Starting with kernel 6.7, the framebuffer text console is not working
anymore with the virtio-gpu device on s390x hosts. Such big endian fb
devices are usinga different pixel ordering than little endian devices,
e.g. DRM_FORMAT_BGRX8888 instead of DRM_FORMAT_XRGB8888.
This used to work fine as long as drm_client_buffer_addfb() was still
calling drm_mode_addfb() which called drm_driver_legacy_fb_format()
internally to get the right format. But drm_client_buffer_addfb() has
recently been reworked to call drm_mode_addfb2() instead with the
format value that has been passed to it as a parameter (see commit
6ae2ff23aa43 ("drm/client: Convert drm_client_buffer_addfb() to drm_mode_addfb2()").
That format parameter is determined in drm_fbdev_generic_helper_fb_probe()
via the drm_mode_legacy_fb_format() function - which only generates
formats suitable for little endian devices. So to fix this issue
switch to drm_driver_legacy_fb_format() here instead to take the
device endianness into consideration.

A sync-only job is meant to provide a synchronization point on a

The function ast_crtc_dpms() is left over from when the ast driver
did not implement atomic modesetting. But DPMS is not supported by
atomic modesetting and the helper is only called to enable or
disable the CRTC sync pulses. Inline the function into its callers.
To disable the CRTC, ast sets (AST_DPMS_VSYNC_OFF | AST_DPMS_HSYNC_OFF)
in VGACRB6. Replace the constants with the correct register constants
for VGACRB6.

The SCREEN_DISABLE bit controls scanout from display memory. The bit
affects all planes, so set it only in the CRTC's atomic enable and
disable functions.
A number of bugs affect this fix. First of all, ast_set_std_regs()
tries to set VGASR1 except for the SD bit. But the read bitmask is
invert, so it preserves anything except the SD bit. Fix this by
re-inverting the read mask.
The second issue is that primary-plane and CRTC helpers modify the
SD bit. The bit controls scanout for all planes, primary and HW
cursor, so set it only in the CRTC code.
Further add a constant to represent the SD bit in VGASR1. Keep the
plane's atomic_disable around to make the DRM framework happy.

Several color registers are programmed in the DPMS code of the CRTC's
atomic_enable helper and the primary plane's atomic_update. It requires
the color format and the display mode.
Both code paths handle different cases: the DPMS's code will not be
executed if the color format changes without a full mode switch. The
plane's code only runs if the color format changes, but ignores
display-mode changes.
The color format is a property of the primary plane, so consolidate all
color-format code in the plane's atomic_update. Remove it from the DPMS
helper.

Do all mode setting in ast_crtc_helper_mode_set_nofb(), which
always runs after disabling the CRTC and before programming the
planes. Removes implicit synchronization between the CRTC's
atomic disable, enable and the vertical retrace.
Display-mode updates require HW cursors to be disabled. The HW
cursor only picks up changes at vertical retrace periods. So the
CRTC's atomic_disable helper waited for the retrace to delay any
following mode-setting operations, which then happened in
atomic_enable. See [1] for a description of the problem.
With the CRTC helper callback mode_set_nofb, we can now synchronize
and reprogram in the same place. As it always runs before the plane
update, the plane code can be reordered with the CRTC's later
atomic_enable et al.

The encoding of an x86 instruction can include a ModR/M and a SIB
(Scale-Index-Base) byte to describe the addressing mode of the
instruction.
objtool processes all addressing mode with a SIB base of 5 as having
%rbp as the base register. However, a SIB base of 5 means that the
effective address has either no base (if ModR/M mod is zero) or %rbp
as the base (if ModR/M mod is 1 or 2). This can cause objtool to confuse
an absolute address access with a stack operation.
For example, objtool will see the following instruction:
4c 8b 24 25 e0 ff ff mov 0xffffffffffffffe0,%r12
as a stack operation (i.e. similar to: mov -0x20(%rbp), %r12).
[Note that this kind of weird absolute address access is added by the
compiler when using KASAN.]
If this perceived stack operation happens to reference the location
where %r12 was pushed on the stack then the objtool validation will
think that %r12 is being restored and this can cause a stack state
mismatch.
This kind behavior was seen on xfs code, after a minor change (convert
kmem_alloc() to kmalloc()):
>> fs/xfs/xfs.o: warning: objtool: xfs_da_grow_inode_int+0x6c1: stack state mismatch: reg1[12]=-2-48 reg2[12]=-1+0

