2008-06-21Add a bunch of cycle_kernel_lock() callsJonathan Corbet2-2/+4
All of the open() functions which don't need the BKL on their face may still depend on its acquisition to serialize opens against driver initialization. So make those functions acquire then release the BKL to be on the safe side. Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2008-06-21Add "no BKL needed" comments to several driversJonathan Corbet1-1/+1
This documents the fact that somebody looked at the relevant open() functions and concluded that, due to their trivial nature, no locking was needed. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2008-02-08CRIS v10: Cleanup of drivers/gpio.cJesper Nilsson1-32/+29
- Change parameters of gpio_write (const char * buf -> const char __user *buf) - Don't initialize static variables to zero. - Remove useless casts from void. - Change name of interrupt routine (gpio_pa_interrupt -> gpio_interrupt) - Use kzmalloc instead of allocating memory and zeroing it manually. - Correct casts for copy_to_user and copy_from_user to (void __user *) - Make file_operations gpio_fops static. - Make ioif_watcher static, not used outside this file.

2008-02-08CRIS v10: Update drivers/gpio.c, fix locking and general improvements.Jesper Nilsson1-359/+228
- Change all spin_lock/local_irq_save to spin_lock_irqsave. - Change multiple returns in functions where we have a lock to goto out. - Correct number of arguments to gpio_poll_timer_interrupt, gpio_pa_interrupt. - Break out gpio_write logic to smaller functions to make it readable. - In setget_input and setget_output, avoid extra if-indent level. - Change name LED_* -> CRIS_LED_* to avoid name clash. - Don't use braces around single statement ifs. - Fix whitespace errors. - Remove useless CVS id and log.

2008-02-08CRIS v10: Update driver for pcf8563Jesper Nilsson1-173/+220
- Use mutex instead of spinlock, fixes kernel bugzilla report 8339. - Make sure that pcf8563_init can be called multiple times but only setup once. - Change RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR - Cache the voltage low value at driver init so the battery status information does not get 'accidentally' cleared when setting the RTC time. - Add weekday handling. - Correct leapyear handling to include 100 and 400 year exceptions. - Correct whitespace and formatting errors. - Remove useless CVS id tag.
2008-02-08CRIS v10: Fix bugs in i2c_init and i2c_readregJesper Nilsson1-78/+3
- Set the variable first to zero after first setup, so we can stop multiple calls to i2c_init from trying to setup i2c. - The last byte read by the master in an i2c transfer needs to be NACKed, not ACKed. - Also, remove useless CVS log and CVS id tags.

2008-02-05CRIS: avoid using arch links in KconfigJesper Nilsson1-0/+4
Improve including of architecture dependent Kconfig files. - Always include the architecture dependent Kconfig files. - Wrap architecture dependent Kconfig files inside an appropriate "if ETRAX_ARCH_Vxx" block.

2007-11-15cris build fixes: corrected and improved NMI and IRQ handlingJesper Nilsson1-0/+1
Corrects compile errors and the following: - Remove oldset parameter from do_signal and do_notify_resume. - Modified to fit new consolidated IRQ handling code. - Reverse check order between external nmi and watchdog nmi to avoid false watchdog oops in case of a glitch on the nmi pin. - Return from an pin-generated NMI the same way as for other interrupts. - Moved blocking of ethernet rx/tx irq from ethernet interrupt handler to low-level asm interrupt handlers. Fixed in the multiple interrupt handler also. - Add space for thread local storage in thread_info struct. - Add NO_DMA to Kconfig, and include arch specific Kconfig using arch independent path.

2007-02-12[PATCH] mark struct file_operations const 2Arjan van de Ven5-5/+5
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering1-1/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-31[PATCH] fix missing includesTim Schmielau1-0/+1
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds9-0/+5068
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
