2011-06-08microblaze/pci: Remove powermac originated cruftBenjamin Herrenschmidt3-275/+3
The whole business with re-assigning all bus numbers, creating an OF bus "map" etc... is ancient powermac stuff that you really don't care about on microblaze. Similarly pci_device_from_OF_node() is unused and by getting rid of it we can get rid of a whole lot of code otherwise unused on this architecture Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Michal Simek <monstr@monstr.eu>
2011-06-08pci/of: Match PCI devices to OF nodes dynamicallyBenjamin Herrenschmidt3-55/+14
powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

2011-05-28Merge branch 'setns'Linus Torvalds2-1/+3
* setns: ns: Wire up the setns system call Done as a merge to make it easier to fix up conflicts in arm due to addition of sendmmsg system call
2011-05-28ns: Wire up the setns system callEric W. Biederman2-1/+3
32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W. Biederman <ebiederm@xmission.com> v4: Moved wiring up of the system call to another patch v5: ported to v2.6.39-rc6 v6: rebased onto parisc-next and net-next to avoid syscall conflicts. v7: ported to Linus's latest post 2.6.39 tree. >  arch/blackfin/include/asm/unistd.h     |    3 ++- >  arch/blackfin/mach-common/entry.S      |    1 + Acked-by: Mike Frysinger <vapier@gentoo.org> Oh - ia64 wiring looks good.

This patch drops the reference to a global 'cmd_line' variable from early_init_dt_scan_chosen, and instead passes the pointer to the command line string via the *data argument. Each architecture does something slightly different with the initial command line, so it makes sense for the architecture to be able to specify the variable name.

2011-03-11futex: Sanitize cmpxchg_futex_value_locked APIMichel Lespinasse1-11/+13
The cmpxchg_futex_value_locked API was funny in that it returned either the original, user-exposed futex value OR an error code such as -EFAULT. This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

2011-03-09microblaze: Fix /dev/zero corruption from __clear_user()Steven J. Magnani1-4/+4
A userland read of more than PAGE_SIZE bytes from /dev/zero results in (a) not all of the bytes returned being zero, and (b) memory corruption due to zeroing of bytes beyond the user buffer. This is caused by improper constraints on the assembly __clear_user function. The constrints don't indicate to the compiler that the pointer argument is modified. Since the function is inline, this results in double-incrementing of the pointer when __clear_user() is invoked through a multi-page read() of /dev/zero. Signed-off-by: Steven J.