Rather than invoking a separate addr2line process for each address, invoke
a single addr2line coprocess, and pass each address to its stdin. Previous
work [0] applied a similar change to perf, leading to a ~60x speed-up [1].
If using an object file that is _not_ vmlinux, faddr2line passes a section
name argument to addr2line. Because we do not know until runtime which
section names will be passed to addr2line, we cannot apply this change to
non-vmlinux object files. Hence, it only applies to vmlinux.

In earlier revisions of the driver, the attributes array in
cros_chctl_priv had four elements with four distinct assignments but
during review, the number of elements was changed to three through use
of an enum and the assignments became a for loop, except for this one,
which is now out of bounds. This assignment is no longer necessary
because the size of the attributes array no longer accounts for it, so
just remove it to clear up the warning.

cifs_expand_read() is causing a performance regression of around 30% by
causing extra pagecache to be allocated for an inode in the readahead path
before we begin actually dispatching RPC requests, thereby delaying the
actual I/O. The expansion is sized according to the rsize parameter, which
seems to be 4MiB on my test system; this is a big step up from the first
requests made by the fio test program.
Simple repro (look at read bandwidth number):
fio --name=writetest --filename=/xfstest.test/foo --time_based --runtime=60 --size=16M --numjobs=1 --rw=read
Fix this by removing cifs_expand_readahead(). Readahead expansion is
mostly useful for when we're using the local cache if the local cache has a
block size greater than PAGE_SIZE, so we can dispense with it when not
caching.

Abstract the memory type from the page_pool so we can later add support
for new memory types. Convert the page_pool to use the new netmem type
abstraction, rather than use struct page directly.
As of this patch the netmem type is a no-op abstraction: it's always a
struct page underneath. All the page pool internals are converted to
use struct netmem instead of struct page, and the page pool now exports
2 APIs:
1. The existing struct page API.
2. The new struct netmem API.
Keeping the existing API is transitional; we do not want to refactor all
the current drivers using the page pool at once.
The netmem abstraction is currently a no-op. The page_pool uses
page_to_netmem() to convert allocated pages to netmem, and uses
netmem_to_page() to convert the netmem back to pages to pass to mm APIs,
Follow up patches to this series add non-paged netmem support to the
page_pool. This change is factored out on its own to limit the code
churn to this 1 patch, for ease of code review.

The cause is due to the idxd driver interrupt completion handler uses
threaded interrupt and the threaded handler is not hard or soft interrupt
context. However __netif_rx() can only be called from interrupt context.
Change the call to netif_rx() in order to allow completion via normal
context for dmaengine drivers that utilize threaded irq handling.
While the following commit changed from netif_rx() to __netif_rx(),
baebdf48c360 ("net: dev: Makes sure netif_rx() can be invoked in any context."),
the change should've been a noop instead. However, the code precedes this
fix should've been using netif_rx_ni() or netif_rx_any_context().

Currently clk-gate tests for s390 fail as the tests create a pretend
clk-gate and use a "fake_reg" to emulate the expected behavior of the
clk_gate->reg. I added some debug statements to the driver and noticed
that the reg changes after initialization to -1, which is coming from an
error coming from zpci_load(). This is likely because the test is using
fake iomem and the s390 architecture likely isn't designed to handle
that. Turn off the clk-gate tests for s390 for now as there is no clear
work around for this problem as discussed in upstream conversation [1].

In the past, the exclude_guest setting has had no effect on Intel PT
tracing, but that may not be the case in the future.
Set the flag correctly based upon whether KVM is using Intel PT
"Host/Guest" mode, which is determined by the kvm_intel module
parameter pt_mode:
pt_mode=0 System-wide mode : host and guest output to host buffer
pt_mode=1 Host/Guest mode : host/guest output to host/guest
buffers respectively
