ARM: 8322/1: keep .text and .fixup regions closer together

2015-03-29T22:11:56+00:00

This moves all fixup snippets to the .text.fixup section, which is
a special section that gets emitted along with the .text section
for each input object file, i.e., the snippets are kept much closer
to the code they refer to, which helps prevent linker failure on
large kernels.

ARM: Fix csum_partial_copy_from_user()

2010-07-26T11:18:16+00:00

Using the parent functions frame pointer to access our arguments is
completely wrong, whether or not we're building with frame pointers
or not.  What we should be using is the stack pointer to get at the
word above the registers we stacked ourselves.

ARM: fix build error in arch/arm/kernel/process.c

2010-04-21T07:45:21+00:00

/tmp/ccJ3ssZW.s: Assembler messages:
/tmp/ccJ3ssZW.s:1952: Error: can't resolve `.text' {.text section} - `.LFB1077'

This is caused because:

	.section .data
	.section .text
	.section .text
	.previous

does not return us to the .text section, but the .data section; this
makes use of .previous dangerous if the ordering of previous sections
is not known.

Fix up the other users of .previous; .pushsection and .popsection are
a safer pairing to use than .section and .previous.

[ARM] 5231/1: Do not save the frame pointer in the csum_partial_copy_* functions

2008-09-01T11:06:35+00:00

Since the other assembly functions do not seem to save the frame
pointer onto the stack, this patch changes the csum_partial_copy_*
functions to behave in the same way.

[ARM] 5227/1: Add the ENDPROC declarations to the .S files

2008-09-01T11:06:34+00:00

This declaration specifies the "function" type and size for various
assembly functions, mainly needed for generating the correct branch
instructions in Thumb-2.

[ARM] 3256/1: Make the function-returning ldm's use sp as the base register

2006-01-12T16:53:51+00:00

Patch from Catalin Marinas

If the low interrupt latency mode is enabled for the CPU (from ARMv6
onwards), the ldm/stm instructions are no longer atomic. An ldm instruction
restoring the sp and pc registers can be interrupted immediately after sp
was updated but before the pc. If this happens, the CPU restores the base
register to the value before the ldm instruction but if the base register
is not sp, the interrupt routine will corrupt the stack and the restarted
ldm instruction will load garbage.

Note that future ARM cores might always run in the low interrupt latency
mode.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

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!
