Revert "[PATCH] LOG2: Alter get_order() so that it can make use of ilog2() on a constant" This reverts commit 39d61db0. The commit was buggy in multiple ways: - the conversion to ilog2() was incorrect to begin with - it tested the wrong #defines, so on all architectures but FRV you'd never see the bug except for constant arguments. - the new "get_order()" macro used its arguments multiple times, and didn't even parenthesize them properly - despite the comments, it was not true that you could use it for constant initializers, since not all architectures even use the generic page.h header file. All of the problems are individually fixable, but it all boils down to: better just revert it, and re-do it from scratch.

This patch works back to 2.6.17 (earlier kernels seem to need up/down operations on mutex/semaphore). psmouse - properly reset mouse on shutdown/suspend Some people report that they need psmouse module unloaded for suspend to ram/disk to work properly. Let's make port cleanup behave the same way as driver unload. This fixes "bad state" problem on various HP laptops, such as nx7400.

The SMT scheduler incorrectly skips kernel threads even if they are runnable (but they are preempted by a higher-prio user-space task which got SMT-delayed by an even higher-priority task running on a sibling CPU). Fix this for now by only doing the SMT-nice optimization if the to-be-delayed task is the only runnable task. (This should cover most of the real-life cases anyway.) This bug has been in the SMT scheduler since 2.6.17 or so, but has only been noticed now by the active check in the dynticks code.

This patch fixes a possible race that leads to double freeing an idr index. When the master begin to close, release_dev() is called and then pty_close() is called: if (tty->driver->close) tty->driver->close(tty, filp); This is done without helding any locks other than BKL. Inside pty_close(), being a master close, the devpts entry will be removed: #ifdef CONFIG_UNIX98_PTYS if (tty->driver == ptm_driver) devpts_pty_kill(tty->index); #endif But devpts_pty_kill() will call get_node() that may sleep while waiting for &devpts_root->d_inode->i_sem. When this happens and the slave is being opened, tty_open() just found the driver and index: driver = get_tty_driver(device, &index); if (!driver) { mutex_unlock(&tty_mutex); return -ENODEV; } This part of the code is already protected under tty_mute. The problem is that the slave close already got an index. Then init_dev() is called and blocks waiting for the same &devpts_root->d_inode->i_sem. When the master close resumes, it removes the devpts entry, and the relation between idr index and the tty is gone. The master then sleeps waiting for the tty_mutex on release_dev(). Slave open resumes and found no tty for that index. As result, a NULL tty is returned and init_dev() doesn't flow to fast_track: /* check whether we're reopening an existing tty */ if (driver->flags & TTY_DRIVER_DEVPTS_MEM) { tty = devpts_get_tty(idx); if (tty && driver->subtype == PTY_TYPE_MASTER) tty = tty->link; } else { tty = driver->ttys[idx]; } if (tty) goto fast_track; The result of this, is that a new tty will be created and init_dev() returns sucessfull. After returning, tty_mutex is dropped and master close may resume. Master close finds it's the only use and both sides are closing, then releases the tty and the index. At this point, the idr index is free, but slave still has it. Slave open then calls pty_open() and finds that tty->link->count is 0, because there's no master and returns error. Then tty_open() calls release_dev() which executes without any warning, as it was a case of last slave close when the master is already closed (master->count == 0, slave->count == 1). The tty is then released with the already released idr index. This normally would only issue a warning on idr_remove() but in case of a customer's critical application, it's never too simple: thread1: opens master, gets index X thread1: begin closing master thread2: begin opening slave with index X thread1: finishes closing master, index X released thread3: opens master, gets index X, just released thread2: fails opening slave, releases index X <---- thread4: opens master, gets index X, init_dev() then find an already in use and healthy tty and fails If no more indexes are released, ptmx_open() will keep failing, as the first free index available is X, and it will make init_dev() fail because you're trying to "reopen a master" which isn't valid. The patch notices when this race happens and make init_dev() fail imediately. The init_dev() function is called with tty_mutex held, so it's safe to continue with tty till the end of function because release_dev() won't make any further changes without grabbing the tty_mutex. Without the patch, on some machines it's possible get easily idr warnings like this one: idr_remove called for id=15 which is not allocated.

