used
and in 64 bit drivers bot

If we happen to receive interrupts during hv_set_host_time() execution
our adjustments may get inaccurate. Make the whole function atomic.
Unfortunately, we can's call do_settimeofday64() with interrupts
disabled as some cross-CPU work is being done but this call happens
very rarely.

From: Mark Rutland
Any fields not defined in an arm64_ftr_bits entry are propagated to the
system-wide register value in init_cpu_ftr_reg(), and while we require
that these strictly match for the sanity checks, we don't update them in
update_cpu_ftr_reg().
Generally, the lack of an arm64_ftr_bit
Track the user visible fields of a CPU feature register. This will be
used for exposing the value to the userspace. All the user visible

This series adds a new ABI to expose the CPU feature registers
to the user space via emulation of MRS instruction. The system exposes
only a limited set of feature values (See the documentation patch)
from the cpufeature infrastructure. The feature bits that are not
exposed are set to the 'safe val

This patch adds the hook for emulating MRS instruction to
export the 'user visible' value of supported system registers.
We emulate only the following id space for system registers:
Op0=3, Op1=0, CRn=0, CRm=[0, 4-7]
The rest will fall back to SIGILL. This capability is also
advertised via a new
This patch does the following clean ups :
1) All undescribed fields of a register are now treated as "strict"
with a safe value of 0. Hence we could leave an empty table for
describing registers which are RAZ.
2) ID_AA64DFR1_EL1 is RAZ and should use the table for RAZ register.
3) ftr_gene
From: Mark Rutland
We currently have some RAZ fields described explicitly in our
arm64_ftr_bits arrays. These are inconsistently commented, grouped,
and/or applied, and maintaining these is error-prone.
Luckily, we don't need these at all. We'll never need to inspect RAZ
fields to determine feat
