Summary: Bug/Regression On The kernel starting with 4.5-rc1 to
4.10-rc5 causing Slowness .

Hello Im Filling this bug here Because i Did a Git Bisect between the kernel
4.4 which is fine and faster and the kernel 4.5-rc1 which introduced the
slowness all the way up to 4.10-rc5 and this is what i get :
By Slowness Im Talking About Slow Compile Time And 3d Games Slow as hell.
On The kernel 4.1.37 and 4.4.44 i can compile the kernel Sources in 13 Minutes.
And With The kernel 4.9.6 which is the last stable in almost 30 Minutes.
Both's kernels with the governor Performance set .
And Slow 3d Games For Example the games on ppsspp emulator are too Slow.
Tested With Kernels 4.5-rc1 to 4.10-rc5 all of them are slow.
With the kernels 4.1 lts and 4.4 lts the games are normal .

drm/i915: Type safe register read/write
Make I915_READ and I915_WRITE more type safe by wrapping the register
offset in a struct. This should eliminate most of the fumbles we've had
with misplaced parens.
This only takes care of normal mmio registers. We could extend the idea
to other register types and define each with its own struct. That way
you wouldn't be able to accidentally pass the wrong thing to a specific
register access function.
The gpio_reg setup is probably the ugliest thing left. But I figure I'd
just leave it for now, and wait for some divine inspiration to strike
before making it nice.
As for the generated code, it's actually a bit better sometimes. Eg.
looking at i915_irq_handler(), we can see the following change:
lea 0x70024(%rdx,%rax,1),%r9d
mov $0x1,%edx
- movslq %r9d,%r9
- mov %r9,%rsi
- mov %r9,-0x58(%rbp)
- callq *0xd8(%rbx)
+ mov %r9d,%esi
+ mov %r9d,-0x48(%rbp)
callq *0xd8(%rbx)
So previously gcc thought the register offset might be signed and
decided to sign extend it, just in case. The rest appears to be
mostly just minor shuffling of instructions.
v2: i915_mmio_reg_{offset,equal,valid}() helpers added
s/_REG/_MMIO/ in the register defines
mo more switch statements left to worry about
ring_emit stuff got sorted in a prep patch
cmd parser, lrc context and w/a batch buildup also in prep patch
vgpu stuff cleaned up and moved to a prep patch
all other unrelated changes split out
v3: Rebased due to BXT DSI/BLC, MOCS, etc.
v4: Rebased due to churn, s/i915_mmio_reg_t/i915_reg_t/
