Some G5 recent powermacs start with the fan control unit (FCU) disabled, by the firmware, causing the thermal control driver to break. We have to enable it before starting the feedback loops that set the fan speeds. This patch adds the code to start the FCU. Signed-off-by:

On old powermacs, it's possible that we get a stale edge interrupt when doing request_irq(), that typically happens with the DBDMA controller interrupts when the device was used by the firmware for booting. I just tracked down a nasty memory corruption problem where that was causing the bmac driver to try to process packets before the driver internal data structures were properly initialized. While I agree that the driver should (and will) be made more robust to such things, Paulus and I decided that it makes little sense to keep track of an "old" edge interrupt that happens before a driver does request_irq. (On those powermacs, those are only the DBDMA interrupts anyway, and none of the DBDMA users will care). This patch implements a "startup" handler for the old Apple PIC that will "ack" pending edge interrupts before unmasking, thus preventing those stale interrupts to be delivered. It also "fixes" the ppc32 irq core to call the startup() callback when available instead of just calling enable(). Signed-off-by:

blk_rq_map_user() is a bit of a hack currently, since it drops back to kmalloc() if bio_map_user() fails. This is unfortunate since it means we do no real segment or size checking (and the request segment counts contain crap, already found one bug in a scsi lld). It's also pretty nasty for > PAGE_SIZE requests, as we attempt to do higher order page allocations. Even worse still, ide-cd will drop back to PIO for non-sg/bio requests. All in all, very suboptimal. This patch adds bio_copy_user() which simply sets up a bio with kernel pages and copies data as needed for reads and writes. It also changes bio_map_user() to return an error pointer like bio_copy_user(), so we can return something sane to the user instead of always -ENOMEM. Signed-off-by:

This patch moves xfrm[46]_tunnel_check_size() into xfrm[46]_output.c where it can be made static since it's only used there. While moving the icmp.h inclusions over I also discovered that the tunnel files are missing an inclusion of net/protocol.h. So I've added them as well. Signed-off-by:

This is a couple of clean-ups stemming from the xfrm_output change. I should've removed the inet_ecn.h inclusions in that change as the ECN code has been moved to xfrm[46]_output.c. This patch does exactly that. Signed-off-by:

Previously, fatfs was using NLS_DEFAULT if users didn't specify the codepage or iocharset option. This became cause of trouble (filename access). This patch removes the complicated default config in kernel. Instead of it, by default, fatfs uses builtin nls ("default"), also reports it and mounts as read-only. This default will limit the access more or less. Note: If peoples want to write on this default, it still can switch by remount. Therefore, basically users will need to specify mount options always. ("codepage" for msdos, and "codepage" and "iocharset" for vfat) However, it can be done simply by script or shell alias or something else in userland. Thanks to Andries Brouwer for your many advice.

There is a lonstanding off-by-one error that results from an incorrect comparison when checking whether a process has consumed CPU time in excess of its RLIMIT_CPU limits. This means, for example, that if we use setrlimit() to set the soft CPU limit (rlim_cur) to 5 seconds and the hard limit (rlim_max) to 10 seconds, then the process only receives a SIGXCPU signal after consuming 6 seconds of CPU time, and, if it continues consuming CPU after handling that signal, only receives SIGKILL after consuming 11 seconds of CPU time. The fix is trivial. Signed-off-by: -

Here are some oops I found in error paths in the mounting pathes while debugging something else... I sent it out a while ago, but it didn't seem to get any traction.... The nfs_fill_super() fix is obvious and in nfs4_fill_super(), the server->client ptr needs to be set before the cl_idmap check, since rpc_shutdown_client() needs it when the check fails.

Actually, the problem has its origin in my removal of all in-kernel syscalls (except execve, which is non-trivial) earlier this year. This change was blindly reverted by the maintainer, while at the same time the local errno variable was removed. See also http://linux.bkbits.net:8080/linux-2.5/hist/drivers/media/dvb/frontends/tda= 1004x.c This patch is the one that was already merged earlier. I'm now also removing the definitions for the kernel syscalls on i386 to make it harder to reintroduce them again. This was already done for ppc64, the others should probably follow. Signed-off-by:

The "vector" terminology is architecture-dependent. The PCI MSI interface actually deals with Linux IRQ numbers (i.e., things you can pass to request_irq()), and we shouldn't confuse things by calling them "vectors" just because we're using MSI rather than an IOSAPIC. Signed-off-by:

Second half of MSI rewrite: fix the API and update documentation. Split enabling MSI and MSI-X to separate pci_enable_msi()/pci_disable_msi() and pci_enable_msix()/pci_disable_msix() functions. free_irq() no longer has the side effect of freeing interrupt vectors (so a device driver can do multiple request_irq()/free_irq() cycles on the same MSI/MSI_X vector).

On a system with a lot of nodes, 4 lines of output per node is a lot to have to sit through as the system comes up, especially if you're on the other end of a slow serial link. The information is valuable though, so keep it around for the system logger. This patch makes the printks for the memory stats use KERN_DEBUG instead of the default loglevel. Signed-off-by:
