2009-12-23be2net: Bug fix to avoid soft lockup in loopback test.Sarveshwar Bandi
This change ensures that loopback test command gives up after 4 seconds when the hardware is not responsive. This could happen if the ports are connected properly in loopback mode. Signed-off-by: Sarveshwar Bandi <sarveshwarb@serverengines.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-12-23igb: do not force retry count to 1 on 82580 phyAlexander Duyck
This change resolves an issue seen in some configurations where the link may drop to 100Mb/s even though the link itself supports 1000Mb/s. The issue was root caused to the fact that we were only trying the link once. Now instead we will try up to 5 attempts on a faulty cable before downshifting to 100Mb/s.

2009-12-23sony-laptop: enumerate rfkill devices using SN06Mattia Dongili
SN06 makes sure we get back a longer buffer which seems to be necessary going forward as the SNC devices describes more and more devices (or features more precisely). Moreover SN06 should be called with only the descriptor offset to make sure we hit the rfkill controlling function (F124 or F135) with a 0 argument to get a full list of features.

The PHY boots in a mode which is not necessarily optimal.

2009-12-24i2c-omap: OMAP3: Fix I2C lockup during timeout/error casesManjunatha GK
Current OMAP3 I2C driver code does not follow the correct sequence for soft reset. Due to this, lock up issues are reported during timeout/error cases. This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM for soft reset. As per TRM, I2C controller needs to be disabled as a first step during soft reset. Here is correct soft reset sequence: a. Ensure that the module is disabled (clear the I2Ci.I2C_CON[15] I2C_EN bit to 0). b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1. c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1. d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to indicate the software reset is complete.

2009-12-24i2c-omap: Don't write IE state in unidle if 0Cory Maccarrone
Commit ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer to support off-mode) introduced a change which make the dev->iestate contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle is called. Previously, the state was only written if it wasn't equal to zero. In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(), in which case dev->iestate has not yet been initialized and will be set to zero. Having this value written to the registers causes deadlock while booting. As such, this change restores the original functionality.

2009-12-23Revert "x86, ucode-amd: Ensure ucode update on suspend/resume after CPU ↵Linus Torvalds
off/online cycle" This reverts commit 9f15226e75583547aaf542c6be4bdac1060dd425. It's just wrong, and broke resume for Rafael even on a non-AMD CPU. As Rafael says: "... it causes microcode_init_cpu() to be called during resume even for CPUs for which there's no microcode to apply. That, in turn, results in executing request_firmware() (on Intel CPUs at least) which doesn't work at this stage of resume (we have device interrupts disabled, I/O devices are still suspended and so on). If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is known to us" , so before commit 9f15226e755 microcode_resume_cpu() was called for all CPUs already in the system during suspend, which was the right thing to do. The commit changed it so that the CPUs without microcode to apply are now treated as "unknown", which is not quite right. The problem this commit attempted to solve has to be handled differently."

2009-12-23SYSCTL: Print binary sysctl warnings (nearly) only onceAndi Kleen
When printing legacy sysctls print the warning message for each of them only once. This way there is a guarantee the syslog won't be flooded for any sane program. The original attempt at this made the tables non const and stored the flag inline. Linus suggested using a separate hash table for this, this is based on a code snippet from him. The hash implies this is not exact and can sometimes not print a new sysctl due to a hash collision, but in practice this should not be a problem I used a FNV32 hash over the binary string with a 32byte bitmap. This gives relatively little collisions when all the predefined binary sysctls are hashed: size 256 bucket length number 0: [25] 1: [67] 2: [88] 3: [47] 4: [22] 5: [6] 6: [1] The worst case is a single collision of 6 hash values.
