Enable reliable use of Message-Signaled Interrupts (MSI) in sata_mv by masking further chip interrupts within the main interrupt handler. Based upon a suggestion by Grant Grundler. MSI is working reliably in all of my test systems here now.

I noticed that during initialization sata_mv.c assumes that the main interrupt mask has its default value of 0. The function mv_platform_probe(..) initializes a shadow irq mask with 0 assuming that's the value of the controller's register. Now mv_set_main_irq_mask(..) only writes the controller's register if the new value differs from the "shadowed" value. This is fatal when trying to disable all interrupts in mv_init_host(..), i.e. the following function call does not write anything to the main irq mask register: mv_set_main_irq_mask(host, ~0, 0); The effect I see on my machine (QNAP TS-109 II) with booting via kexec (with Linux as a 2nd-stage boot loader) is that if the sata_mv module was still loaded when performing kexec, then the new kernel's sata_mv module starts up with interrupts enabled. This results in an unhandled IRQ and breaks the boot process. The unhandled interrupt itself might also be fixed by Lennert's patch proposed at http://markmail.org/message/kwvzxstnlsa3s26w which I did not try yet. However I still propose to additionally initialize the shadow variable with the current contents of the main irq mask register to get both in sync and allow proper disabling the main irq mask. This fixes the unhandled irq on my machine. Signed-off-by: Thomas Reitmayr <treitmayr@devbase.at> Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Remove silly read-modify-write sequences when clearing interrupts in hc_irq_cause. This gets rid of unneeded MMIO reads, resulting in a slight performance boost when switching between EDMA and non-EDMA modes (eg. for cache flushes).

Fix a longstanding bug for the 8-port Marvell Sata controllers (508x/6081), where accesses to the upper 4 ports would cause lost-interrupts / timeouts for the lower 4-ports. With this patch, the 6081 boards should finally be reliable enough for mainstream use with Linux. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

MCP5x family of controllers seem to share much more with nf2's as far as reset protocol is concerned. It requires heardreset to get the PHY going and classfication code report after hardreset is unreliable. Create a new board type MCP5x and use noclassify hardreset. SWNCQ is modified to inherit from this new type. This fixes hotplug regression reported in kernel bz#12351. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Asus Pundit-R with atiixp controller has the second port missing and, very unusually, its status is stuck at 0x7f and all others at 0. This meanst that it fails TF access test but gets detected as a disk due to classification code check and then evades polling IDENTIFY presence detection thanks to the missing BSY in the status value causing excessive delays during boot. This patch makes libata-sff HSM set NODEV_HINT if the status is 0x7f to make polling IDENTIFY presence detection work for these machines.

Uwe Kleine-König authored
A pointer to wm8400_regulator_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

The current work request posting code writes the LSO segment before writing any data segments. This leaves a window where the LSO segment overwrites the stamping in one cacheline that the HCA prefetches before the rest of the cacheline is filled with the correct data segments. When the HCA processes this work request, a local protection error may result. Fix this by saving the LSO header size field off and writing it only after all data segments are written. This fix is a cleaned-up version of a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1383>.
