This patch cleans up some code in xstate offsets computation in xsave area: 1. It changes xstate_comp_offsets as an array. This avoids possible NULL pointer caused by possible kmalloc() failure during boot time. 2. It changes the global variable xstate_comp_sizes to a local variable because it is used only in setup_xstate_comp(). 3. It adds missing offsets for FP and SSE in xsave area.

In standard form, each state is saved in the xsave area in fixed offset. But in compacted form, offset of each saved state only can be calculated during run time because some xstates may not be enabled and saved. We define kernel API get_xsave_addr() returns address of a given state saved in a xsave area. It can be called in kernel to get address of each xstate in xsave area in either standard format or compacted format. It's useful when kernel wants to directly access each state in xsave area.

__save_fpu() can be called during early booting time when cpu caps are not enabled and alternative can not be used yet. Therefore, it calls xsave_state_booting() during booting time to save xstate to task's xsave area.

Since boot_cpu_data and cpu capabilities are not enabled yet during early booting time, alternative can not be used in some functions to access xsave area. Therefore, we define two new functions xrstor_state_booting() and xsave_state_booting() to access xsave area just during early booting time. xrstor_state_booting restores xstate from xsave area during early booting time. xsave_state_booting saves xstate to xsave area during early booting time. The two functions are similar to xrstor_state and xsave_state respectively. But the two functions don't use alternatives because alternatives are not enabled when they are called in such early booting time. xrstor_state_booting is called only by functions defined as __init. So it's defined as __init and will be removed from memory after booting time. There is no extra memory cost caused by this function during running time. But because xsave_state_booting can be called by run-time function __save_fpu(), it's not defined as __init and will stay in memory during running time although it will not be called anymore during running time. It is not ideal to have this function stay in memory during running time. But it's a pretty small function and the memory cost will be small. By doing in this way, we can avoid to change a lot of code to just remove this small function and save a bit memory for running time.

We use legacy xsave/xrstor to save and restore standard form of xsave area in user space context. No xsaveopt or xsaves is used here for two reasons. First, we don't want to use modified optimization which is implemented in xsaveopt and xsaves because xrstor/xrstors might track a wrong user space application. Secondly, we don't use compacted format of xsave area for backward compatibility because legacy user space applications only don't understand the compacted format of the xsave area. Using standard form of the xsave area may allocate more memory for user context than compacted form, but preserves compatibility with legacy applications. Furthermore, even with holes, the relevant cache lines don't get touched and thus the performance impact is limited.

The XSAVE area header is changed to support both compacted format and standard format of xsave area. The XSAVE header of an xsave area comprises the 64 bytes starting at offset 512 from the area base address: - Bytes 7:0 of the xsave header is a state-component bitmap called xstate_bv. It identifies the state components in the xsave area. - Bytes 15:8 of the xsave header is a state-component bitmap called xcomp_bv. It is used as follows: - xcomp_bv[63] indicates the format of the extended region of the xsave area. If it is clear, the standard format is used. If it is set, the compacted format is used. - xcomp_bv[62:0] indicate which features (starting at feature 2) have space allocated for them in the compacted format. - Bytes 63:16 of the xsave header are reserved.

alternative_input_2() replaces old instruction with new instructions with input based on two features. In alternative_input_2(oldinstr, newinstr1, feature1, newinstr2, feature2, input...), feature2 has higher priority to replace oldinstr than feature1. If CPU has feature2, newinstr2 replaces oldinstr and newinstr2 is executed during run time. If CPU doesn't have feature2, but it has feature1, newinstr1 replaces oldinstr and newinstr1 is executed during run time. If CPU doesn't have feature2 and feature1, oldinstr is executed during run time.

This patch adds a kernel parameter noxsaves to disable xsaves/xrstors feature. The kernel will fall back to use xsaveopt and xrstor to save and restor xstates. By using this parameter, xsave area occupies more memory because standard form of xsave area in xsaveopt/xrstor occupies more memory than compacted form of xsave area. This patch adds a description of the kernel parameter noxsaveopt in doc. The code to support the parameter noxsaveopt has been in the kernel before. This patch just adds the description of this parameter in the doc.

The mapping from OF device IDs to platform device IDs is wrong. TYPE_NCPXXWB473 is 0, TYPE_NCPXXWL333 is 1, so ntc_thermistor_id[TYPE_NCPXXWB473] is { "ncp15wb473", TYPE_NCPXXWB473 } while ntc_thermistor_id[TYPE_NCPXXWL333] is { "ncp18wb473", TYPE_NCPXXWB473 }. So the name is wrong for all but the "ntc,ncp15wb473" entry, and the type is wrong for the "ntc,ncp15wl333" entry. So map the entries by index, it is neither elegant nor robust but at least it is correct.

In commit 9e8269de, support was added for ntc_thermistor devices being declared in the device tree and implemented on top of IIO. With that change, a dependency was added to the ntc_thermistor driver: depends on (!OF && !IIO) || (OF && IIO) This construct has the drawback that the driver can no longer be selected when OF is set and IIO isn't, nor when IIO is set and OF is not. This is a regression for the original users of the driver. As the new code depends on IIO and is useless without OF, include it only if both are enabled, and set the dependencies accordingly. This is clearer, more simple and more correct.
