* sched: rename SCHED_NO_NO_OMIT_FRAME_POINTER => SCHED_OMIT_FRAME_POINTERIngo Molnar2008-11-111-1/+1
| | | | | | | | | | | | | | Impact: cleanup, change .config option name We had this ugly config name for a long time for hysteric raisons. Rename it to a saner name. We still cannot get rid of it completely, until /proc/<pid>/stack usage replaces WCHAN usage for good. We'll be able to do that in the v2.6.29/v2.6.30 timeframe.

| * net: Fix recursive descent in __scm_destroy().David S. Miller2008-11-072-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

It should take a 'u64 ns' argument, but rather takes an 'unsigned long ns' argument - which might only be 32-bits. On FRV, this results in the kernel locking up because hrtimer_forward() passes the result of a 64-bit multiplication to this function, for which the compiler discards the top 32-bits - something that didn't happen when ktime_add_ns() was called directly.

These effectively match the word address 0x555 and 0x2aa, except the latter has its low bit set. Most chips don't care about the value of the 'A-1' pin in x8 mode, but some -- like the ST M29W320D -- do. So we need to be careful to set it where appropriate. cfi_send_gen_cmd is only ever passed addresses where the low byte is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are affected by this patch, by masking in the extra low bit when the device is known to be in compatibility mode.

The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

Lots of devices have known good bridges that don't need this limit applied. The MTRON SSD disks are such devices. Transfer rates are increased by 20-30% with the restriction removed. So add a "blacklist" entry for the MTRON devices, with a flag indicating that the bridge is known good. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Okajima reported a problem where knfsd crashes if you are using it to export shmemfs objects and run strict overcommit. In this situation the current->mm based modifier to the overcommit goes through a NULL pointer. We could simply check for NULL and skip the modifier but we've caught other real bugs in the past from mm being NULL here - cases where we did need a valid mm set up (eg the exec bug about a year ago). To preserve the checks and get the logic we want shuffle the checking around and add a new helper to the vm_ security wrappers Also fix a current->mm reference in nommu that should use the passed mm [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: fix build] Reported-by: Junjiro R.

The Linux kernel defaulted to 32k (on a 4k page size system) to accommodate the needs of gpg. However, newer gpg2 needs 64k in various circumstances and otherwise fails miserably, see bnc#329675. Change the default to 64k, and make it more agnostic to PAGE_SIZE.
