amdgpu_virt_ras_get_cper_records() was using a large stack array
of ras_log_info pointers. This contributed to the frame size
warning on this function.
Replace the fixed-size stack array:
struct ras_log_info *trace[MAX_RECORD_PER_BATCH];
with a heap-allocated array using kcalloc().
We free the trace buffer together with out_buf on all exit paths.
If allocation of trace or out_buf fails, we return a generic RAS
error code.
This reduces stack usage and keeps the runtime behaviour
unchanged.
Fixes:
stack frame size: 1112 bytes (limit: 1024)

ras_umc_handle_bad_pages() function used a large local array:
struct eeprom_umc_record records[MAX_ECC_NUM_PER_RETIREMENT];
Move this array off the stack by allocating it with kcalloc()
and freeing it before return.
This reduces the stack frame size of ras_umc_handle_bad_pages()
and avoids the frame size warning.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../ras/rascore/ras_umc.c:498:5: warning: stack frame size (1208) exceeds limit (1024) in 'ras_umc_handle_bad_pages' [-Wframe-larger-than]
v2: Removed the duplicate ras_umc_get_new_records() invocation. (Lijo)

Support high-frequency querying sriov ras block error count:
1. Create shared memory and fills it with RAS_CMD__GET_LAL_LOC_STATUS
ras command.
2. The RAS_CMD_GET_ALL_BLOCK_ECC_STATUS command and shared
memory are registered to sriov host ras auto-update list
via RAS_CMD_SET_CMD_AUTO_UPDATE command.
3. Once sriov host detects ras error, it will automatically execute
RAS_CMD__GET_ALL_BLOCK_ECC_STATUS command and write the result to
shared memory.

In order to reduce the number of interactions with sriov
host and the amount of data exchanged, a set of ras commands
is first used to obtain the raw data used to generate cper
from the host, then, guest driver generates cper based
