It was a nice optimization - on paper at least. In practice it results in
branches that may exceed the maximum legal range for a branch. We can
fight that problem with -ffunction-sections but -ffunction-sections again
is incompatible with -pg used by the function tracer.By rewriting the loop around all simple LL/SC blocks to C we reduce the
amount of inline assembler and at the same time allow GCC to often fill
the branch delay slots with something sensible or whatever else clever
optimization it may have up in its sleeve.With this optimization gone we also no longer need -ffunction-sections,
so drop it.This optimization was originally introduced in 2.6.21, commit
5999eca25c1fd4b9b9aca7833b04d10fe4bc877d (linux-mips.org) rsp.
f65e4fa8e0c6022ad58dc88d1b11b12589ed7f9f (kernel.org).Original fix for the issues which caused me to pull this optimization by

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
ext4: BUG_ON fix: check if page has buffers before calling page_buffers() -
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove
to fail because of an incorrect usage count.The probe for this driver does a for_each_pci_dev() which gets a reference for
a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop
puts a reference for a pci_dev when iTCO_wdt_init() fails, so the
iTCO_wdt_init() does not need to do any pci_dev_put()'s.The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function.

For MMC1 Controller, card detect interrupt source is

card present/absent status by reading MMC Control register present
on twl6030. This functionality was introduced in mfd tree on
track to kernel.orgSync pandaboard to the same and make mmc work.

Adding card detect callback function and card detect configuration
function for MMC1 Controller on OMAP4.Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030.Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
the suspend/resume initialization which was done in omap_hsmmc_gpio_init
previously is moved to the probe thus making it generic for both OMAP3 &
OMAP4.Cc: Tony Lindgren
