2006-11-30[ARM] Remove compatibility layer for ARM irqsRussell King

2006-11-30[ARM] Remove DEBUG_WAITQRussell King
DEBUG_WAITQ appears to have been removed by others, but no one removed the configuration option from ARM. Remote it from both Kconfig.debug and all default configurations. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Convert apm.c to use mutexes instead of semaphoresRussell King
More semaphore-as-mutex to mutex conversions. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Include asm/elf.h instead of asm/procinfo.hRussell King
These files want to provide/access ELF hwcap information, so should be including asm/elf.h rather than asm/procinfo.h Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Fix "apm -s" command hangRussell King
Fix an apparant hang with the "apm -s" command. We omitted to wake up this process once resume had completed. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-30[ARM] Improve reliability of APM-emulation suspendRussell King
The APM emulation can sometimes cause suspend to fail to work due to apparantly waiting for some process to acknowledge an event when it actually has already done so. We re-jig the event handling to work around this behaviour. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-26[ARM] Export smp_call_function()Russell King
smp_call_function() will be used with the MP/core oprofile support patch. Export it as _GPL. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-26[ARM] Add PM_LEGACY defaultsRussell King
Eliminate two warnings: kernel/power/pm.c:205: warning: 'pm_register' is deprecated (declared at kernel/power/pm.c:64) kernel/power/pm.c:206: warning: 'pm_send_all' is deprecated (declared at kernel/power/pm.c:180) by updating defconfig files to contain a sensible PM_LEGACY default.

2006-11-20[ARM] ebsa110: fix warnings generated by asm/arch/io.hRussell King
Remove two warnings: drivers/serial/8250_early.c:136: warning: unused variable 'mapsize' include/linux/io.h:47: warning: passing argument 1 of '__readb' discards qualifiers from pointer target type Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-20[ARM] 3933/1: Source drivers/ata/KconfigMartin Michlmayr
ARM doesn't source drivers/Kconfig like most architectures do, so the newly added drivers/ata is currently not made available on ARM. SATA is used on some ARM machines, like the Thecus N2100, so we need to source drivers/ata/Kconfig.

2006-11-14[ARM] Remove OP_MAX_COUNTERRussell King
OP_MAX_COUNTER never referenced, and is a reminant of an earlier oprofile implementation. Remove it. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-11-11[ARM] Remove PM_LEGACY=y from selected ARM defconfigsRussell King
Most ARM defconfigs don't actually need to have PM_LEGACY enabled. Disable it for ATEB9200, Collie, IXP4xx, OMAP H2, S3C2410 and Versatile. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-11-07[ARM] 3927/1: Allow show_mem() to work with holes in memory map.Ray Lehtiniemi
show_mem() was not correctly handling holes in the memory map. It was treating the freed sections of the map as though they contained valid struct page entries. This could cause incorrect debugging output or even a kernel panic. This patch keeps the struct meminfo around after system initialization so that show_mem() can use it when scanning memory. show_mem() now walks over each bank of each online node, rather than assuming that each node contains a single contiguous bank.

2006-11-07[ARM] 3926/1: make timer led handle HZ != 100David Brownell
The timer LED is unusable at HZ=large, since it's got a hard-wired value of 100 ticks per cycle; when HZ=1024 (for example) it's essentially always-on. This patch just makes that be HZ ticks per cycle. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-11-03[ARM] 3918/1: ixp4xx irq-chip reworkKevin Hilman
This is a rework of the ixp4xx irq_chip implementation. The use of two irq_chip structures and potentially switching between them is a violation of the intended use of the IRQ framework. The current implementation does not work with current in-kernel spinlock debugging or lockdep due to lock recursion problems caused by calling set_irq_chip/handler from within the chip's set_irq_type(). This patch goes back to using one irq_chip structure and handling the differences between edge/level, normal/GPIO interrupts inside the ack/mask/unmask routines themselves.

2006-11-02[ARM] 3912/1: Make PXA270 advertise HWCAP_IWMMXT capabilityPaul Gortmaker
ARM patch 3756/1 added HWCAP_IWMMXT. This patch adds support for broadcasting that info via /proc/cpuinfo and sets it for the CPU features of the PXA270. I've booted 19rc3 on a pxa270 and confirmed that the /proc/cpuinfo shows "iwmmxt" in the Features.

2006-10-04[PATCH] atmel_serial: Pass fixed register mappings through platform_dataHaavard Skinnemoen
In order to initialize the serial console early, the atmel_serial driver had to do a hack where it compared the physical address of the port with an address known to be permanently mapped, and used it as a virtual address. This got around the limitation that ioremap() isn't always available when the console is being initalized. This patch removes that hack and replaces it with a new "regs" field in struct atmel_uart_data that the board-specific code can initialize to a fixed virtual mapping for platform devices where this is possible. It also initializes the DBGU's regs field with the address the driver used to check against. On AVR32, the "regs" field is initialized from the physical base address when this it can be accessed through a permanently 1:1 mapped segment, i.e. the P4 segment. If regs is NULL, the console initialization is delayed until the "real" driver is up and running and ioremap() can be used.
