2010-11-23ARM: 6490/1: MM: bugfix: initialize spinlock for init_mm.contextMyungJoo Ham1-0/+4
init_mm used at kernel/sched.c:idle_task_exit() has spin_lock (init_mm.context.id_lock) that is not initialized when spin_lock/unlock is called at an ARM machine. Note that mm_struct.context.id_lock is usually initialized except for the instance of init_mm at linux/arch/arm/mm/context.c Not initializing this spinlock incurs "BUG: pinlock bad magic" warning when spinlock debug is enabled. We have observed such instances when testing PM in S5PC210 machines.

2010-11-22xen/events: Use PIRQ instead of GSI value when unmapping MSI/MSI-X irqs.Konrad Rzeszutek Wilk1-1/+1
When we allocate a vector for MSI/MSI-X we save away the PIRQ, and the vector value. When we unmap (de-allocate) the MSI/MSI-X vector(s) we need to provide the PIRQ and the vector value. What we did instead was to provide the GSI (which was zero) and the vector value, and we got these unhappy error messages: (XEN) irq.c:1575: dom0: pirq 0 not mapped [ 7.733415] unmap irq failed -22 This patches fixes this and we use the PIRQ value instead of the GSI value.

2010-11-22of/phylib: Use device tree properties to initialize Marvell PHYs.David Daney1-0/+97
Some aspects of PHY initialization are board dependent, things like indicator LED connections and some clocking modes cannot be determined by probing. The dev_flags element of struct phy_device can be used to control these things if an appropriate value can be passed from the Ethernet driver. We run into problems however if the PHY connections are specified by the device tree. There is no way for the Ethernet driver to know what flags it should pass. If we are using the device tree, the struct phy_device will be populated with the device tree node corresponding to the PHY, and we can extract extra configuration information from there. The next question is what should the format of that information be? It is highly device specific, and the device tree representation should not be tied to any arbitrary kernel defined constants. A straight forward representation is just to specify the exact bits that should be set using the "marvell,reg-init" property: phy5: ethernet-phy@5 { reg = <5>; compatible = "marvell,88e1149r"; marvell,reg-init = /* led[0]:1000, led[1]:100, led[2]:10, led[3]:tx */ <3 0x10 0 0x5777>, /* Reg 3,16 <- 0x5777 */ /* mix %:0, led[0123]:drive low off hiZ */ <3 0x11 0 0x00aa>, /* Reg 3,17 <- 0x00aa */ /* default blink periods. */ <3 0x12 0 0x4105>, /* Reg 3,18 <- 0x4105 */ /* led[4]:rx, led[5]:dplx, led[45]:drive low off hiZ */ <3 0x13 0 0x0a60>; /* Reg 3,19 <- 0x0a60 */ }; phy6: ethernet-phy@6 { reg = <6>; compatible = "marvell,88e1118"; marvell,reg-init = /* Fix rx and tx clock transition timing */ <2 0x15 0xffcf 0>, /* Reg 2,21 Clear bits 4, 5 */ /* Adjust LED drive. */ <3 0x11 0 0x442a>, /* Reg 3,17 <- 0442a */ /* irq, blink-activity, blink-link */ <3 0x10 0 0x0242>; /* Reg 3,16 <- 0x0242 */ }; The Marvell PHYs have a page select register at register 22 (0x16), we can specify any register by its page and register number. These are the first and second word. The third word contains a mask to be ANDed with the existing register value, and the fourth word is ORed with the result to yield the new register value. The new marvell_of_reg_init function leaves the page select register unchanged, so a call to it can be dropped into the .config_init functions without unduly affecting the state of the PHY. If CONFIG_OF_MDIO is not set, there is no of_node, or no "marvell,reg-init" property, the PHY initialization is unchanged.

Driver appears to be mistaking the permission field with default value in the case of debug and qlge_irq_type. Driver is also passing debug as a bitmask into netif_msg_init() which wants a number of bits. Ron Mercer suggests we should change this to pass in -1 so the defaults get used instead, which makes the default much less verbose.

