65f0539b1d firmware: xilinx: Fix an error handling path in 'zynqmp_firmware_probe()'
If 'mfd_add_devices()' fails, we must undo 'zynqmp_pm_api_debugfs_init()'
otherwise some debugfs directory and files will be left.

Just move the call to 'zynqmp_pm_api_debugfs_init()' a few lines below to
fix the issue.

e99332e7b4 gcc-10: mark more functions __init to avoid section mismatch warnings
It seems that for whatever reason, gcc-10 ends up not inlining a couple
of functions that used to be inlined before.  Even if they only have one
single callsite - it looks like gcc may have decided that the code was
unlikely, and not worth inlining.

The code generation difference is harmless, but caused a few new section
mismatch errors, since the (now no longer inlined) function wasn't in
the __init section, but called other init functions:

   Section mismatch in reference from the function kexec_free_initrd() to the function .init.text:free_initrd_mem()
   Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memremap()
   Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap()

So add the appropriate __init annotation to make modpost not complain.
In both cases there were trivially just a single callsite from another
__init function.

56a9a80686 firmware: xilinx: Export zynqmp_pm_fpga_{get_status,load}
When building arm64 allmodconfig:

ERROR: modpost: "zynqmp_pm_fpga_load" [drivers/fpga/zynqmp-fpga.ko] undefined!
ERROR: modpost: "zynqmp_pm_fpga_get_status" [drivers/fpga/zynqmp-fpga.ko] undefined!

These functions were added to drivers/fpga/zynqmp-fpga.c but not
exported so the module build breaks. Export them so that they can be
used in modules properly.

a2cc220a9a firmware: xilinx: Add sysfs and API to set boot health status
Add sysfs interface to set boot health status from user space.
Add API used by this interface to communicate with firmware.

If PMUFW is compiled with CHECK_HEALTHY_BOOT, it will check the
healthy bit on FPD WDT expiration. If healthy bit is set by a user
application running in Linux, PMUFW will do APU only restart. If
healthy bit is not set during FPD WDT expiration, PMUFW will do
system restart.

b3ae24c448 firmware: xilinx: Add sysfs to set shutdown scope
The Linux shutdown functionality implemented via PSCI system_off does
not include an option to set a scope, i.e. which parts of the system to
shut down.

This patch creates sysfs that allows to set the shutdown scope for the
next shutdown request. When the next shutdown is performed, the platform
specific portion of PSCI-system_off can use the chosen shutdown scope.

The Intel service layer driver has defined error codes for the
specific services, which started from FPGA configuration then RSU
(Remote Status Update).

Intel service layer driver should define the standard error codes
rather than keep adding more error codes for the new services.

The standard error codes will be used by all the clients of Intel service
layer driver.

Replace FPGA and RSU specific error codes with Intel service layer’s
Common error codes.

 The debugfs change is now possible as now the last users of
 debugfs_create_u32() have been fixed up in the different trees that got
 merged into 5.7-rc1, and I don't want it creeping back in.
 
 The firmware changes did cause a regression in linux-next, so the final

32ec783ae1 firmware: imx: fix compile-testing
It is nice to allow compile-testing the firmware drivers, but this
fails when the dependency is a loadable module:

aarch64-linux-ld: drivers/firmware/imx/scu-pd.o: in function `imx_sc_pd_power':
scu-pd.c:(.text+0xd8): undefined reference to `imx_scu_call_rpc'
aarch64-linux-ld: scu-pd.c:(.text+0x108): undefined reference to `imx_scu_call_rpc'
aarch64-linux-ld: drivers/firmware/imx/scu-pd.o: in function `imx_sc_pd_probe':

Change the dependencies to ensure that any driver we depend on is
either reachable or we are compile-testing and it is disabled,
effectively reverting most of the previous changes that turned
out to be incorrect.

