2010-05-04x86, ioapic: Teach mp_register_ioapic to compute a global gsi_endEric W. Biederman
Add the global variable gsi_end and teach mp_register_ioapic to keep it uptodate as we add more ioapics into the system. ioapics can only be added early in boot so the code that runs later can treat gsi_end as a constant. Remove the have hacks in sfi.c to second guess mp_register_ioapic by keeping t's own running total of how many gsi's have been seen, and instead use the gsi_end. Signed-off-by: Eric W.

2010-05-04x86, ioapic: Fix the types of gsi valuesEric W. Biederman
This patches fixes the types of gsi_base and gsi_end values in struct mp_ioapic_gsi, and the gsi parameter of mp_find_ioapic and mp_find_ioapic_pin A gsi is cannonically a u32, not an int.

2010-05-04x86, ioapic: Fix io_apic_redir_entries to return the number of entries.Eric W. Biederman
io_apic_redir_entries has a huge conceptual bug. It returns the maximum redirection entry not the number of redirection entries. Which simply does not match what the name of the function. This just caught me and it caught Feng Tang, and Len Brown when they wrote sfi_parse_ioapic. Modify io_apic_redir_entries to actually return the number of redirection entries, and fix the callers so that they properly handle receiving the number of the number of redirection table entries, instead of the number of redirection table entries less one. While the usage in sfi.c does not show up in this patch it is fixed by virtue of the fact that io_apic_redir_entries now has the semantics sfi_parse_ioapic most reasonably expects.

2010-05-04x86, acpi/irq: Generalize mp_config_acpi_legacy_irqsEric W. Biederman
Remove the assumption that there is not an override for isa irq 0. Instead lookup the gsi and from that lookup the ioapic and pin of each isa irq indivdually. In general this should not have any behavioural affect but in perverse cases this gets all of the details correct, instead of doing something weird. Signed-off-by: Eric W.

2010-05-04x86, acpi/irq: Fix acpi_sci_ioapic_setup so it has both bus_irq and gsiEric W. Biederman
Currently acpi_sci_ioapic_setup calls mp_override_legacy_irq with bus_irq == gsi, which is wrong if we are comming from an override Instead pass the bus_irq into acpi_sci_ioapic_setup. This fix was inspired by a similar fix from: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Eric W.

2010-05-04x86, acpi/irq: pci device dev->irq is an isa irq not a gsiEric W. Biederman
Strictly speaking on x86 (where acpi is used) dev->irq must be a dual i8259 irq input aka an isa irq. Therefore we should translate that isa irq into a gsi before passing it to a function that takes a gsi. Signed-off-by: Eric W.

2010-05-04x86, acpi/irq: Teach acpi_get_override_irq to take a gsi not an isa_irqEric W. Biederman
In perverse acpi implementations the isa irqs are not identity mapped to the first 16 gsi. Furthermore at least the extended interrupt resource capability may return gsi's and not isa irqs. So since what we get from acpi is a gsi teach acpi_get_overrride_irq to operate on a gsi instead of an isa_irq. Signed-off-by: Eric W.

2010-05-04x86, acpi/irq: Introduce apci_isa_irq_to_gsiEric W. Biederman
There are a number of cases where the current code makes the assumption that isa irqs identity map to the first 16 acpi global system intereupts. In most instances that assumption is correct as that is the required behaviour in dual i8259 mode and the default behavior in ioapic mode. However there are some systems out there that take advantage of acpis interrupt remapping for the isa irqs to have a completely different mapping of isa_irq to gsi. Introduce acpi_isa_irq_to_gsi to perform this mapping explicitly in the code that needs it. Initially this will be just the current assumed identity mapping to ensure it's introduction does not cause regressions. Signed-off-by: Eric W.

If a rename operation is resent to the MDS following an MDS restart, the client does not get a full reply (containing the resulting metadata) back. In that case, a ceph_rename() needs to compensate by doing anything useful that fill_inode() would have, like d_move(). It also needs to invalidate the dentry (to workaround the vfs_rename_dir() bug) and clear the dir complete flag, just like fill_trace(). Signed-off-by: Sage Weil <sage@newdream.net>

2010-04-30MIPS: Loongson 2F: Fix of problems introduced by -mfix-loongson2f-jumpWu Zhangjin
The -mfix-loongson2f-jump option provided by latest CVS binutils have fixed the out-of-order issue of Loongson-2F described in chapter 15 of the Loongson2F User Manual [1, 2], but introduced some problems. The option changes all of the jump target to "addr & 0xcfffffff" through the at($1) register, but for the reboot address of Loongson 2F 0xbfc00000 this is wrong. Avoids the problem via telling the assembler to not use the $at register.

2010-04-30MIPS: Loongson: Add CPU_LOONGSON2F_WORKAROUNDSWu Zhangjin
As documented in the Loongson 2F User Manual [2, 3], the old Loongson2F series (2F01 / 2F02) have the NOP & JUMP issues which requires workarounds in the kernel and binutils. This issue has been rectified in Loongson 2F series 2F03 so no workarounds needed. Now that the workarounds [1] adding the the -mfix-loongson2f-nop and -mfix-loongson2f-jump options have been comitted to the binutils the CVS repository), we can add the workarounds in the kernel. The workarounds have no significant side effect on the system but may decrease performance so we control them through a a new CPU_LOONGSON2F_WORKAROUNDS config option allowing the users to only enable it as necessary.

Before this we were using XKPHYS/cached as ebase and computed the uncached xphsys/unchached address for that area.

2010-04-30MIPS: Check for accesses beyond the end of the PGD.David Daney
For some combinations of PAGE_SIZE and vmbits, it is possible to have userspace access that are beyond what is covered by the PGD, but within vmbits. Such an access would cause the TLB refill handler to load garbage values for PMD and PTE potentially giving userspace access to parts of the physical address space to which it is not entitled. In the TLB refill hot path, we add a single dsrl instruction so we can check if any bits outside of the range covered by the PGD are set. In the vmalloc side we then separate the bad case from the normal vmalloc case and call tlb_do_page_fault_0 if warranted. This slows us down a bit, but has the benefit of yielding deterministic behavior.

2010-04-30MIPS: Swarm, Littlesur: Enable PATA platform driver.Sebastian Andrzej Siewior
According to include/asm/sibyte/swarm.h both systems provide a platform device for the ide controler. Until now the IDE subsystem was used which is deprecated by now. The same structure can be used with the PATA driver.

2010-04-30MIPS: DB1200: PCMCIA card detection must not be auto-enabled.Manuel Lauss
Same issues as SD card detection: One of both is always triggering and the handlers take care to shut it up and enable the other. To avoid messages about "unbalanced interrupt enable/disable" they must not be automatically enabled when initally requested. This was not an issue with the db1200_defconfig due to fortunate timings; on a build without network chip support the warnings appear.

2010-04-30MIPS: Don't vmap things at address zero.David Daney
In the 64-bit kernel we use swapper_pg_dir for three different things. 1) xuseg mappings for kernel threads. 2) vmap mappings for all kernel-space accesses in xkseg. 3) vmap mappings for kernel modules in ksseg (kseg2). Due to how the TLB refill handlers work, any mapping established in xkseg or ksseg will also establish a xuseg mapping that should never be used by the kernel. In order to be able to use exceptions to trap NULL pointer dereferences, we need to ensure that nothing is mapped at address zero. Since vmap mappings in xkseg are reflected in xuseg, this means we need to ensure that there are no vmap mappings established at the start of xkseg. So we move back VMALLOC_START to avoid establishing vmap mappings at the start of xkseg.