2010-11-22ALSA: azt3328: period bug fix (for PA), add missing ACK on stop timerAndreas Mohr1-8/+18
. Fix PulseAudio "ALSA driver bug" issue (if we have two alternated areas within a 64k DMA buffer, then max period size should obviously be 32k only). Back references: http://pulseaudio.org/wiki/AlsaIssues http://fedoraproject.org/wiki/Features/GlitchFreeAudio . In stop timer function, need to supply ACK in the timer control byte. . Minor log output correction When I did my first PA testing recently, the period size bug resulted in quite precisely observeable half-period-based playback distortion. PA-based operation is quite a bit more underrun-prone (despite its zero-copy optimizations etc.) than raw ALSA with this rather spartan sound hardware implementation on my puny Athlon. Note that even with this patch, azt3328 still doesn't work for both cases yet, PA tsched=0 and tsched (on tsched=0 it will playback tiny fragments of periods, leading to tiny stuttering sounds with some pauses in between, whereas with timer-scheduled operation playback works fine - minus some quite increased underrun trouble on PA vs. ALSA, that is).

Commit 8b592783 added a Thumb-2 variant of usracc which, when it is called with \rept=2, calls usraccoff once with an offset of 0 and secondly with a hard-coded offset of 4 in order to avoid incrementing the pointer again. If \inc != 4 then we will store the data to the wrong offset from \ptr. Luckily, the only caller that passes \rept=2 to this function is __clear_user so we haven't been actively corrupting user data.

2010-11-21e1000: fix screaming IRQAnupam Chanda1-4/+8
VMWare reports that the e1000 driver has a bug when bringing down the interface, such that interrupts are not disabled in the hardware but the driver stops reporting that it consumed the interrupt. The fix is to set the driver's "down" flag later in the routine, after all the timers and such have exited, preventing the interrupt handler from being called and exiting early without handling the interrupt.

2010-11-21ARM: improve compiler's ability to optimize page tablesRussell King1-0/+3
Allow the compiler to better optimize the page table walking code by avoiding over-complex pmd_addr_end() calculations. These calculations prevent the compiler spotting that we'll never iterate over the PMD table, causing it to create double nested loops where a single loop will do.

2010-11-19xen: re-enable boot-time ballooningJeremy Fitzhardinge1-2/+1
Now that the balloon driver doesn't stumble over non-RAM pages, we can enable the extra space for ballooning. Signed-off-by: Jeremy Fitzhardinge <[email protected]>
2010-11-19xen/balloon: make sure we only include remaining extra ramJeremy Fitzhardinge1-2/+5
If the user specifies mem= on the kernel command line, some or all of the extra memory E820 region may be clipped away, so make sure we don't try to add more extra memory than exists in E820. Signed-off-by: Jeremy Fitzhardinge <[email protected]>

The balloon_lock is useless, since it protects nothing against nothing. Signed-off-by: Jeremy Fitzhardinge <[email protected]>
2010-11-19xen: add extra pages to balloonJeremy Fitzhardinge2-4/+18
Add extra pages in the pseudo-physical address space to the balloon so we can extend into them later. Signed-off-by: Jeremy Fitzhardinge <[email protected]>

2010-11-19ext4: Add EXT4_IOC_TRIM ioctl to handle batched discardLukas Czerner1-0/+24
Filesystem independent ioctl was rejected as not common enough to be in core vfs ioctl. Since we still need to access to this functionality this commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch ext4_trim_fs(). It takes fstrim_range structure as an argument. fstrim_range is definec in the include/linux/fs.h and its definition is as follows. struct fstrim_range { __u64 start; __u64 len; __u64 minlen; } start - first Byte to trim len - number of Bytes to trim from start minlen - minimum extent length to trim, free extents shorter than this number of Bytes will be ignored. This will be rounded up to fs block size. After the FITRIM is done, the number of actually discarded Bytes is stored in fstrim_range.len to give the user better insight on how much storage space has been really released for wear-leveling.

2010-11-19fs: Do not dispatch FITRIM through separate super_operationLukas Czerner3-41/+0
There was concern that FITRIM ioctl is not common enough to be included in core vfs ioctl, as Christoph Hellwig pointed out there's no real point in dispatching this out to a separate vector instead of just through ->ioctl. So this commit removes ioctl_fstrim() from vfs ioctl and trim_fs from super_operation structure. Signed-off-by: Lukas Czerner <[email protected]> Signed-off-by: "Theodore Ts'o" <[email protected]>
