commit 5bbc6604a62814511c32f2e39bc9ffb2c1b92cbe upstream.
The offset into the array was specified in bytes but should
be in terms of 32-bit words. Also prevent large reads that
would also cause a buffer overread.
v2: Read from correct offset from internal storage buffer.

[ Upstream commit a28fda312a9fabdf0e5f5652449d6197c9fb0a90 ]
Problem:
During GPU reset we call the GPU scheduler to suspend it's
thread, those two functions in amdgpu also suspend and resume
the sceduler for their needs but this can collide with GPU
reset in progress and accidently restart a suspended thread
before time.
Fix:
Serialize with GPU reset.

Coccinelle reports a path that the array "data" is never initialized.
The path skips the checks in the conditional branches when either
of callback functions, read_wave_vgprs and read_wave_sgprs, is not
registered. Later, the uninitialized "data" array is read
in the while-loop below and passed to put_user().
Fix the path by allocating the array with kcalloc().
The patch is simplier than adding a fall-back branch that explicitly
calls memset(data, 0, ...). Also it does not need the multiplication
1024*sizeof(*data) as the size parameter for memset() though there is
no risk of integer overflow.

be a partial execution ib and mark it as preempted; so that the gfx

This prevents us from accessing extended registers in tools like
umr. The register access functions already check if the offset
is beyond the BAR size and use the indirect accessors with locking
so this is safe.

The error handling is wrong and "ent" could be NULL we when dereference
it to get "ent->d_inode".
The thing is that normally debugfs_create_file() is not supposed to
require (or have) any error handling. That function does return error
pointers if debugfs is turned off but we know it's enable here. When
it's enabled, then it returns NULL on error.
So what I did was I stripped out all the error handling except around
the i_size_write(). I could have just used a NULL check instead of an
IS_ERR_OR_NULL() but I figured this was more clear because that way you
don't have to look at the surrounding code to see whether debugfs is
enabled or not.