Livio Soares authored
To the issue: some point during 2.6.20 development, Paul Mackerras introduced the "lazy IRQ disabling" patch (very cool work, BTW). In that patch, the performance monitor unit exception was marked as "maskable", in the sense that if interrupts were soft-disabled, that exception could be ignored. This broke my PowerPC profiling code. The symptom that I see is that a varying number of interrupts (from 0 to $n$, typically closer to 0) get delivered, when, in reality, it should always be very close to $n$. The issue stems from the way masking is being done. Masking in this fashion seems to work well with the decrementer and external interrupts, because they are raised again until "really" handled. For the PMU, however, this does not apply (at least on my Xserver machine with a 970FX processor). If the PMU exception is not handled, it will _not_ be re-raised (at least on my machine). The documentation states that the PMXE bit in MMCR0 is set to 0 when the PMU exception is raised. However, software must re-set the bit to re-enable PMU exceptions. If the exception is ignored (as currently) not only is that interrupt lost, but because software does not re-set PMXE, the PMU registers are "frozen" forever. [This patch means that performance monitor exceptions are taken and handled even if irqs are off, as long as some other interrupt hasn't come along and caused interrupts to be hard-disabled. In this sense the PMU exception becomes like an NMI. The oprofile code for most powerpc processors does nothing that is unsafe in an NMI context, but the Cell oprofile code does a spin_lock_irqsave. However, that turns out to be OK because Cell doesn't actually use the performance monitor exception; performance monitor interrupts come in as a regular interrupt on Cell, so will be disabled when irqs are off. -- paulus.] From: Livio Soares <livio@eecg.toronto.edu> Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

mmc: Power quirk for ENE controllers Support for these devices was broken for 2.6.18-rc1 and later by commit 146ad66e, which added voltage level support. This restores the previous behaviour for these devices by ensuring that when the voltage is changed, only one write to set the voltage is performed. It may be that both writes are needed if the voltage is being changed between two non-zero values or that it's safe to ensure that only one write is done if the hardware only supports one voltage; I don't know whether either is the case nor can I test since I have only the one SD reader (1524:0550), and it supports just the one voltage.

A previous cleanup misused need_poll, which had a fairly broken interface. It implemented a growable array, changing the used elements count itself, but leaving it up to the caller to fill in the actual elements, including the entire array if the array had to be reallocated. This worked because the previous users were switching between two such structures, and the elements were copied from the inactive array to the active array after making sure the active array had enough room. maybe_sigio_broken was made to use need_poll, but it was operating on a single array, so when the buffer was reallocated, the previous contents were lost. This patch makes need_poll implement more sane semantics. It merely assures that the array is of the proper size and that the contents are preserved. It is up to the caller to adjust the used elements count and to ensure that the proper elements are resent. This manifested itself as a hang in 2.6.20 as the uninitialized buffer convinced UML that one of its own file descriptors didn't support SIGIO and needed to be watched by poll in a separate thread. The result was an interrupt flood as control traffic over this descriptor sparked interrupts, which resulted in more control traffic, ad nauseum.

Fix insecure default behaviour reported by Tigran Aivazian: if an ext2 or ext3 or ext4 filesystem is tuned to mount with "acl", but mounted by a kernel built without ACL support, then umask was ignored when creating inodes - though root or user has umask 022, touch creates files as 0666, and mkdir creates directories as 0777. This appears to have worked right until 2.6.11, when a fix to the default mode on symlinks (always 0777) assumed VFS applies umask: which it does, unless the mount is marked for ACLs; but ext[234] set MS_POSIXACL in s_flags according to s_mount_opt set according to def_mount_opts. We could revert to the 2.6.10 ext[234]_init_acl (adding an S_ISLNK test); but other filesystems only set MS_POSIXACL when ACLs are configured. We could fix this at another level; but it seems most robust to avoid setting the s_mount_opt flag in the first place (at the expense of more ifdefs). Likewise don't set the XATTR_USER flag when built without XATTR support.

sata_sil used to trigger HSM error if IRQ occurs during polling command. This didn't matter because polling wasn't used in sata_sil. However, as of 2.6.20, all IDENTIFYs are performed by polling and device detection sometimes fails due to spurious IRQ. This patch makes sata_sil ignore and clear spurious IRQ while executing commands by polling. This fixes bug#7996 and IMHO should also be included in -stable.

Until recently all cx2341x firmware images were exactly 256KB, but newer firmware is larger than that and also appears to have arbitrary size. We still must check against a multiple of 4 bytes (because the cx23416 itself uses a 32 bit word size).

There are two errors that can lead to recovery problems with raid10 when used in 'far' more (not the default). Due to a '>' instead of '>=' the wrong block is located which would result in garbage being written to some random location, quite possible outside the range of the device, causing the newly reconstructed device to fail. The device size calculation had some rounding errors (it didn't round when it should) and so recovery would go a few blocks too far which would again cause a write to a random block address and probably a device error. The code for working with device sizes was fairly confused and spread out, so this has been tided up a bit.

After updating several machines to 2.6.20, I can't boot anymore the single one of them that supports the NX bit and is configured as a 32-bit system. My understanding is that the VDSO changes in 2.6.20-rc7 were not fully cooked, in that with that config option enabled VDSO_SYM(x) now equals x, meaning that an address in the fixmap area is now being passed to apps via AT_SYSINFO. However, the page is mapped with PAGE_READONLY rather than PAGE_READONLY_EXEC. I'm not certain whether having app code go through the fixmap area is intended, but in case it is here is the simple patch that makes things work again.
