====================
Dynamic LMTST region setup

This patch series allows RVU PF/VF to allocate memory for
LMTST operations instead of using memory reserved by firmware
which is mapped as device memory.
The LMTST mapping table contains the RVU PF/VF LMTST memory base
address entries. This table is used by hardware for LMTST operations.
Patch1 introduces new mailbox message to update the LMTST table with
the new allocated memory address.
====================

The current driver uses static LMTST region allocated by firmware.
This memory gets populated as PF/VF BAR2. RVU PF/VF driver ioremap
the memory as device memory for NIX/NPA operation. Since the memory
is mapped as device memory we see performance degration. To address
this issue this patch implements runtime memory allocation.
RVU PF/VF allocates memory during device probe and share the base
address with RVU AF. RVU AF then configure the LMT MAP table
accordingly.

This patch extends the lmtst_tbl_setup_req mbox to support run time
LMTST configuration.
RVU PF/VF and DPDK/ODP allocates a LMT region, creates a translation
entry for a device via VFIO IOCTLs.
This IOVA is shared with AF through above mbox. AF then uses
RVU_SMMU transulation Widget and gets PA for the IOVA and updates
the LMTtable entry for that device.

Introducing a new mailbox to support updating lmt entries
and common lmt base address scheme i.e. multiple pcifuncs
can share lmt region to reduce L1 cache pressure for application.
Parameters passed to mailbox includes the primary pcifunc
value whose lmt regions will be shared by other secondary
pcifuncs. Here secondary pcifunc will be the one who is
calling the mailbox.
For example:
By default each pcifunc has its own LMT base address:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR B
        PCIFUNC3    LMT_BASE_ADDR C
        PCIFUNC4    LMT_BASE_ADDR D
Application will choose PCIFUNC1 as base/primary pcifunc
and as and when other pcifunc(secondary pcifuncs) gets
probed, this mailbox will be called and LMTST table will
be updated as:
        PCIFUNC1    LMT_BASE_ADDR A
        PCIFUNC2    LMT_BASE_ADDR A
        PCIFUNC3    LMT_BASE_ADDR A
        PCIFUNC4    LMT_BASE_ADDR A

On FLR lmtst map table gets resetted to the default lmt
base addresses for all secondary pcifuncs.

Merge tag 'fs.openat2.unknown_flags.v5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux

Pull openat2 fixes from Christian Brauner:

 - Remove the unused VALID_UPGRADE_FLAGS define we carried from an
   extension to openat2() that we haven't merged. Aleksa might be
   getting back to it at some point but just not right now.

 - openat2() used to accidently ignore unknown flag values in the upper
   32 bits.

   The new openat2() syscall verifies that no unknown O-flag values are
   set and returns an error to userspace if they are while the older
   open syscalls like open() and openat() simply ignore unknown flag
   values:

      #define O_FLAG_CURRENTLY_INVALID (1 << 31)
      struct open_how how = {
            .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID,
            .resolve = 0,
      };

      /* fails */
      fd = openat2(-EBADF, "/dev/null", &how, sizeof(how));

      /* succeeds */
      fd = openat(-EBADF, "/dev/null", O_RDONLY | O_FLAG_CURRENTLY_INVALID);

   However, openat2() silently truncates the upper 32 bits meaning:

      #define O_FLAG_CURRENTLY_INVALID_LOWER32 (1 << 31)
      #define O_FLAG_CURRENTLY_INVALID_UPPER32 (1 << 40)

      struct open_how how_lowe32 = {
            .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_LOWER32,
      };

      struct open_how how_upper32 = {
            .flags = O_RDONLY | O_FLAG_CURRENTLY_INVALID_UPPER32,
      };

      /* fails */
      fd = openat2(-EBADF, "/dev/null", &how_lower32, sizeof(how_lower32));

      /* succeeds */
      fd = openat2(-EBADF, "/dev/null", &how_upper32, sizeof(how_upper32));

   Fix this by preventing the immediate truncation in build_open_flags()
   and add a compile-time check to catch when we add flags in the upper
   32 bit range.

fw_cfg_showrev() is called by an indirect call in kobj_attr_show(),
which violates clang's CFI checking because fw_cfg_showrev()'s second
parameter is 'struct attribute', whereas the ->show() member of 'struct
kobj_structure' expects the second parameter to be of type 'struct
kobj_attribute'.

$ cat /sys/firmware/qemu_fw_cfg/rev
3

$ dmesg | grep "CFI failure"
[   26.016832] CFI failure (target: fw_cfg_showrev+0x0/0x8):

Fix this by converting fw_cfg_rev_attr to 'struct kobj_attribute' where
this would have been caught automatically by the incompatible pointer
types compiler warning. Update fw_cfg_showrev() accordingly.
