we detect basically the cpu info before loading the microcode,
to be able to detect the vendor, and avoid any update on hypervisor.
I couldn't test because my cpu doesn't have any update available.

tested on Zen2 (Ryzen 3 5300U)
This support was submitted in October for inclusion in Linux.
Haiku supports only two profiles. We could probably add some more, and let the driver says which it supports.

* set PXN for all page tables below KERNEL_BASE
* also set PXN for physical page mapper
PXN, Privileged execute-never
When the PXN bit is 1, a Permission fault is generated if the processor
is executing at PL1 and attempts to execute an instruction fetched from
the corresponding memory region.

Use the Privileged Only Thread ID Register aka TPIDRPRW to store
the current thread pointer.
The Privileged Only Thread ID Register is only accessible
in privileged modes, and is read/write.

Set AP[2:0] and XN flags based on page attributes.
PXN is not implemented as it seems to be available only
in L1 descriptors on ARMv7.
Set TEX, B, C flags based on memoryType:
* B_MTR_UC is mapped to Strongly Ordered (TEX=0, B=0, C=0)
* B_MTR_WC is mapped to Shareable Device Memory (TEX=0, B=1, C=0)
* B_MTR_WT is mapped to Outer and Inner Write-Through, no Write-Allocate (TEX=0, B=0, C=1)
* B_MTR_WB is mapped to Outer and Inner Write-Back, no Write-Allocate (TEx=0, B=1, C=1)
* B_MTR_WP has no direct equivalent on the ARM so it's mapped as B_MTR_WB
* default is Write-Back
Implement ARMPagingMethod32Bit::AttributesToPageTableEntryFlags()
for mapping from page attributes to AP[2:0] and XN flags.
Implement ARMPagingMethod32Bit::PageTableEntryFlagsToAttributes()
for the reverse mapping used in Query() and QueryInterrupt()
i.e. recover page attributes from AP[2:0] and XN flags.
Implement ARMPagingMethod32Bit::MemoryTypeToPageTableEntryFlags()
fr mapping from memoryType to TEX, B, C flags.
Implement ARMVMTranslationMap32Bit::Protect() which used to be commented out.
Accessed and modified flags are not implemented yet, so no such
flags are returned from Query() and QueryInterrupt().
Also because of this, we just invalidate TLB on any call to Protect()
without checking whether the page has been accessed.

Bootloader:
* set permissions to kernel read/write, no user access
for initially mapped memory areas
* set permissions to kernel read/write, no execute,
no user access for UART
Kernel:
* physical memory mapper uses kernel read/write mapping
with no-execute bit enabled
* all other pages are mapped as read/write/execute for
kernel and user
* proper access permissions and memory types to be
implemented later
Enforce memory access permissions by setting DACR to
client mode for domain #0, no access for other domains.
see ARM Architecture Reference Manual, section B3.7 Memory access control
and in particular the following subsections:
B3.7.1 Access permissions
B3.7.2 Execute-never restrictions on instruction fetching
B3.7.3 Domains, Short-descriptor format only

For now this is used on RISCV64 to indicate that interrupts will always
be on CPU 0. However, in the future, some architectures may want
or require interrupts to be "steered" in various ways, and this
also paves the way for that.