464fb126d9 efi/libstub/file: Merge file name buffers to reduce stack usage
Arnd reports that commit

  9302c1bb8e ("efi/libstub: Rewrite file I/O routine")

reworks the file I/O routines in a way that triggers the following
warning:

  drivers/firmware/efi/libstub/file.c:240:1: warning: the frame size
            of 1200 bytes is larger than 1024 bytes [-Wframe-larger-than=]

We can work around this issue dropping an instance of efi_char16_t[256]
from the stack frame, and reusing the 'filename' field of the file info
struct that we use to obtain file information from EFI (which contains
the file name even though we already know it since we used it to open
the file in the first place)

21cb9b4143 efi/x86: Always relocate the kernel for EFI handover entry
Commit

  d5cdf4cfea ("efi/x86: Don't relocate the kernel unless necessary")

tries to avoid relocating the kernel in the EFI stub as far as possible.

However, when systemd-boot is used to boot a unified kernel image [1],
the image is constructed by embedding the bzImage as a .linux section in
a PE executable that contains a small stub loader from systemd that will
call the EFI stub handover entry, together with additional sections and
potentially an initrd. When this image is constructed, by for example
dracut, the initrd is placed after the bzImage without ensuring that at
least init_size bytes are available for the bzImage. If the kernel is
not relocated by the EFI stub, this could result in the compressed
kernel's startup code in head_{32,64}.S overwriting the initrd.

To prevent this, unconditionally relocate the kernel if the EFI stub was
entered via the handover entry point.

105cb9544b efi/x86: Move efi stub globals from .bss to .data
Commit

  3ee372ccce ("x86/boot/compressed/64: Remove .bss/.pgtable from bzImage")

removed the .bss section from the bzImage.

However, while a PE loader is required to zero-initialize the .bss
section before calling the PE entry point, the EFI handover protocol
does not currently document any requirement that .bss be initialized by
the bootloader prior to calling the handover entry.

When systemd-boot is used to boot a unified kernel image [1], the image
is constructed by embedding the bzImage as a .linux section in a PE
executable that contains a small stub loader from systemd together with
additional sections and potentially an initrd. As the .bss section
within the bzImage is no longer explicitly present as part of the file,
it is not initialized before calling the EFI handover entry.
Furthermore, as the size of the embedded .linux section is only the size
of the bzImage file itself, the .bss section's memory may not even have
been allocated.

In particular, this can result in efi_disable_pci_dma being true even
when it was not specified via the command line or configuration option,
which in turn causes crashes while booting on some systems.

To avoid issues, place all EFI stub global variables into the .data
section instead of .bss. As of this writing, only boolean flags for a
few command line arguments and the sys_table pointer were in .bss and
will now move into the .data section.

0ad5b053d4 Char/Misc driver patches for 5.7-rc1
Here is the big set of char/misc/other driver patches for 5.7-rc1.
 
 Lots of things in here, and it's later than expected due to some reverts
 to resolve some reported issues.  All is now clean with no reported
 problems in linux-next.
 
 Included in here is:
 	- interconnect updates
 	- mei driver updates
 	- uio updates
 	- nvmem driver updates
 	- soundwire updates
 	- binderfs updates
 	- coresight updates
 	- habanalabs updates
 	- mhi new bus type and core
 	- extcon driver updates
 	- some Kconfig cleanups
 	- other small misc driver cleanups and updates
 
 As mentioned, all have been in linux-next for a while, and with the last
 two reverts, all is calm and good.

dbdd24eaac edd: Use scnprintf() for avoiding potential buffer overflow
Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

Ard Biesheuvel
e16e65a029 arm64: remove CONFIG_DEBUG_ALIGN_RODATA feature
When CONFIG_DEBUG_ALIGN_RODATA is enabled, kernel segments mapped with
different permissions (r-x for .text, r-- for .rodata, rw- for .data,
etc) are rounded up to 2 MiB so they can be mapped more efficiently.
In particular, it permits the segments to be mapped using level 2
block entries when using 4k pages, which is expected to result in less
TLB pressure.

However, the mappings for the bulk of the kernel will use level 2
entries anyway, and the misaligned fringes are organized such that they
can take advantage of the contiguous bit, and use far fewer level 3
entries than would be needed otherwise.

This makes the value of this feature dubious at best, and since it is not
enabled in defconfig or in the distro configs, it does not appear to be
in wide use either. So let's just remove it.
