2007-05-19kbuild: make better section mismatch reports on i386, arm and mipsAtsushi Nemoto
On i386, ARM and MIPS, warn_sec_mismatch() sometimes fails to show usefull symbol name. This is because empty 'refsym' due to 0 r_addend value. This patch is to adjust r_addend value, consulting with apply_relocate() routine in kernel code. Without this patch: MODPOST vmlinux WARNING: init/built-in.o - Section mismatch: reference to .init.text: from .text between 'rest_init' (at offset 0xf4) and 'try_name' WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap' WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap' With this patch: MODPOST vmlinux WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap' WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap' Now modpost can detect "kernel_init" name (and whitelist it) and show "set_up_list3s" name.

2007-05-19powerpc: Fix the MODALIAS generation in modpost for of devicesSylvain Munaut
Since the devices may have multiple (or none) compatible properties, the uevent generated internally by the kernel may have multiple "C..." entries. So the MODALIAS stored in the module must have wilcard before and after the compatible entry. Also, if the 'compatible' field is not used for matching, there will be no 'C' and that must handled as well. The previous code handled all those case incorrectly and it "mostly" worked ... but not always.

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.

From the changelog: after this patch: ... delayed_work_timer_fn->__queue_work() in progress. The latter doesn't differ from the caller's POV, it does make a difference if the caller calls flush_workqueue() after cancel_delayed_work(), in that case flush_workqueue() can miss this work_struct.

This reverts commit c8fdd247255a3a027cd9f66dcf93e6847d1d2f85. It turns out the kernel was correct, and the gcc complaint was a gcc bug. The preferred stack boundary is expressed not in bytes, but in the the log2() of the preferred boundary, so "-mpreferred-stack-boundary=2" is in fact exactly what we want, but a gcc that is compiled for x86-64 will consider it an error (because the 64-bit calling sequence says that the stack should be 16-byte aligned) even if we are then using "-m32" to generate 32-bit code.

2007-05-17e1000: Fix msi enable leak on error, don't print error message, cleanupAuke Kok
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. The whole code also needed a cleanup, so I combined the two different calls to pci_request_irq into a single call making this look a lot better. All #ifdef CONFIG_PCI_MSI's have been removed.

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.

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.

2007-05-17[BLUETOOTH]: Fix locking in hci_sock_dev_event().Satyam Sharma
We presently use lock_sock() to acquire a lock on a socket in hci_sock_dev_event(), but this goes BUG because lock_sock() can sleep and we're already holding a read-write spinlock at that point. So, we must use the non-sleeping BH version, bh_lock_sock(). However, hci_sock_dev_event() is called from user context and hence using simply bh_lock_sock() will deadlock against a concurrent softirq that tries to acquire a lock on the same socket. Hence, disabling BH's before acquiring the socket lock and enable them afterwards, is the proper solution to fix socket locking in hci_sock_dev_event().
