(ARM: 6395/1: VExpress: Set bit 22 in the PL310 (cache controller) AuxCtlr register).

Actually, S5PV310 has same cache controller(PL310).

Following is from Catalin Marinas' commit.

Clearing bit 22 in the PL310 Auxiliary Control register (shared
attribute override enable) has the side effect of transforming Normal
Shared Non-cacheable reads into Cacheable no-allocate reads.

Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.

13 years agox86/microcode: Fix double vfree() and remove redundant pointer checks before vfree()
Jesper Juhl [Sat, 25 Dec 2010 18:57:41 +0000 (19:57 +0100)]
x86/microcode: Fix double vfree() and remove redundant pointer checks before vfree()

In arch/x86/kernel/microcode_intel.c::generic_load_microcode()
we have  this:

while (leftover) {
...
if (get_ucode_data(mc, ucode_ptr, mc_size) ||
    microcode_sanity_check(mc) < 0) {
vfree(mc);
break;
}
...
}

if (mc)
vfree(mc);

This will cause a double free of 'mc'. This patch fixes that by
just  removing the vfree() call in the loop since 'mc' will be
freed nicely just  after we break out of the loop.

There's also a second change in the patch. I noticed a lot of
checks for  pointers being NULL before passing them to vfree().
That's completely  redundant since vfree() deals gracefully with
being passed a NULL pointer.  Removing the redundant checks
yields a nice size decrease for the object  file.

libata: issue DIPM enable commands with LPM state updated

Low level drivers may behave differently depending on the current
link->lpm_policy.  During ata_eh_set_lpm(), DIPM enable commands are
issued after the successful completion of ap->ops->set_lpm(), which
means that the controller is already in the target state.  This causes
DIPM enable commands to be processed with mismatching controller power
state and link->lpm_policy value.

In ahci, link->lpm_policy is used to ignore certain PHY events if LPM
is enabled; however, as DIPM commands are issued with stale
link->lpm_policy, they sometimes end up triggering these conditions
and get aborted leading to LPM configuration failure.

Fix it by updating link->lpm_policy before issuing DIPM enable
commands.
