* sparc64: Kill __show_regs().David S. Miller2008-07-31
| | | | | | | | | | | | | | | The story is that what we used to do when we actually used smp_report_regs() is that if you specifically only wanted to have the current cpu's registers dumped you would call "__show_regs()" otherwise you would call show_regs() which also invoked smp_report_regs(). Now that we killed off smp_report_regs() there is no longer any reason to have these two routines, just show_regs() is sufficient. Also kill off a stray declaration of show_regs() in sparc64_ksym.c Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Add __KERNEL__ ifdef protection to pt_regs helpers.David S. Miller2008-07-31
| | | | | | | | | Some of them use 'bool' and whatnot and therefore are not kosher for userspace, so don't export them there. Reported by Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Kill smp_report_regs().David S. Miller2008-07-31
| | | | | | | | All the call sites are #if 0'd out and we have a much more useful global cpu dumping facility these days. smp_report_regs() is way too verbose to be usable. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: Make global reg dumping even more useful.David S. Miller2008-07-31
| | | | | | | | | | Record one more level of stack frame program counter. Particularly when lockdep and all sorts of spinlock debugging is enabled, figuring out the caller of spin_lock() is difficult when the cpu is stuck on the lock. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: FUTEX_OP_ANDN fixMikael Pettersson2008-07-30
| | | | | | | | | | | | | | | | Correct sparc64's implementation of FUTEX_OP_ANDN to do a bitwise negate of the oparg parameter before applying the AND operation. All other archs that support FUTEX_OP_ANDN either negate oparg explicitly (frv, ia64, mips, sh, x86), or do so indirectly by using an and-not instruction (powerpc). Since sparc64 has and-not, I chose to use that solution. I've not found any use of FUTEX_OP_ANDN in glibc so the impact of this bug is probably minor. But other user-space components may try to use it so it should still get fixed. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net>

With the previous incarnation, some data wouldn't be freed if the packet transmit callback was never called. A theoretical drawback now is that, in PCs with more than one card, card A may complete() for a waiter on card B. But this is highly unlikely and its impact not serious. Bus manager B may reset bus B before the PHY config went out, but the next phy config on B should be fine. However, with a timeout of 100ms, this situation is close to impossible.

Descriptor addresses above 2G have been determined as the trigger: https://bugzilla.redhat.com/show_bug.cgi?id=435550 Two fixes are possible: - pci_set_consistent_dma_mask(pdev, DMA_31BIT_MASK); at least when IR descriptors are allocated, or - simply don't use dualbuffer. This fix implements the latter workaround. But we keep using dualbuffer on x86-32 which won't give us highmen (and thus physical addresses outside the 31bit range) in coherent DMA memory allocations. Right now we could for example also whitelist PPC32, but DMA mapping implementation details are expected to change there.

While queue the response and data in complete_transaction in fw-cdev.c, it will queue like this: |response(excluding padding bytes)|4 padding bytes|4 padding bytes|data. It queue 4 extra bytes. That is to say it use "&response + sizeof(response)" while other place of kernel and userspace library use "&response + offsetof (typeof(response), data)". So it will lost the last 4 bytes of data. This patch can fix it while not changing the struct definition. Signed-off-by: JiSheng Zhang <jszhang3@mail.ustc.edu.cn> This fixes responses to outbound block read requests on 64bit architectures.
