Hi Ingo,
I am resending this series with changes based on your review of v3:
I have not noticed that v3 2/5 patch "x86, MSI: Allocate as many
multiple IRQs as requested" is redundant, since the AHCI code
tries to allocate maximum possible number of MSIs. As there are
no other users of this functionality, I removed v3 2/5 patch for now;
v3 patch 3/5 "x86, MSI: Minor readability fixes" merged into
v4 patch 1/3 "x86, MSI: Support multiple MSIs in presense of IRQ
remapping";
1/3: - racy can_create_irqs() check removed;
- multi-line comments fixed;
- loops 'for (; i; i--)' changed to 'for (i--; i >= 0; i--)';
v1 was conditionally acked by Suresh
v2 concerned Yinghai's comments
2/3: v2 is acked by Bjorn, no changes since
3/3: - ahci_host_activate() failure path tested;
- ahci_port_priv::lock field commented;
- multi-line comments fixed;
- loops 'for (; i; i--)' changed to 'for (i--; i >= 0; i--)';
v3 was acked by Jeff

1/3 x86, MSI: Support multiple MSIs in presense of IRQ remapping
2/3 PCI, MSI: Enable multiple MSIs with pci_enable_msi_block_auto()
3/3 AHCI: Support multiple MSIs
