[ARM PATCH] 2430/3: TLS support for ARM

ChangeSet 1.1983.1.17, 2005/02/01 15:00:58+00:00, nico <at> org.rmk.(none)

	[ARM PATCH] 2430/3: TLS support for ARM
	
	Patch from Nicolas Pitre
	
	This implements TLS support in the most efficient way for all ARM
	processors in use today.  The trick is to define a specific address in
	kernel area that is made readable from user space to hold the TLS
	pointer so it is highly efficient to retrieve it with no overhead.
	Since the kernel already maps a page at 0xffff0000 to hold the exception
	vectors, we can use the top of that page for storing the TLS ptr at
	0xffff0ffc. This address has the advantage of fitting optimally with the
	ARM load addressing mode as follows:
		mov	rd, #0xffff0fff
		ldr	rd, [rd, #-3]
	Considering load scheduling, this means 2 cycles to retrieve the TLS
	value which is even faster than a coprocessor access.  Even gcc
	generates the above assembly when given:
		void *tls = *((void **)0xffff0ffc);
	This is fine to make the vector page readable from user space since it
	contains nothing that could compromize security and doesn't require an
	extra memory page to be allocated.
	On SMP (which should be ARMv6 and above only) the special reg for
	TLS will be available.  Since ARMv6 binaries are most likely to use
	strex/ldrex insns instead of swp to implement user space atomic
	primitives, those ARMv6 binaries won't execute on pre ARMv6 processors
	anyway.  So the abscence of a tls reg is a non issue for them already.
	Also on SMP targets, since the hivec page can't be relied upon to get
	the TLS value, we'll have the kernel emulate access to it through the

[ARM PATCH] 2443/1: enable iWMMXt on EABI binaries

ChangeSet 1.1983.1.18, 2005/02/01 15:43:40+00:00, nico <at> org.rmk.(none)

	[ARM PATCH] 2443/1: enable iWMMXt on EABI binaries
	
	Patch from Nicolas Pitre
	
	It appears that the EF_ARM_SOFT_FLOAT is a reserved bit with the new
	ARM EABI.  Since EABI is said to not support FPA (FPA emulation being
	the reason why we'd want to disable iWMMXt access) we now test for any
	EABI version as well to turn on iWMMXt access.

[ARM] Remove adrsvc macro.

ChangeSet 1.1983.1.16, 2005/02/01 12:57:22+00:00, rmk <at> flint.arm.linux.org.uk

	[ARM] Remove adrsvc macro.
	
	The adrsvc macro was used to allow the entry-* files to be built on
	ARM32 and ARM26 processors.  Since we no longer support ARM26 CPUs,
	eliminate this macro.

SCSI: fix multiple HBA problem with transport classes

	SCSI: fix multiple HBA problem with transport classes
	
	All of the transport class patches contain a thinko in device matching
	(and, unfortunately, one I exhorted everyone not to make in the generic
	transport class comments): The match matches every container in the
	class instead of the specific container belonging to the HBA.  This
	causes a oops when there are two or more HBAs in the system.
