2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%). Cross-compile tested on all arm defconfigs, all mips defconfigs, all powerpc defconfigs, alpha alpha-up arm i386 i386-up i386-defconfig i386-allnoconfig ia64 ia64-up m68k mips parisc parisc-up powerpc powerpc-up s390 s390-up sparc sparc-up sparc64 sparc64-up um-x86_64 x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig as well as my two usual configs.

2007-05-18cciss: Fix pci_driver.shutdown while device is still activeGerald Britton
Fix an Oops in the cciss driver caused by system shutdown while a filesystem on a cciss device is still active. The cciss_remove_one function only properly removes the device if the device has been cleanly released by its users, which is not the case when the pci_driver.shutdown method is called. This patch adds a new cciss_shutdown function to better match the pattern used by various SCSI drivers: deactivate device interrupts and flush caches. It also alters the cciss_remove_one function to match and readds the __devexit annotation that was removed when cciss_remove_one was serving as the pci_driver.shutdown method.

pci_enable_msi failure is a normal event so we should not print any error. Going over the code I spotted a missing pci_disable_msi() leak when irq allocation fails.

2007-05-17gianfar: Add I/O barriers when touching buffer descriptor ownership.Scott Wood
The hardware must not see that is given ownership of a buffer until it is completely written, and when the driver receives ownership of a buffer, it must ensure that any other reads to the buffer reflect its final state. Thus, I/O barriers are added where required. Without this patch, I have observed GCC reordering the setting of bdp->length and bdp->status in gfar_new_skb. Hardware reordering was also theoretically possible. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-05-17ibm_emac: improved PHY supportEugene Surovegin
Original patch is from Jeff Haran <jharan@brocade.com> with my minor style fixes. His comments follow: The first problem was in the function that configures the PHY for autonegotiation, genmii_setup_aneg(). The original code does a read/modify/write of the autonegotiation advertizement register (reg 4), followed by a read/modify/write of the control register (reg 0). While the original code follows the proper procedure as per reading the IEEE specs, what I found is that on at least one PHY model (National DP83843) the read of the control register comes back with the soft reset bit set (bit 15). Because of the read/modify/write operation, this causes the write to write a 1 back to the reset bit, which initiates a software reset of the PHY. This software reset causes the PHY to return to its power up state which advertizes all modes of operation, thus negating the write to the autoneg advertizement register. The modification is to spin reading the control register until the soft reset bit is clear before doing the modify/write. The second problem was in the function that configures the PHY for forced operation, genmii_setup_forced(). The original code initiates a software reset operation via a write of a 1 to bit 15 of the control register (reg 0), but then proceeds to do a second write to that same register without waiting until that reset bit is cleared by the PHY itself (which according to the IEEE specs indicates that the PHY reset is complete). This is a violation of how one is supposed to use this software reset feature of these PHYs and I believe was the cause of mysterious, difficult to reproduce link failures that we've observed on some of our systems that use this driver. The fix is to modify the function so that it spins waiting for the reset bit to clear after doing the soft reset and before doing the subsequent write.

2007-05-17NS16550A: Restore HS settings in EXCR2 on resumeDavid Woodhouse
After a suspend/resume cycle, the UART may have been reset into low-speed mode -- either because it's actually been reset, or because the firmware pokes at the old-style divisor registers. If we detected it as a NS16550A SuperIO chip in the first place and set baud_base to 921600, then we should do so again in the resume path. This patch adds that code to serial8250_resume_port(), and also makes serial8250_resume() actually call serial8250_resume_port() for each port instead of just calling uart_resume_port() directly. And thus fixes serial port operation after suspend/resume. It also fixes a bogus comment where we write the EXCR2 register with a comment saying /* EXCR1 */ Signed-off-by: David Woodhouse <dwmw2@infradead.org> Acked-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-16libata: during revalidation, check n_sectors after device is configuredTejun Heo
Device might be resized during ata_dev_configure() due to HPA or (later) ACPI _GTF. Currently it's worked around by caching n_sectors before turning off HPA. The cached original size is overwritten if the device is reconfigured without being hardreset - which always happens after configuring trasnfer mode. If the device gets hardreset for some reason after that, revalidation fails with -ENODEV. This patch makes size checking more robust by moving n_sectors check from ata_dev_reread_id() to ata_dev_revalidate() after the device is fully configured. No matter what happens during configuration, a device must have the same n_sectors after fully configured to be treated as the same device.

2007-05-15[SPARC64]: Add hypervisor API negotiation and fix console bugs.David S. Miller
Hypervisor interfaces need to be negotiated in order to use some API calls reliably. So add a small set of interfaces to request API versions and query current settings. This allows us to fix some bugs in the hypervisor console: 1) If we can negotiate API group CORE of at least major 1 minor 1 we can use con_read and con_write which can improve console performance quite a bit. 2) When we do a console write request, we should hold the spinlock around the whole request, not a byte at a time. What would happen is that it's easy for output from different cpus to get mixed with each other. 3) Use consistent udelay() based polling, udelay(1) each loop with a limit of 1000 polls to handle stuck hypervisor console.
