bdc7ee7a35 drm/amdgpu: Fix snprintf buffer size in smu_v14_0_init_microcode
This commit addresses buffer overflow in the smu_v14_0_init_microcode
function. The issue was about the snprintf function writing more bytes
into the fw_name buffer than it can hold.

The line of code is:

snprintf(fw_name, sizeof(fw_name), "amdgpu/%s.bin", ucode_prefix);

Here, snprintf is used to write a formatted string into fw_name. The
format is "amdgpu/%s.bin", where %s is a placeholder for the string
ucode_prefix. The sizeof(fw_name) argument tells snprintf the maximum
number of bytes it can write into fw_name, including the
null-terminating character. In the original code, fw_name is an array of
30 characters.

The string "amdgpu/%s.bin" could be up to 41 bytes long, which exceeds
the 30 bytes allocated for fw_name. This is because %s could be replaced
by ucode_prefix, which can be up to 29 characters long. Adding the 12
characters from "amdgpu/" and ".bin", the total length could be 41
characters.

To address this, the size of ucode_prefix has been reduced to 15
characters. This ensures that the maximum length of the string written into
fw_name does not exceed its capacity.

smu_13/14 etc. don't follow legacy scheme ie., amdgpu_ucode_legacy_naming

Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu14/smu_v14_0.c: In function ‘smu_v14_0_init_microcode’:

fa7bb2cac0 drm/amd/pm: Restore config space after reset
During mode-2 reset, pci config space registers are affected at device
side. However, certain platforms have switches which assign virtual BAR
addresses and returns the same even after device is reset. This
affects pci_restore_state() as it doesn't issue another config write, if
the value read is same as the saved value.

Add a workaround to write saved config space values from driver side.
Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence
restrict the workaround only to those.

   "Unpatched return thunk in use. This should not happen!" when running
   KVM selftests.
 
 * Fix a mostly benign bug in the gfn_to_pfn_cache infrastructure where KVM
   would allow userspace to refresh the cache with a bogus GPA.  The bug has
   existed for quite some time, but was exposed by a new sanity check added in
   6.9 (to ensure a cache is either GPA-based or HVA-based).
 
 * Drop an unused param from gfn_to_pfn_cache_invalidate_start() that got left
   behind during a 6.9 cleanup.
 
 * Fix a math goof in x86's hugepage logic for KVM_SET_MEMORY_ATTRIBUTES that
   results in an array overflow (detected by KASAN).
 
 * Fix a bug where KVM incorrectly clears root_role.direct when userspace sets
   guest CPUID.
 
 * Fix a dirty logging bug in the where KVM fails to write-protect SPTEs used
   by a nested guest, if KVM is using Page-Modification Logging and the nested
   hypervisor is NOT using EPT.
 
 x86 PMU:
 
 * Drop support for virtualizing adaptive PEBS, as KVM's implementation is
   architecturally broken without an obvious/easy path forward, and because
   exposing adaptive PEBS can leak host LBRs to the guest, i.e. can leak
   host kernel addresses to the guest.
 
 * Set the enable bits for general purpose counters in PERF_GLOBAL_CTRL at
   RESET time, as done by both Intel and AMD processors.
 
 * Disable LBR virtualization on CPUs that don't support LBR callstacks, as
   KVM unconditionally uses PERF_SAMPLE_BRANCH_CALL_STACK when creating the
   perf event, and would fail on such CPUs.
 
 Tests:
 
 * Fix a flaw in the max_guest_memory selftest that results in it exhausting
   the supply of ucall structures when run with more than 256 vCPUs.
 
 * Mark KVM_MEM_READONLY as supported for RISC-V in set_memory_region_test.

560d4e7738 A couple clk driver fixes, a build fix, and a deadlock fix.
- Mediatek mt7988 has broken PCIe because the wrong parent is used
 
  - Mediatek clk drivers may deadlock when registering their clks because
    the clk provider device is repeatedly runtime PM resumed and
    suspended during probe and clk registration. Resuming the clk
    provider device deadlocks with an ABBA deadlock due to genpd_lock and
    the clk prepare_lock. The fix is to keep the device runtime resumed
    while registering clks.
 
  - Another runtime PM related deadlock, this time with disabling unused
    clks during late init. We get an ABBA deadlock where a device is
    runtime PM resuming (or suspending) while the disabling of unused
    clks is happening in parallel. That runtime PM action calls into the
    clk framework and tries to grab the clk prepare_lock while the
    disabling of unused clks holds the prepare_lock and is waiting for
    that runtime PM action to complete. The fix is to runtime resume all
    the clk provider devices before grabbing the clk prepare_lock during
    disable unused.
 
  - A build fix to provide an empty devm_clk_rate_exclusive_get()
    function when CONFIG_COMMON_CLK=n
