Now that all FGT fields are accounted for and represented, use
the generated value instead of manually specifying them.
For __HFGWTR_EL2_RES0, however, there is no generated value. Its
fields are subset of HFGRTR_EL2, with the remaining being RES0.
Therefore, add a mask that represents the HFGRTR_EL2 only bits
and define __HFGWTR_EL2_* using those and the __HFGRTR_EL2_*
fields.
No functional change intended.

These checks help ensure that all the bits are accounted for,
that there hasn't been a transcribing error from the spec nor
from the generated mask values, which will be used in subsequent
patches.

New trap bits have been defined since the latest update to this
patch. Moreover, the existing definitions of some of the mask
and the RES0 bits overlap, which could be wrong, confusing, or
both.
Update the bits based on DDI0601 2023-09, and ensure that the
existing bits are consistent.
Subsequent patches will use the generated RES0 fields instead of
specifying them manually. This patch keeps the manual encoding of
the bits to make it easier to review the series.

Add the encodings to fine grain trapping fields for HAFGRTR_EL2
and add the associated handling code in nested virt. Based on
DDI0601 2023-09. Add the missing field definitions as well,
both to generate the correct RES0 mask and to be able to toggle
their FGT bits.
Also add the code for handling FGT trapping, reading of the
register, to nested virt.

Do not rely on the value of __HFGRTR_EL2_nMASK to trap
unsupported features, since the nMASK can (and will) change as
new traps are added and as its value is updated. Instead,
explicitly specify the trap bits.

"This patchset fixes and enforces correct section alignments for the
ex_table, altinstructions, parisc_unwind, jump_table and bug_table

Due to not being correctly aligned at link & load time they can
trigger unnecessarily the kernel unaligned exception handler at
runtime. While at it, I switched the bug table to use relative
addresses which reduces the size of the table by half on 64-bit.
We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
from HP-UX, which now trigger build-issues with glibc. We can simply
remove them.

for the USB, PHY, and Thunderbolt driver subsystems. Include in here
are:
- reverts of some PHY drivers that went into 6.7-rc1 that shouldn't
have been merged yet, the author is reworking them based on review
comments as they were using older apis that shouldn't be used
anymore for newer drivers
- small thunderbolt driver fixes for reported issues
- USB driver fixes for a variety of small issues in dwc3, typec,
xhci, and other smaller drivers.
- new device ids for usb-serial and onboard_usb_hub drivers.
All of these have been in linux-next with no reported issues"

Pull xen fixes from Juergen Gross:

- A fix for the swiotlb-xen driver which was missing the advertising of
the maximum mapping length
- A fix for Xen on Arm for a longstanding bug, which happened to occur
only recently: a structure in percpu memory crossed a page boundary,
which was rejected by the hypervisor

arm/xen: fix xen_vcpu_info allocation alignment
xen: privcmd: Replace zero-length array with flex-array member and use __counted_by
swiotlb-xen: provide the "max_mapping_size" method
Enable GENERIC_BUG_RELATIVE_POINTERS which will store 32-bit relative
offsets to the bug address and the source file name instead of 64-bit
absolute addresses. This effectively reduces the size of the
bug_table[] array by half on 64-bit kernels.

Those return codes are only defined for the parisc architecture and
are leftovers from when we wanted to be HP-UX compatible.
They are not returned by any Linux kernel syscall but do trigger
problems with the glibc strerrorname_np() and strerror() functions as
reported in glibc issue #31080.
There is no need to keep them, so simply remove them.

Make sure that the __bug_table section gets 32- or 64-bit aligned,
depending if a 32- or 64-bit kernel is being built.
Mark it non-writeable and use .blockz instead of the .org assembler
directive to pad the struct.

On parisc we need 16-byte alignment for variables which are used for
locking. Mark the __lock_aligned attribute acordingly so that the
.data..lock_aligned section will get that alignment in the generated
object files.

The jump_table stores two 32-bit words and one 32- (on 32-bit kernel)
or one 64-bit word (on 64-bit kernel).
Ensure that the last word is always 64-bit aligned on a 64-bit kernel
by aligning the whole structure on sizeof(long).
