devres: support sizes greater than an unsigned long

2014-11-07T18:09:07Z

As in 4f452e8aa492c0b8028ca9b4bdb4d018ba28c6c7, use resource_size_t to accomodate sizes greater than the size of an unsigned long int on platforms that have more than 32 bit physical addresses. Signed-off-by: Cristian Stoica Signed-off-by: Greg Kroah-Hartman

Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2014-08-06T00:46:42Z

Pull timer and time updates from Thomas Gleixner: "A rather large update of timers, timekeeping & co - Core timekeeping code is year-2038 safe now for 32bit machines. Now we just need to fix all in kernel users and the gazillion of user space interfaces which rely on timespec/timeval :) - Better cache layout for the timekeeping internal data structures. - Proper nanosecond based interfaces for in kernel users. - Tree wide cleanup of code which wants nanoseconds but does hoops and loops to convert back and forth from timespecs. Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"? I don't think that word means what you think it means ] - Another round of code move from arch to drivers. Looks like most of the legacy mess in ARM regarding timers is sorted out except for a few obnoxious strongholds. - The usual updates and fixlets all over the place" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (114 commits) timekeeping: Fixup typo in update_vsyscall_old definition clocksource: document some basic timekeeping concepts timekeeping: Use cached ntp_tick_length when accumulating error timekeeping: Rework frequency adjustments to work better w/ nohz timekeeping: Minor fixup for timespec64->timespec assignment ftrace: Provide trace clocks monotonic timekeeping: Provide fast and NMI safe access to CLOCK_MONOTONIC seqcount: Add raw_write_seqcount_latch() seqcount: Provide raw_read_seqcount() timekeeping: Use tk_read_base as argument for timekeeping_get_ns() timekeeping: Create struct tk_read_base and use it in struct timekeeper timekeeping: Restructure the timekeeper some more clocksource: Get rid of cycle_last clocksource: Move cycle_last validation to core code clocksource: Make delta calculation a function wireless: ath9k: Get rid of timespec conversions drm: vmwgfx: Use nsec based interfaces drm: i915: Use nsec based interfaces timekeeping: Provide ktime_get_raw() hangcheck-timer: Use ktime_get_ns() ...

of: Provide a function to request and map memory

2014-07-23T10:02:30Z

A call to of_iomap does not request the memory region. This patch adds the function of_io_request_and_map which requests the memory region before mapping it. Signed-off-by: Matthias Brugger Suggested-by: Thomas Gleixner Suggested-by: Rob Herring Acked-by: Rob Herring Signed-off-by: Daniel Lezcano

devres: remove devm_request_and_ioremap()

2014-06-20T03:01:36Z

devm_request_and_ioremap() was obsoleted by the commit 7509657 ("lib: devres: Introduce devm_ioremap_resource()") and has been deprecated for a long time. So, let's remove this function. In addition, all usages of devm_request_and_ioremap() are also removed. Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman

lib/devres.c: use dev in devm_request_and_ioremap

Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP

2014-04-07T23:36:11Z

If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König Acked-by: Arnd Bergmann Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lib/devres.c: fix some sparse warnings

2014-04-03T23:21:11Z

Having a discussion about sparse warnings in the kernel, and that we should clean them up, I decided to pick a random file to do so. This happened to be devres.c which gives the following warnings: CHECK lib/devres.c lib/devres.c:83:9: warning: cast removes address space of expression lib/devres.c:117:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:117:31: expected void [noderef] * lib/devres.c:117:31: got void * lib/devres.c:125:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:125:31: expected void [noderef] * lib/devres.c:125:31: got void * lib/devres.c:136:26: warning: incorrect type in assignment (different address spaces) lib/devres.c:136:26: expected void [noderef] *[assigned] dest_ptr lib/devres.c:136:26: got void * lib/devres.c:226:9: warning: cast removes address space of expression Mostly it's just the use of typecasting to void * without adding __force, or returning ERR_PTR(-ESOMEERR) without typecasting to a __iomem type. I added a helper macro IOMEM_ERR_PTR() that does the typecast to make the code a little nicer than adding ugly typecasts to the code.

lib/devres.c: fix misplaced #endif

2013-02-28T03:10:09Z

A misplaced #endif causes link errors related to pcim_*() functions. This is because pcim_*() functions are related to CONFIG_PCI option, however these are not related to CONFIG_HAS_IOPORT option. Therefore, when CONFIG_PCI is enabled and CONFIG_HAS_IOPORT is not enabled, it makes link errors related to pcim_*() functions as below: drivers/ata/libata-sff.c:3233: undefined reference to `pcim_iomap_regions' drivers/ata/libata-sff.c:3238: undefined reference to `pcim_iomap_table' drivers/built-in.o: In function `ata_pci_sff_init_host': drivers/ata/libata-sff.c:2318: undefined reference to `pcim_iomap_regions' drivers/ata/libata-sff.c:2329: undefined reference to `pcim_iomap_table Signed-off-by: Jingoo Han Cc: Greg KH Cc: Tejun Heo Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

lib: devres: Fix build breakage

2013-01-22T21:31:18Z

The ERR_PTR() and IS_ERR() macros used by the devm_ioremap_resource() function are defined in the linux/err.h header. On ARM this seems to be pulled in by one of the other headers but the build fails at least on OpenRISC. Signed-off-by: Thierry Reding Reported-by: kbuild test robot Signed-off-by: Greg Kroah-Hartman
